With over 40 years of experience, we have been installing fans in coal mills since the beginning.
If the coal is not sufficiently dried, it will be adsorbed inside the vertical mill and the pulverized coal pipe, which will block the pulverized coal pipe or cause the vertical mill and the pulverized coal pipe to ch fire. Solution: Reduce the coal feed rate, maintain the outlet temperature, and re-check the ventilation control system.
Coal mill is also called coal grinding mill or air-swept coal mill. It is the main equipment in cement plant, which is used for drying and grinding of coal. Big feeding hollow shaft diameter, the ventilation area between the drying bin and grinding chamber is large; the mill tail has no discharge grate, so it has small ventilation resistance.
