The screening process serves to separate particles of different sizes and is ideal to ensure that the product reaches the market in the right size, shape and quality. In aggregate production, the screening process is a key part of the production process and is carried out on a large scale. Therefore, it is necessary to make sure that the ...

Crushing is the process of size reduction of ore. Size reduction process begins with usage of explosives at the area for production of ore. In later stages, the size reduction process performed with crushers before grinding in mills is called "crushing". Although there is no limit set, the downsizing process over 3 mm is considered as "crushing ...

Crushing 'Comminution' is the term used to define the process that reduces materials (especially mined ore).It is the action of reducing a material to minute fragments or particles.The process is typically achieved in mining operations through stages of crushing and milling. In the past, mining activities were arduous and labour intensive.
