This is only for the discharge head, grates and pulp filters (rubber). A comparison in laboratory of Overflow Discharge Ball Mill VS Grate Discharge Ball Mill.
WhatsApp: +86 18838072829A mill is a device, often a structure, machine or kitchen appliance, that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (, via a hand crank), working ...
WhatsApp: +86 18838072829For one, the ball charge and tumbling motion of a Bond mill is inefficient in this range. Also, screening well at 500 mesh is not easy. Many people overlook the impact of screening on the Bond results but the impact can be significant. The other issue is that nowadays fine grinding is not performed in tumbling mills for energy efficiency reasons.
