Particle size reduction of materials in a ball mill with the presence of metallic balls or other media dates back to the late 1800 s. The basic construction of a ball mill is a cylindrical container with journals at its axis. Chat Online; The operating principle of the ball mill. The operating principle of the ball mill consists of following steps.
Steel balls have a SG of 7.7 and have an average weight/volume of 40 pounds/gallon. Higher density grinding media generally results in faster grinding in a ball mill. An optimum grinding charge for a ball mill may be experimentally determined, however generally the range is from 20% to 50% of the mill volume, or to the center line.
using a drum mill, used to contain a certain ball charge - usually mill filled with balls to 40-50% of its volume. During operation of the mill is periodic therein to add new portions of the balls. The world average cost of balls is about 0,9-1,1 kg for 1t ground ore. …
required to operate a commercial ball mill of radius R is predicted on the assumption that the ball mill is half filled with balls, there is a cascade angle of 45o, and the mill base just covers the top layer Fig.1: Optimum cascading of mill for power consumption of the ball. Let the average density of the ball mill …
The ball mill is a key equipment to grind the crushed materials, which is widely used in the manufacture industries, such as cement, silicate, new building material, refractory material, fertilizer, ferrous metal, nonferrous metal and glass ceramics. Features: 1. Large application range, simple structure and convenient maintenance; 2.
There should be at least 25% empty place in the mill pot after feeding balls and material s. There is no such thumb rule for powder to ball ratio. It is generally decided by nature of materials to b e milled and ball size, ball to material weight ratio, milling time, RPM ,etc

It doesn't look like much, but it works great, and it cost almost nothing to build. As a bonus, this ball mill can also be used as a rock tumbler, or a glass tumbler to make your own sea glass at home. To use the mill as a rock tumbler, just leave out the steel balls, add rocks, tumbling grit and water, and let it spin.
I place the aluminum, the ball bearings, and about 3 to 5% of the weight of the Aluminum of stearin into the rock tumbler and seal it up. I set the tumbler on wooden blocks so that it sits at about a 20 degree angle from the horizontal. This will increase the tumbling action of the steel balls. I run the improvised ball mill continuously
