Grinding Circuit

Apr 25, 2016 In a simple grinding circuit there will be a ball mill and a classifier. Some circuits, especially in large mills, have more units or two or three stages of grinding, but whatever is said here will apply to the complicated circuits as well as the simple ones. The two types of ball mill in general use are the grate mill and the open-end mill

    AMIT 135: Lesson 6 Grinding Circuit – Mining Mill Operator

    Grinding is a powdering or pulverizing process using the rock mechanical forces of impaction and attrition. The two main objectives for a grinding process are: To liberate individual minerals trapped in rock crystals (ores) and thereby open up for a subsequent enrichment in the form of separation
