Ball mill capacity tends to increase with larger circulating loads, but this increase is restricted due to limitations in classifiion efficiency. Classifiion efficiency is defined as the percent of final product size material recovered to the classifier fine stream. In literature, there are several studies investigating the effect of classifiion efficiency and circulating load on ...
A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the ...

the mill is used primarily to lift the load (medium and charge). Additional power is required to keep the mill rotating. Power drawn by ball, semiautogenous and autogenous mills A simplified picture of the mill load is shown in Figure Ad this can be used to establish the essential features of a model for mill power. The torque required to turn the mill is given by Torque T Mcgdc T f ...

Decrease The Circulating Load Ball Mill Pdf. In practice, circulating loads between ball mills and classifiers are rarely less than 200 per cent and frequently exceed 700 per cent. It may appear strange at first sight that the circulating load between a mill and classifier producing, for example, 100 tons of finished product per day can be as much as 400 tons or more, but this will be ...
Calculate Ball Mill Circulating Load Pdf. Ball Mill Circulating Load Mineral Processing Metallurgy. The operator will usually sharply reduce the feed rate when actually an increase in dilution water at the feed end of the mill will lower the mill viscosity and allow operation at the higher circulating load
Actually with the recirculating load of about 250300%, your operations are fine on the ball mills. You only experience high recirculating loads if there is a change in the material being treated meaning the Bond work index tends to be higher for the new material. If the new material has a high bond work index then you have to revisit your design criteria as well as the throughput. There is ...
