The Ball Mill is designed to grind materials by turning the cylindrical shell with grinding medium (e.g. steel balls, cylpeb, and pebbles) put in the shell, and has a simple structure and ease of handling. Furthermore, The Ball Mill of a large capacity has been available to a very extensive range of applications in both dry and wet processing.
These airlock feeders are used for feeding limestone lumps to raw mills, and coal lumps to coal mills in cement industry to avoid false air entering in to the mill thereby decreasing its efficiency. It is designed to pass hot air through the rotor pockets to reduce moisture in the material, thereby avoiding clogging of material in the rotor ...
Coal mill hot air inlet temperatures should never be more than 600 ° F and the outlet temperature should not exceed 200°F on Raymond coal mills. If the flow of raw coal to the coal mill is interrupted for any reason (for example: plugging, failure of the coal feeder, etc.), the outlet temperature of the coal mill can quickly climb to ...
