coal mill and feeder speeds - func
In most cases, coal mill feeders are smaller than raw mill or finish mill feeders with capacities of 10-100 tons per hour. The #1 issue for coal mill operators is stickiness or coal build-up on all the material handling equipment, including the mill feeder. Raw coal, which is usually 3-4" inches or smaller, can have inherent moisture in it ...

Hammermill and roll crusher maintenance and operation
2023年6月22日 If the mill capacity decreases, or if the motor load does not go up when the feeder speed is increased, it is very likely that the material is not passing through the top pair of rolls. To maximize capacity and extend roll life, open the top pair of rolls slightly and/or reduce the feed rate to eliminate accumulation in the nip of the top rolls.
