Given the size and type of particles that need to be pumped by a mill circuit pump, erosive wear is one of the most critical design considerations. Unlike some mill pumps that only last up to 500 hour cycles (due to the extreme wear experienced), our ® MC pumps can achieve over 5,000 hour cycles in SAG and ball mill applications.

Ball mills operate on the principle of impact and attrition: in the operation of the mill, the grinding media in the mill throw itself against the material to be ground to produce fine particles. This process is used to reduce the size of the ore to the necessary extent before proceeding, for instance, to flotation or magnetic separation.
