grinding for coarse ore

Iron ore grinding process,process design for grinding stage Because the ore to be ground passes through the grinding machine only once, the product size is relatively coarse. This type of process is commonly used in the first stage of the singlestage rod milling process or the first stage of the twostage grinding process with rod mills. The ore can be ground from 2025 mm to about 3 mm at a time.

Mineral processing Crushing and grinding are the two primary comminution processes. Crushing is normally carried out on "runofmine"ore, while grinding (normally carried out after crushing) may be conducted on dry or slurried material. In comminution, the size reduction of particles is done by three types of forces: compression, impact and attrition.
