Roller Mill Grinders

mill grinder typically uses 30-50 percent. For those of you unfamil- iar with roller mills, the basic principal of operation is simple: Two parallel rolls rotate towards one another at high speeds, say 400 –. 3000rpm. Material is gravity fed between the parallel rolls and as it enters the 'nip' of the rollers, it experiences both crushing.

Crushing - Geevor Tin Mine

Reducing the size of the ore particles prior to mineral separation is called comminution; this normally takes place in stages. The first stage is primary crushing; this may be followed by secondary crushing and so on. The last stage of comminution is grinding; this might also be done in several stages to optimise the conditions.

Disc Mill MILLS - mrc
