The moisture factor, kM, has little effect on primary crushing capacities in jaw crushers and could be neglected. However when clay is present or the moisture content is high (up to 6%) sticking of fine ores on the operating faces of the jaws is promoted and will reduce the production rate.
Mobile crushers Metso Outotec
Mobile crushers are often referred to as ‘mobile crushing plants’. They are track-mounted crushing machines which, thanks to their mobility, can maximise productivity and reduce operating costs while increasing safety and reducing environmental impact.
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.
