Coal Grinding Mill
Coal Grinding Mill process
1. The raw coal is sieved from the raw coal yard through the grid screen and then dropped onto the belt conveyor. After the iron remover is removed by the electromagnetic separator, the belt conveyor feeds the raw coal into the original coal bin for storage.
2. After the powder preparation system has been started, open the rod valve at the bottom of the original coal bunker, start the sealed metering tape to the Coal Grinding Mill, and the raw coal enters the Coal Grinding Mill for drying and grinding.
3. The hot air from the hot blast stove or the waste gas from the cement production line enters the Coal Grinding Mill under the extraction of the system fan, and after the heat exchange with the ground coal that is ground in the mill, the pulverized coal is taken at the separator. Sorting, the fine coal powder with unqualified fineness falls to the grinding disc for grinding, and the qualified coal powder is collected into the explosion-proof gas box pulse dust collector with the airflow, and is discharged into the coal powder bin through the dividing wheel.
4. The sundries in the raw coal, such as some coal gangue, metal blocks, etc., are discharged through the wind ring and the spit slag.
The Coal Grinding Mill uses a grinding roller to directly grind the grinding material on the grinding disc. The grinding efficiency is high, the energy consumption is small, the system power consumption is only 18~22 kWh/t, and the output is guaranteed.
The Coal Grinding Mill adopts advanced dynamic and static combined separator. The separator has high classification efficiency and large adjustment room. The fineness of powder selection can reach below 3% of 0,08mm sieve, which can meet most of the poor quality coal in cement production line or Fineness requirements for anthracite grinding.
