In present autogenous grinding abrasion is usually the main reduction mechanism, and the impact and attrition processes may even be detrimental to the grinding operation. The ore feed to an autogenous grinding operation typically consists of ore pieces from 10″ size and downward with 50% coarser than 3 – 4″ and only a small amount, say 10 ...
Keep ReadingThe grinding performance is related to the ball motion in a drum (pot) during milling and is dependent on operational conditions such as rotational speed, ball filling, mill size and sample charge. Especially in wet milling, solid concentration and viscosity of a slurry in a pot are significant parameters for determining optimum condition, .
