05/07/2020 · A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size. The large balls tend to break down the coarse ...

19/06/2015 · Ball Mill Power Calculation Example #1. A wet grinding ball mill in closed circuit is to be fed 100 TPH of a material with a work index of 15 and a size distribution of 80% passing ¼ inch (6350 microns). The required product size distribution is to be 80% passing 100 mesh (149 microns). In order to determine the power requirement, the steps are as follows: Example Calculation. A motor with ...

It is possible to make an approximate calculation of the capacity of a ball mill by means of the equation: N = ( D 3 L ρ ϕ + L n) 1 η 1 η 2. where ρ is the apparent density of the balls; l is the degree of filling of the mill by balls; n is revolutions per minute; η 1, and η 2 are coefficients of efficiency of electric engine and drive, respectively. A feature of ...

12/04/2021 · Working of Ball Mill: The drug to be ground is put into the cylinder of the mill and is rotated. The speed of the rotation is very different. At low speed, the mass of balls will slide or roll over each other and only a negligible amount of size reduction will occur. At a high speed, the balls will be thrown out to the walls by centrifugal force and no grinding will occur. But at about 2/3rd ...

24/04/2015 · Ball mill consist of a hollow cylindrical shell rotating about its axis. Axis of the shell horizontal or at small angle to the horizontal It is partially filled with balls made up of Steel,Stainless steel or rubber Inner surface of the shell is lined with abrasion resistant materials such as Manganese,Steel or rubber Length of the mill is approximately equal to its diameter Balls occupy about ...

18/09/2020 · ball mill work principle and calculation. Ball Mills Mineral Processing Metallurgy. Working Principle Operation. The apparent difference in capacities between grinding mills (listed as being the same size) is due to the fact that there is no uniform method of designating the size of a mill, for example: a 5′ x 5′ Ball Mill has a working diameter of 5′ inside the liners and has 20 per ...

In Grinding selecting calculate the correct or optimum ball size that allows for the best and optimum ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do Often the ball used in ball mills is oversize just in case Well this safety factor can cost you much in recovery and or mill liner wear and . principles of ...
