OK mill and the retention time in the mill is shorter, the product will not be heated up as much as in a ball mill. This means that a lower degree of dehydration of the gypsum must be anticipated. This may not be a problem if the gypsum is sufficiently reactive to control the setting reactions, which is normally the case. If in special.A ball mill is a grinding machine used to grind, blend, and sometimes for mixing of materials for use in geology, ceramics, metallurgy, electronics, pharmacy, construction material, and light industry, etc. Ball mills are classified as attritor, planetary ball mill, high energy ball mill, horizontal ball mill.
