Crushing is an important step in the complex process of mineral processing fig. 1. in open pit mines, rock chunks with edge lengths of have to be processed. in underground mines, the biggest chunk sizes are about 0.5 m. crushers have the task of reducing the ore rock to particle sizes in the millimetre range for subsequent grinding.
Crushing is the first step of mineral processing where the orerocks from the mine site is fed into the mechanical equipment in order to reduce the size of masses for subsequent usage by.
For crushing no grinding media is required, the ore size is reduced by external forces applied by the crusher. dry crushing but wet grinding crushing is usuallyry process, while milling is performed with water. the advantage of wet milling is.
Grinding equipment for mineral processing. the final fineness of the product mainly depends on the number of times the ore particles pass through the grinder. the longer the grinding, the smaller the particle size. separate crushing and grinding steps are necessary, the ball mill can only receive the broken ore particle, and then grind to the.
In mineral processing, the reduction of minerals by crushing and grinding may be regarded as having one or other of two main objectives the attainment ofize appropriate for the direct industrial application of the mineral, e.g. barytes, sand, aggregate or the release of metallic or ore inclusions from an unwanted matrix withiew to maximum separation. in both.
