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 ...

2015-04-24· • Weight of the balls: With a heavy discharge of balls,we get a fine product.We can increase the weight of the charge by increasing the number of balls or by using a ball material of high density • Speed & rotation of Ball mill: low speeds,the balls simply roll over one another and little grinding is obtained while at very high speeds the balls are carried along the walls of the shell and ...

Ball mills normally operate with an approximate ball charge of 30%. Ball mills are characterized by their smaller (comparatively) diameter and longer length, and often have a length 1.5 to 2.5 times the diameter. The feed is at one end of the cylinder and the discharge is at the other.

As a thumb rule powder to be milled should be taken as 25% of total ball weight. If the quantity of charge is very less then milling balls will start to collide with each other and no milling will...

Number, size and mass of each ball size depends on mill load and whether or not the media is being added as the initial charge. For the initial chargin of a mill, Coghill and DeVaney (1937) defined the ball size as a function of the top size of the feed, i.e., dâ†"V = 0.40 KâˆšF dB = ball size (cm)

The sizing of ball mills and ball milling circuits from laboratory grinding tests is largely a question of applying empirical equations or factors based on accumulated experience. Different manufacturers use different methods, and it is difficult to check the validity of the sizing estimates when estimates from different sources are widely divergent. It is especially difficult to teach mill ...

We can calculate the steel charge volume of a ball or rod mill and express it as the % of the volume within the liners that is filled with grinding media. While the mill is stopped, the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill.

For overflow ball mills, the charge should not exceed 45% of the mill volume . For grate discharge mills, the charge should occupy about 50% of the mill volume . Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, He, and the radius of the mill, R, i.e.,

2014-03-01· Though, there are small differences in the mill speed (N: 0.6 versus 0.7) and ball load (J: 0.5 versus 0.4), in our opinion the main factor is the ball size distribution: a single size ball charge versus a ball charge made up of balls of three different sizes. The void space in the ball charge, the relative movement of different layers of balls and the type of breakage events generated are ...
