There are plenty of factors that affect the capacity of grinder. (AKA the grinding quantity, unit: ton/hour) the following five factors are the most common factors that influence the grinding capacity:

1. The hardness of raw materials. If the hardness is high, it is difficult to grind. Micro powder grinding mill from Shanghai Clirik Machinery Co., Ltd is applied to non-inflammable, non-explosive and brittle materials with Mohs'''''''' hardness under six, such as calcite, chalk, limestone, dolomite, kaolin, bentonite, talc, carbon black and so on.                    

2. Output size (or finished size, final size): the smaller of the output size, the lower of the production capacity. The output size from our HGM series grinding mills can be freely controlled between 325 mesh and 3000 mesh (or 5-47µm), and the capacity ranges from 0.4 T/H to 7.5 T/H.

3. The humidity of the grinding materials. If the raw materials contain high percent water, the materials will easily adhere to the surface of the grinding mill and block the grinding speed. Thus, water content should be strictly controlled if higher capacity is needed.

4. The composition of the grinding materials. If there is much powder in the raw material, it may reduce down the capacity since the powder will easily adhere. The content of powder should be screened before crushing. Besides, the density of the raw materials can largely affect the final capacity, light materials will absolutely have smaller capacity, such as petrol coke.

5. The quality of quick wear parts (such as hammer mill, grinding rollers). If the quick wear parts have no good abrasive resistance, it will decrease capacity in the long run.
