Crushing & Grinding Circuit Design - Comminution
(Fig. 1) From this circuit, complexity increases to multi-stage crushing circuits preparing feed for multi-stage grinding circuits. Fig. 2 showing a three stage rod mill ball mill arrangement is an example of a complex grinding circuit. Stage concentration further complicates the flow.
COMMINUTION: Liberation, Crushing, Grinding
Comminution in the mineral processing plant takes place in a sequence of crushing and grinding (and/or milling). Crushing reduces particle size of run-of-mine ore to such a level that grinding ...
Comminution - Wikipedia
Comminution is the reduction of solid materials from one average particle size to a smaller average particle size, by crushing, grinding, cutting, vibrating, or other processes. In geology, it occurs naturally during faulting in the upper part of the Earths crust. In industry, it is an important unit operation in mineral processing, ceramics, electronics, and other fields, accomplished with many types of mill. In dentistry, it is the result of mastication of food. In general medicine, it is one of the most traumatic forms of stone fracture.
Difference between Crushing and Grinding
When making comparisons of the efficiencies of different grinding and crushing machines it is desirable to be able to estimate the work actually done in crushing the ore from a given size of feed to a given size of product, the screen analysis of both feed and product being determined. Messrs. Klug and Taylor, in a stone on this subject, published in the monthly journal of the Chamber of Mines ...
