Problems based on Size reduction 1. A certain crusher accepts a feed material having a feed size of 19 mm and gives a product of 5 mm. The power required to crush 15 tones per hr is kw. What will be power consumption if the capacity is reduced to 12 tones per hr with same feed and product size? The mechanical efficiency remains unchanged. Assume that the Rittingers law is applicable ...
These mills are required to prepare ball mill feed. With pebble milling the pebble portion of the product does not go thru the rod mill thus the rod mill feed rate is reduced by 30 metric tonnes per hour (6% of 500 metric tonnes per hour). 2062/500 x 470 = 1938 HP. 1938 ÷ 2 = 962 HP

They are proven workhorses, with discharge mesh sizes from ~40M to <200M. Use of a ball mill is the best choice when long term, stationary milling can be justified by an operation. ... A desired throughput in tons per hour, and a discharge particle size must be specified to properly select the right ball mill for your operation. Pricing. 4' x 8'
10) Find the critical speed of ball mill, if diameter of mill is 800 mm and diameter of balls is 80 mm. 11) A screen of 10 mesh size made up of cm thick wire is used for size separation. The ratio of overflow to underflow obtained is The analysis of two fraction show the overflow contains 89 % oversize material
other methods. The ball mill correction factor (CFnet) is empirical and one way of estimating it was presented by Amelunxen at the Procemin 2013 Short Course by Doll Amelunxen. The SGI equation uses a transfer size between a SAG and ball mill; it is proposed that a synthetic transfer size of 2100 µm be used to model singlestage SAG mills. ˇ

The ability to simulate the Bond work index test also allows examination of truncated ball mill feed size distributions on the work index. For grinding circuits where the feed to a ball mill is sent directly to the classifier and the cyclone underflow feeds the ball mill (see Figure ), a question arises as to whether this practice will alter the ball mill work index (BW i) of the material ...
