#### Ball Mill Application and Design Paul O. Abbe

Ball mills are simple in design, consisting of horizontal slow rotating vessels half filled with grinding media of ¼” to 1.5”. The particles to be milled are trapped between the grinding media or balls and are reduced in size by the actions of impact and attrition.Size reduction of material using ball mill Labmonk,Run the ball mill for 30 minutes at a speed of 1 rpm. After 30 minutes take out rice powder from the ball mill. Fill the rice powder to a new set of sieve of smaller sizes. Weigh the mass of rice powder retained on each sieve.

The design results show that the minimum shaft power required to drive the ball mill is 0.2025 horsepower, the length of the mill at a fixed mill diameter of 210 mm is 373 mm, and the required shaft length and diameter are 712.2 mm and 30 mm respectively.Ball mill Wikipedia,It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the shell may be either horizontal or at a small angle to the horizontal. It is partially filled with balls.

Size Reduction Resource Center. Steel Ball Mills. Benefits of Tumble Milling: 1. HIGH EFFICIENCY Slice Mills™ are identical to the Ball Mills and Ceramic Lined Mills in diameter and design The only difference is that they are as little as 12” in length.Ball Mill: Operating principles, components, Uses,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 feed materials and the smaller balls help to form fine product by reducing void spaces between the balls. Ball mills grind material by impact and attrition.
