Most customers choose the type of equipment based on the type of material so that it can operate more efficiently. The types of materials include crushability and relative density. The pulverization of materials has a great influence on the disposal level. Usually, the type of pulverizer is determined based on the specific effect of disposing similar materials. Usually, when selecting machines, enterprises choose the pulverization effect obtained from the test. The utility coefficient of the raw material is obtained by the power consumption of the pulverizer to process one ton of material.

Then, determine the product specifications of the required equipment. The situation of the material is mainly only the dry humidity and temperature of the material. Unlike oily grinding, in dry grinding, if the moisture content of the material exceeds, the disposal level of the grinder will drop sharply, especially in dry ball mills. When dry grinding is used for lubricating materials, the materials must be dried beforehand to keep the moisture content below.
