As one of the commonly used mineral processing equipment, the quantity and proportion of steel balls in ball mill barrel not only affect the grinding efficiency and production capacity of ball mill, but also affect the ball mill's service life.. In the operation process, grinding efficiency of ball mill generally depends on the sum of the work done by each steel ball (the number of steel ...

Therefore, large feeding sizes will affect ball mill efficiency. 3. Mineral slurry density: in wet grinding, material pass time, production efficiency and ball mill power are all influenced by mineral slurry density. Generally speaking, the suitable density is close to 80% when feeding size …

When the proportion of pebbles in the mill charge was low (up to 30%), the larger pebbles wore away significantly faster than expected, based on a constant surface wear rate. This could be due to size segregation in the mill. CITATION. Nkwanyana S and Loveday B. Addition of pebbles to a ball-mill to improve grinding efficiency.

Mar 08, 2013· calculation of ball mill grinding efficiency. dear experts . please tell me how to calculate the grinding efficiency of a closed ckt & open ckt ball mill. in literatures it is written that the grinding efficiency of ball mill is very less [less than 10%]. please expalin in a n excel sheet to calcualte the same. thanks. sidhant. reply

Dec 26, 2017· Several factors affect the efficiency of a ball mill for cement grinding. In this article, we shall be looking at some of these factors that have been proven to influence grinding efficiency: Mill Geometry And Speed. According to Bond (1954), the grinding efficiency of a mill depends on the ball mill diameter, size of the media and mill speed.

There, the effect of a trunnion magnet system on the ball mill was significant: Total mill feed remained essentially unchanged, averaging approximately 1,300 t/h; however, total mill power consumption dropped 8% from an average of 7,600 kW to 7,000 kW. The mill work index dropped 10% from an average of 5.5 kW-hr/T to 5 kW-hr/T.

Enhance the barrel volume can improve the ball mill working efficiency. Ordinary alloy liner plate has thick thickness and large weight, which reduces the ball mill volume and increase the power consumption, lower the working efficiency. Therefore, the liner plate quality is very important, ZGMn13 liner plate is the suitable choice.

The implication of this data is that a build-up of scats in the ball-mills will cause the circulating load to increase in a closed ball-mill circuit, despite the presence of trommels. Table 3.2.2 . Effect of scats particles on ball-milling - Particle size distributions (4 kg of 19/13.2 mm scats added in the feed for the tests of ball-milling ...
