With the country's attention to environmental issues, in the coal problem has begun to use special fuel pulverized coal equipment. The quality of coal is not only related to environmental issues, but also related to the most important is the return on investment for manufacturers of the problem.Chaeng(Great Wall Machinery) for domestic grinding production equipment, "a vertical mill, eight services," the overall program, at the same time according to market demand for coal mill dedicated history of coal mill.

Because the coal powder fineness, the pulverized coal concentration, the aerosol concentration of the aerosol mixture, the temperature, the velocity of flow, the humidity and so on will affect the coal powder combustion the security. Therefore, in the selection of pulverized coal equipment in addition to the host when the energy efficient equipment, environmental protection, the auxiliary system must meet the requirements of fire and explosion and automatic operation.

The machine is a kind of pulverized coal preparation machinery widely used in cement building materials, chemical industry, coal, electricity and other departments. The main features are mature technology, superior performance, with its small footprint, simple process, compact layout, low energy consumption and low noise, and set crushing, grinding, drying, powder, transportation and many other advantages.

Raw coal from the coal yard through the lattice sieve screen after the fall on the belt conveyor, the electromagnetic iron separator iron, the belt conveyor to coal storage for raw coal storage. After the grinding system has been started, open the bottom of the original coal bunker valve, start measuring the tape to the vertical coal mill, coal into the vertical mill for drying, grinding. Hot air from the hot air furnace or cement production line emissions, in the system fan drawing, into the coal vertical mill, grinding and grinding of raw coal to fully heat exchange, with the coal powder at the separator at the separation , Fineness unqualified coarse coal powder fell again on the grinding disc, qualified coal with air into the explosion-proof gas tank pulsed dust collector was collected, after the grid into the coal storage compartment. Raw coal in the debris, such as part of the gangue, metal block, through the wind ring, spit residue mouth out of grinding. At the same time the whole system of nitrogen system and carbon dioxide fire extinguishing system to provide explosion protection and fire protection, the key components installed explosion-proof valve.

Chaeng coal mill also has a unique structural features:

1, coal vertical mill with a disc-shaped disc and the tire-shaped roller sets, more suitable for coal grinding.

2, roller bearings without special sealing. Roller device uses a pair of spherical roller bearings, bearing seal cavity extends to the case, not with dust-laden gas contact, so long as a simple seal can make roller bearings do not enter the dust, do not need sealed fan.

3, mill transmission part, do not need auxiliary transmission device.

4, slagging part of the simple. Coal vertical mill less slag, slagging mouth with a cover, do not need to install slag discharge valve.

In the Chaneg for more than 50 years of grinding equipment preparation process has a wealth of experience in the majority of customers enjoy a high reputation. Welcome to the new and old customers to visit the Advisory!
