on 70% of the coal passing through a 200 mesh screen. Mills are capable of grinding harder coal with higher percentage moisture content and can reduce the product fineness in excess of 90% passing a 200 mesh screen at a reduced output capacity. The feed size of the coal to the mill should be pre-crushed to 1" top size. Available capacity size

Handles all types of coal. The durable grinding mill can handle virtually any type of raw coal and has been designed to grind feed materials with varying moisture levels. The ATOX® Coal Mill handles feed materials with less than one percent moisture and up to 25 percent moisture, where abrasiveness and stickiness is not an issue for grinding.
The gravimetric feeder compensates for the variation in bulk density and feeds a fixed weight of coal in response to a boiler fuel demand. This ability to accurately weigh the coal provides significant improvement over volumetric types in terms of matching the fuel delivered by the feeder to the actual process energy required on coal fired units.
