اقرأ أكثرA crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.
اقرأ أكثرThey also enable efficient reporting, continuous improvements and minimization of major plant upsets. Mill circuit isolation is another area challenged with maintaining optimized grinding mill performance and reliability to ensure a tight shutoff. Excessive valve wear and equipment failures lead to increased planned and unplanned shutdowns.
