How it is working? 1 Center Feeding: Raw material falls down into feed hopper, and then enters impeller through central entrance hole. It is accelerated in high speed impeller, and then is thrown out at speed of 60-75 m/s. When hitting impact plate, it is crushed.
Final products eaten though outlet downwards. 2 Ring Feeding: Raw material falls down into feed hopper, and then through ring, it is divided into two parts by material-dividing plate. One enters into impeller speed through the center of material-dividing plate. The other falls down from outside of material-dividing plate. Material, which is thrown out by impeller at speed of 60-75 m/s hits material coming from outside of material-dividing plate down. In this way, material is crushed. Our company manufactures various kinds of sand maker and HX series impact crusher.

LED light bulbs have a slight environmental edge on compact fluorescent bulbs and both trump traditional incandescent bulbs by a wide margin, the Pacific Northwest National Laboratory says in a new report. PNNL, U.S. Department of Energy lab based in Richland, Wash., compared the environmental footprint of the three bulbs, including mining of raw materials, manufacturing, disposal and electricity use. It’s the first public report to examine the impact of LED manufacturing in depth, the lab says. Among the study s conclusions: * Both LEDs and CFLs are substantially more environmentally friendly than traditional incandescents, which consumes far more electricity the dominant environmental impact. Switching away from incandescents reduces the environmental harm of lighting by three to 10 times. * Today s par20 led light cause slightly less environmental harm than compact fluorescents in 14 of 15 areas studied.
Those areas include global warming potential, land use and pollution of water, soil and air. The LED bulb s main environmental drawback is its use of an aluminum heat sink at the bottom of the bulb. That s because mining and processing aluminum is energy intensive and generates sulfuric acid and other hazardous byproducts. * By 2017, LED bulbs will have half the impact of today s epistar led flood light and 70 percent less impact than today s CFLs, which are not expected to change significantly. LED bulbs will become more efficient, for example, reducing energy use and cutting the heat generated and the required size of heat sinks. Next, lab researchers will study the amount of hazardous materials in the three types of bulbs mercury in CFLs, for example whether they exceed federal and California and disposal regulations. Energy Star, the federal government s program to certify energy efficient products, warns that LED bulb quality can be spotty and some manufacturers make exaggerated claims. Energy Star s light bulb page includes a list of LED and CFL bulbs that meet its quality standards.
