Raymond Mill can be used to grind many kinds of raw materials into fine powder, but the Raymond Mill performance is influenced by the humidity of the raw material significantly.

For the Raymond Mill, the humidity of the raw material usually should be less than 6%, but for some material such as limestone the humidity can be up to 10%. If the raw material humidity is high, then we need to use the rotary dryer machine to dry the wet material in advance before it come into the Raymond Mill.

Raymond Mill by Dingli Machinery ismainly used to grind and process variety kinds of non-flammable and non-explosive materialswith hardnessless than 7 and humidityless than 6% in mining, construction, chemical industry, etc.Raymond Grinding Millis ideal grinding machine to grind and process the materials such as limestone, gypsum, barite, carbonate calcium, marble, feldspar,dolomite, granite, kaolin, bentonite, bauxite, etc.

The powder fineness of Raymond Mill can be from 40 mesh (0.614m) to 325 mesh (0.044mm), and some fine powder even can be up to 1000 mesh (0.013mm).
