工作原理

　 The materials fall down via the discharge chute in the center of grinding disc, which rotates at constant speed distributes evenly the materials outwards by the centrifugal force to form the materials bed with a certain thickness to be crushed then by the grinding rollers. Next the material move under the continuous centrifugal force, forwards to outer edge of the disc. After ground the materials leave the disc, lift with the hot air prior to be fed in the mill, and enter into the separator through the mill center. During this process, the full heat exchange has been completed between the materials and hot air in order to evaporate quickly the moisture.

　　The separator determines the product granularity from the roll mill. The sizes over the specified ones will be separated and returned back to the disc for regrinding, and the sizes which meet the fineness requirement will be sent to the collector and then to the product silo.
