Grinding mills are essential equipment for this purpose as they efficiently grind down crushed ore using various mechanisms. One type of grinding mill commonly used in hard rock gold mining is the ball mill. This cylindrical device rotates around its axis and uses steel balls or other grinding media to pulverize the ore inside it.

The dried material is fed to the ball mill for grinding. Concentrate/ground iron ore of typical size 80 % less than 45 microns (0.045 mm) with a moisture content of around 9 % is required for the pellet production. Suitable binder (normally bentonite) is added to the concentrate which is thoroughly mixed in high intensity mixer.

In addition, if the operating parameters such as ore size, type, charge, etc., change, the evaluation may lead to the wrong conclusion as to which type of balls are best (Avery, 1961). Small-scale ball mill tests are convenient but could give misleading results because they do not produce the severe ball impacts of full-sized mills.

There are two "inputs" to a ball mill circuit: the ore fed to the circuit and the power delivered by the grinding mill. A ball mill circuit has two "efficiencies": that of the ball mill grinding environment* and that of the classification system*. A ball mill circuit has two efficiencies because it has two main functions:

A ball mill is a form of grinder that is used to blend or grind materials for use. It is a cylindrical device mainly for grinding material such as iron ores, ceramic raw materials, glass, steel, etc. The ball mill works on impact and attrition principle. Its impact is the size reduction given that the balls drop from almost the top of the shell.
