Impact crusher (impcat crusher) and hammer crusher (hammer crusher), all impact the role of broken, except the following

points.

Hammer fixed crusher mounted on the rotor, when broken, can take full advantage of the energy of the entire rotor, crushing

the bulk material.
The bottom of the crusher does not grate bars, and product size determined by the counter-attack the gap between the plate

and hammer, so to avoid crushing the wet material from clogging the grate.
Crusher back plate and large crushing chamber, the crushing of the material not only by the impact of the hammer, more

important is the use of repeated impact between the self-feed with the back plate or materials and materials.
The Yuanhua crusher work, the rotor rotate at high speed material feed port through the sieve with fine-grained separation,

large chain behind the shock by the hammer was broken for the first time, production at great speed thrown to the back plate

was again broken, and then from the back plate bounced back the hammer strike zone, continue to repeat the above process, the

commuting of the material in between the hammer and the back plate, collide. Materials after repeated shocks, broken into

small pieces along the joint surface. When the particle size is less than the gap between the hammer and the back plate, you

can enter a crushing chamber, and then repeatedly broken until you have reached the required particle size begins inside the

lower part of the discharge.

Compared with traditional lighting, LED lighting has many unique, mainly: From a structural point of view, the traditional lighting of the light source and lighting are separated, while the LED lighting in the structure can be achieved with light, heat and lighting one design; from a functional point of view, only a small part of the traditional lighting dimming, LED lighting can not only adjust the brightness, but also color and color temperature adjustment. In addition, LED lighting is more suitable than the traditional lighting of intelligent digital control, composed of a complex lighting system.

Based on these characteristics of the LED lighting, can be roughly given three models for universal LED lighting, LED lighting intelligent control, LED lighting and solar wind combined with design, description of electronic and information technology in LED lighting in some applications.

Model: Power + Light

The essence of the modern electric light to electrical energy into light energy, accompanied by certain cooling. Of LED general lighting model includes only the power supply and light source in two parts. Under this model, only the lighting switch control, not the lighting, dimming, communication, feedback, and other functions.

Power specifically refers to the AC-DC constant current switching power supply. AC-DC refers to the conversion of AC to DC, because the LED is actually a semiconductor diode, it is the work of the DC voltage. LED there is a feature that is an approximation of the operating current is an exponential function of operating voltage, small voltage fluctuations can cause huge changes in the current, and in severe burning LEDs, so to ensure the safety of LED, you must be a constant operating current . Usually home appliances are constant voltage power supply and LED characteristics determines it to be a constant current power supply. In order to improve the reliability of the LED work, we generally isolated switching power supply to achieve the effective isolation of the LED and the electricity grid. Corresponding to the switching power supply, a class called linear power supply, is now rarely used, the more dominant of the switching power supply efficiency and volume. The switching power supply technology, can conversion efficiency to achieve the 85% or even higher power factor above 0.95, the total harmonic in less than 15%. These indicators we have chosen the basic requirements of the switching power supply.

The light source is LED chip, which is the core component of the LED lighting. In addition to the electrical parameters of the operating current, tube voltage drop, we are more concerned about its optical indicators, such as luminous flux, luminous efficiency, color temperature, color rendering index, the light fades and so on. LED optical performance is closely related to its temperature, the temperature will cause to reduce the luminous efficiency, color temperature drift, life expectancy decreased cooling technology in LED lighting is particularly important. Thermodynamic knowledge tells us that the heat of the object only three ways: conduction, convection and radiation. LED chip is fixed to issue a certain wavelength of visible light, so there is no cooling of infrared radiation. The LED heat conduction, accompanied by a certain amount of convective cooling. Reduce the heat conduction of the LED link and reduce the thermal resistance of each link, if necessary, forced air cooling are thermal design considerations.
 

Model 2: Power + Control + Light

Model two model more than one function of a control module, which greatly enriched the LED lighting. If the model is a lighting products, then the second model can be said is a lighting system. Joined the control module, power becomes a constant voltage type switching power supply, LED light source or constant current power supply is needed, this part of the (constant current drive) on the control module to achieve together. Below, we focus on LED lighting control system.

LED lighting control system, can be very flexible, feature-rich. Such as: wireless remote dimming system, color temperature, adjustable lighting system, the color system of RGB dimming, simulated daylight lighting systems, intelligent lighting system with DALI protocol, ZigBee and GPRS-based wireless street light control system and so on. Through the phenomenon of nature, all of these lighting control system are the use of electronic technology in the field of embedded technology, communication technology, sensor technology, computer technology and power electronics technology development established. Seemingly numerous and complicated, in fact, based on evidence.

In order to clarify the context, the LED lighting control system is divided into eight levels, layer by layer described. If we can each level technical solutions to do any complex control system, we can be like \"building blocks\" like easy implementation.

8 level LED lighting control system from the bottom up as follows: supply layer and driver layer, the optical layer, the sensor layer, the proposed layer, letter layer for layer, system implementation layer.

Supply layer

Highly efficient and stable DC power supply layer for the entire control system. Work with the LED light source constant current power supply control system work is a constant voltage power supply. Power supply layer there are two ways: First, to obtain from the constant voltage power supply, LED lighting, which is a DC-DC (DC to DC) conversion, because the lamps on the constant voltage power supply voltage is usually high , while the low voltage control system, do so from a DC to DC buck converter; is obtained from the AC power, which is an AC-DC (AC to DC) converter, for safety, usually do into isolated switching power supply, control system power consumption is usually low, so the constant voltage power supply requirements for conversion efficiency is not very high.

State LED energy-saving lamps is too expensive can not solve the problem. Involving thousands of families of indoor lighting, indoor lighting market is bigger than the outdoor lighting market after the real popularity of LED lighting, LED used in the rendering of the interior lighting is the atmosphere, with any other light sources have an unparalleled advantage, but in The domestic market is concerned, the price is still too high, the majority of the people can not afford that. According to the analysis of the the ECCO Chinese official website, causing the LED to your main for the following reasons:

1, the domestic enterprises, the core technology

Upstream of the LED industry, most of the core patent lies in the hands of foreigners, we do not grasp the core technology, although the manufacturing capacity of LED application products accounted for 50% of the global share to 50 percent, but profit is indeed one of the lowest . LED chip with the process, increase in the number of larger wafer production process, will continue to reduce costs, reduce the rate of 20% annually in recent years, the LED chip price factor, to luminous efficiency enhancement also included in the price reduction the same price to buy a better product. The cost of LED lighting in the LED chip, chip price down of LED lumens Price dropped of at this stage of energy-saving lamps, interior lighting, natural everywhere. LED chip is still a great room for price cuts.

2, LED application product cooling difficult
Would account for about 20 percent in the structural design of the lighting in industrious people will have been priced very low, 20% of the cost very reasonable, the biggest problem is how to be more innovative, the design is more reasonable.
Cooling costs to be maintained at 5%, the actual thermal design is very simple and protect the two directions: First, the LED chip and the external heat sink paths as short as possible, the shorter the better your thermal design; heat resistance is sufficient heat reached the path must also have the cooling-road "in this part of the cost structure is not much used in cooling costs.

3, the weak power of LED application
The power LED lighting is the weakest link, is seriously lagging behind the development of LED lighting, the quality needs to be improved. Design accounted for about 20% of the cost of lamps, some as high. As the technology development of power in about 5-10% of the most reasonable.
LED costs are high compared with other light, as in the 1990s before the invention of blue LED, the LED industry, leading to the white LED can be achieved, in fact, now the cost is not high. LED environmental protection, energy saving, no mercury, and every quarter of the price of LED lamps are sliding down, I believe we can achieve the acceptable level within a short period of time.

Road construction, there are many factors affecting the strength of concrete, including the strength of the cement, water-cement ratio, aggregate, Senate combined materials such as aggregates, especially direct the surface of the aggregate impact of the cement paste and aggregate stick knot, thus affecting the strength of concrete; rough gravel surface, the bond strength; flakiness of aggregate, strength, adhesive force is small, the aggregate of the cube greatly improve the device performance of concrete; aggregate The particle size also affect the strength of the concrete, aggregate the smaller the particle size the greater the strength of the concrete. Therefore, how to select the appropriate set of sand making machinery, determine the success or failure of the aggregate production and investment business.

Followed in order to focus on the LED lighting all kinds of skills and functional growth of the "hard" has gradually satisfied the request of the traditional light sources in a number of lighting areas, and its focus on energy saving and environmental protection for the "soft

"Using more and more discouraged and, traditional lighting industries and enterprises in diverse participation in led lighting market, beginning to explore the transformation of the Road, which led the outbreak of the first year, whether the traditional lighting of the withered

Off the start? Of the world s largest exhibition for the 2011 Guangzhou International Lighting Fair as the industry s top event, often can perhaps pass the information on the performance of the industry limelight – the first time became the world s largest lighting exhibition

, The Dibon only a single LED to open an exhibition exhibition also became the world s largest LED Fair.

       According to the study of wood experts, the reason why natural wood products has long been welcomed by human, the most important factor is the affinity of wood,

including wood and comfortable, constant temperature, workability, and appearance of natural beauty, especially suitable for human practical and aesthetic

requirements. Natural materials, wood is the closest to the process of human development and human, but the misfortune of the forest resources and thus was born the

last century, our country on the trees disorderly logging and abuse, resulting in excessive destruction of natural forests. According to the global forest map drawn by

Greenpeace, currently China s intact forests account for only 2% of the total forest area in the conditions of China s per capita forest resources is equivalent to

only 1/5 of the world s per capita consumption of the Government to formulate strict control measures to ensure that the growth and recovery of forest resources,

resulting in major forestry enterprises has never been the main industry, deforestation difficult. China is a traditional timber-consuming countries, the current

annual domestic demand for wood is about 300 million cubic meters, over the years, the consumption data analysis, domestic maximize only likely to provide about 200

million cubic meters of timber, wood supply gap about 100 million cubic meters.
       From the WPC material or products associated with some of the performance is similar to natural wood, wood and resin materials, the three major advantages of

natural wood – material comfort, natural texture, smell fragrant, wood materials can imitate. According to reports, the country had seen of the WPC material as a

natural timber to be detained, WPC material as real natural wpc wood is evident. Another example is the shortest of natural wood, a board — corrosion resistance, wood

fear of water, afraid of the tide, easy to mold, insects and other issues because the corrosion resistance into the sky, one of the biggest characteristics of the WPC

material is water resistance moisture. WPC enterprises for sales promotion needs, simply do a huge fishbowl, wood products on the fish tank on display. Another piece

of wood short board is toughness, strong and insufficient rigidity, its biggest problem is poor dimensional stability. WPC materials by multi-component formulation of

raw materials composite can have the flooding does not rise, drying without cracking, termites do not decay away from the fire Jimie, durability and other advantages

of the process requirements can also be in accordance with the market and the needs of users make improvements. The plasticity of synthetic materials WPC materials

with greater room for adjustment, and they can make up some of the elemental material defects, for example, that may change some of the natural wood products. U.S.

forest products industry began to put the wood materials as no maintenance will be able to increase the wood durability of new materials, and is its biggest selling

point to enter the market. Of course, in addition to the characteristics of the material itself, a more grim reality is that the implementation of the National

Environmental Policy and an increasingly tight timber limits to logging, wood products had to turn to find a new alternative material source. WPC materials and the

wood has a natural kinship can not be said to be the most competitive candidates.

       The scope of application of the WPC almost covers the use of wood, plastic, ceramic, steel, aluminum and other similar composite field has begun to penetrate

the building, home improvement, furniture, automotive, transportation, logistics, packaging, garden, municipal, environmental protection, sports, even in the military

field, radiating, and influence is gradually expanding, very broad application prospects. With the establishment of the concept of circular economy, and, increasingly,

is not optimistic the scarcity of resources, the WPC enterprises have realized the tremendous business opportunities that may result. Objective point of view, our

natural wood resources are dwindling and the market in the growing demand for wood products. Applications from the market demand analysis, domestic WPC enterprises are

most likely to begin large-scale development in the following areas:
       1, the construction industry: including the substrate, wall materials, templates, flooring and decorative materials series;
       2, the furniture industry: such as wardrobes, cabinets, tables, chairs, coffee table, Shelf series;
       Garden industry: including fencing, floor decking, columns, handrails and other landscape series;
       4, the logistics industry: the main box, container board, all kinds of pallet series;
       5, the transport sector: for example, fences, partitions, parapets, signs, sleepers series.
       Such as the recent WPC successfully wood plate as a substrate of wood laminate flooring, the flooring industry, which moved to look into a vast source of raw

materials, so very happy to close the WPC industry. WPC industry in terms of ambitious expansion, development, and into the wood flooring industry has a relatively

mature market system would be a wise choice. The wpc floor is also in the material on a new experiment to expand the living space for themselves. This point, the same

with the wood floor with the raw pain of the furniture industry is also working with the WPC industry is in frequent contact in order to find new sources of raw

materials. Regarding the use of the compound advantages of WPC materials, some of the more complex combinations of materials experiments is the development trend of

the field of new materials in recent years. For example, Japan is the use of composite materials used in the new generation of high-speed train, its purpose is to

reduce noise, reduce vibration and low power consumption to maintain the temperature inside.

Innovation and the world\\ s most prominent companies, often together, such as Mercedes-Benz, Apple, IBM, Sony, Haier and so on. Even the water heater market in China, the international brand innovation to monopolize the Chinese market.

Japan despotic rate, dominated the market of gas water heater become the leader of Western power to send the AO Smith Corporation and Siemens to divide up almost half of the storage-type electric water heater market share … Most Chinese water heater business by taking the low price route, the lack of capital investment in technological innovation and R & D , leading to a severe shortage of competitiveness. China\\ s water heater business as a whole is under threat.

 
If you can not change the status quo, the water heater industry is likely to step automotive industry has followed almost completely monopolized by foreign enterprises. Chinese home appliance industry is the most desired new structure competitive.

Innovation, we must ask for a brand, an enterprise has a strong brand concept and industrial mission, there is a benefit of the universal spirit of humanity, one can lead the industry as a whole progress of courage, one has a comprehensive innovation and breakthrough capabilities.

A successful and innovative enterprises, often business excellence in this industry, this industry \"symbol brand. A more state-owned industries \"symbol brand\", that is, the well-being of this country.

In 2005, a cutting-edge, innovative high-tech enterprises to develop the first fast electric water heater has independent intellectual property rights in China, the one listed immediately sought after by the global. Speed ??thermal electric water heater is a real Chinese creative product, speed electric hot water heater category output value is not large, but the speed thermal electric water heater contains national value of wealth is far greater than the wealth of industrial manufacturing.

wood plastic composite materials research and development work began in the 1990s, 10 years later than the foreign wood-plastic composite materials research and development. Since the late 1990s, with Europe and the United States and other countries to limit the wood packaging from China, R & D and technology transfer of the domestic woodplastic material into a period of rapid development. To the beginning of this century, had become the domestic wood-plastic industry prototype.
          WPC industry as a multi-directional span of the specialization edge emerging industry, its equipment, technology and processes related to the precision machinery, fine chemical, hydraulic transmission, vacuum technology, heat conduction, fluid dynamics, sensor technology, electronic Controls and computer programming, and many other disciplines and professional, the Chinese wood-plastic support and cooperation of many professional organizations, through the continuous development and innovation, has been gradually self-contained. National circular economy policy to encourage and promote the potential benefits of the demand for dual-powered, the national wood-plastic heat is gradually emerging. According to incomplete statistics, as of the end of 2006, directly or indirectly engaged in wood-plastic composite materials research and development, production and support for over 150 enterprises and institutions, this trend also in the ascendant, including state, private, sole proprietorship, partnership and joint ventures and other various types. Wood-plastic industry, employing tens of thousands of people, production capacity is greatly improved, wood products annual sales of over 120 thousand tons, annual output value of more than 2 billion yuan. From a global perspective, has become a following in North America, the development trend and market capacity is the most optimistic region.
          Domestic wood-plastic business geographical distribution, the eastern far more than in the west, where the highest concentration of wood-plastic enterprises in the Pearl River Delta and Yangtze River Delta region; to process the theory of the level of individual enterprises in eastern technology is more advanced; enterprises in the South will hold the number of products and markets an absolute advantage. A number of backbone enterprises in the industry to meet or exceed the international advanced level, the rest a lot of companies are gradually highlights the characteristics of their products. Chinese WPC industry is one of the domestic manufacturing one of the few to be able to dialogue with the developed countries in Europe and the United States equal industry, the Chinese wood-plastic ready to prepare the world.

Implementation plan, "according to the National Development and Reform Commission published" 12 crop straw comprehensive utilization of straw comprehensive utilization rate will reach 75 percent by 2013, to strive straw comprehensive utilization in 2015 of more than 80%. In addition to the common traditional areas of the straw fertilizer, feed, binder of raw materials and fuel and other wood-plastic new materials make an excellent contribution to the crop stalk.
wood plastic composite material is a natural fiber-based raw materials to produce new ecological materials, both the dual characteristics of wood and plastic products to the performance indicators comparable with hardwood products, excellent mechanical properties, light weight, waterproof, anti- pH, does not rot, anti-moth-eaten, and can 100% recycled use of green products in the true sense. In the consumption of straw, "tasteless" and resources to effectively protect environmental resources while also providing consumers with new options for creating a harmonious society saving is of strategic importance, it can be said to be a win-win choice between man and nature.
woodplastic products can replace wood, some plastics, aluminum and steel materials, products, generally used in many indoor and outdoor environment, the 2012 global economy will gradually recover, the pace of development in the construction industry will also begin a slow recovery, the global construction industry development prospects optimistic, WPC has great market potential.
