Crusher Coal production line has played an important role, currently, most of China's Coal production line there are old-fashioned equipment, such as old-fashioned coal preparation, coal equipment, set of old-fashioned broken equipment low yield, and energy consumption, cost of production greatly improved, and how to be able to solve the current status quo, adopts new stone crusher has such improved in the new design of the crusher machine and coal preparation machinery and efficient coal preparation technology is old-fashioned PREPARATION machine can not reach, is also a replacement of the old-fashioned coal preparation technology products.Large, efficient, durable coal preparation equipment, has become an indispensable part of modern coal mine production resources. Western countries Coking coal has ash requirement is 5% to 8%. Provisions of the United States are not allowed to use more than 1% of the elemental sulfur thermal coal power plant.
Therefore, both coking coal and steam coal, must carry out the washing or screening. Germany, Britain, France, Japan and other countries of raw coal almost all were selected, the selected raw coal in the United States is a low-ash thermal coal, but also for screening, large pieces of waste rock removed by selective crusher. The jigger and heavy media separation machine processing capacity has reached 1000 tons / maximum flotation machine 50 t / h. Germany of Haili Xi Robert mine new coal washery, using a combination washing system, each process only with a set of large equipment, no spare, greatly simplifies the entire process. The main device only with a lump coal jig and a specially coal jigging machines and a 400 t / h centrifugal dewatering machine.
