Coal mixture temperature is too high risk of explosion, so the process of milling equipment in the operating temperature will rise, so there is a certain security risk.Open single-pulse dust collector system, the device temperature control at 40 ℃, the temperature of the pulverized coal combustion conditions, the loss of, equipment, safe and reliable operation.Designed system include: the system of raw materials into the bucket elevator by raw materials warehouse, by weighing, in addition to the lock after iron into the wind with a belt feeder, into the mill for raw materials as much as possible without strings wind.Products with a single pulse dust collection to complete, reducing the number of equipment units to simplify the system configuration.Products collected by a screw feeder bucket elevator into the storage bin.Into the grinding mill may be drying wet materials.The system is set drying, milling, powder collector, dust in one, safe and convenient.

Coal preparation according to the different customer groups can be divided into two situations:

1. pulverizers used for large thermal power plants, steel mills, chemical plants
Pulverizers is the working speed is 50 ~ 300r/min the mill, blast furnace materials preparation process is professional equipment, medium-speed coal mill system for blast furnace to provide suitable supporting material – coal. Pulverizers for grinding coal, bituminous coal and lean medium hardness of the material powder milling operations, can be widely used in electric power, metallurgy, building materials, chemical industry, milling system, in particular the need to use a large number of bituminous coal The pulverized coal injection coal pulverizing system.

2, T-type pulverizer coal preparation applied to individual enterprises. Design and development for small and medium customers a medium speed trapezium mill, the mill has a low investment, low energy consumption, large capacity, secure, reliable, technical specifications and other advanced features. There are MTW138, 110 and MTM160, 130,100 series of medium-speed T mill, the capacity to solve in less than 15 tons of industrial configuration. After using the first dry milling process, causes the drying of coal in the feed after the high temperature cooled before grinding to prevent because the heat caused by explosion. Milling system before the cyclone powder collector, and a switch from pulse bag filter dust, powder and dust collection to achieve integration, to ensure a clean environment milling workshop.
