Guilin Hong Cheng Coal gangue grinding mill is the ideal device for coal gangue disposal and recycle

1. The application value of coal gangue grinding mill

Large amount of coal gangue which is a kind of solid waste is discharged in China every year, which is a big threat to the environment; coal gangue crusher and grinding mill with superior performance is the ideal device for coal gangue disposal and recycle.

The comprehensive utilization rate of coal gangue is over 50% in China; the main application of coal gangue is in the areas of electricity generation, building material production, land reclamation, backfill in subsidence areas etc. Coal gangue grinding mill has high application value in the area of coal gangue disposal and recycle, the performance of coal gangue grinding mill has direct impact on the finished products which can be widely used in the downstream industries.

2. Guilin Hong Cheng coal gangue grinding mill’s performance

Guilin Hong Cheng develops coal gangue grinding mill which is the product based on years of R and D to meet the market demand for coal gangue disposal and recycle; its output is 5-700t/h which equals that of 5 traditional ball mills; Guilin Hong Cheng coal gangue grinding mill is equipped with advanced PLC electronic control system which can achieve remote control of the materials and the grinding process; the energy consumption is 40-50% lower, this standard is much higher than the national standard for energy conservation and consumption reduction; it is equipped with new type roller sealing device and pulse dust collector which contribute to 99.9% dust collecting rate.

3. The working principle of coal gangue grinding mill

HLM vertical mill system consists of main engine, feeder, classifier, blower, pipes, storage hopper, electronic control system, collecting system etc.

The pressure device in HLM vertical mill is designed and produced by adopting standard modules, the number of rollers in the mill can be 2,3,4, or 6 at most, and the rollers can be installed by adopting the method of permutation and combination to use the fewest standard modules to  produce multiple series of products, the demand for different fineness  and  output can be met.

The motor drives the reducer to rotate the millstone, the materials which are pushed to the space between rollers and millstone by centrifugal force are crushed, ground and smashed. Then the blower blows the powder to classifier , the large grain size powder falls down to be reground and the fine powder goes into pulse powder collector and is blown out through the pipes as finished product, the purified air is blown out through the pipes  above the pulse powder collector.
