Mar 14, 2007· As an engineer who has experience using FEM for the design and assessment of SAG and ball mill foundations, I know that this approach can be timeconsuming, costly and in some cases not even a hope of being accurate if you don't have appropriate geotechnical and manufacturer information.
The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum 'chunk size', product size as P80 and maximum and finally the type of circuit open/closed
Jun 25, 2018· Mill effective diameter = m . 335 is a constant used for dry grinding with steel balls in the mill. Actual size of media is taken is lower than the calculated value. It is around 80 to 90 mm. If you Wants to reduce the maximum ball size, thenreduce the feed size by using pregrinding operation.

Dec 23, 2013· To grind the coarse salt to a smaller size by using a ball mill and to obtain the particle size distribution of the initial and the sieved final mixture. Introduction: 'Ball milling is a method used to break down the solids to smaller sizes or into a powder. A ball mill is a .
Simulation of Size Reduction in Ball Mills and DEM. The mill (with 30 cm in diameter and 30 cm in length) and the test conditions are standardized, with a maximum ball size of 40 mm and an ore top size of mm. With less than 300 balls, it poses no challenge in running the simulations, if .
Ball mill. A typical type of fine grinder is the ball slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.
small scale and large scale capacity. There are various types of machines generally used for size reduction of materials. These are Gyratory crusher. Jaw crusher, Ball mill, Burr mill and many others. Thus, of all the crushing machines available, the Gyratory crusher, jaw crushers and the hammer mill .
