The crushing is turning the halite ore with 30-100mm to small granule by different levels of processing with halite crushing equipment, eventually becoming the particle size about 2-8mm.This often includes primary crushing, secondary crushing, tertiary crushing and so on. The grinding is making a simple screening for the crushed halite.
