IV. BALL MILLS Ball mills are one of the more common mills and use a closed cylindrical container that is rotated horizontally on its axis so that the media cascades. A typical ball mill has an L/D ratio of 1.5:1. Ball mills are filled with spheres or other shapes made of steel or ceramics; or with pebbles made of flint (or of an ore being ground).
A dynamic model is developed for a wet overflow ball mill based on a set of mass and energy balances to simulate the mill. The energy balance relies on temperature and mass flow data. The key control parameters to be measured are mill temperature (feed and discharge streams), mill power draw and the mass flow rate in the feed stream.
— Reason: This is a common problem mining ball mills face, resulting in low productivity and low ore processing efficiency. One reason may be the improper design of the grinding chamber, which affects the flow of materials and reduces grinding efficiency. Additionally, worn or damaged liners can hinder the grinding process by reducing the …
