Grinding media. Grinding balls are only one type of grinding media. Grinding media are the means used to crush or grind material (cement, mineral, ) in a mill. Grinding media sorting is performed when the ball load wears out. New grinding balls are then added or full reload is carried out to keep optimum filling degree

In order to reduce the manufacturing costs for cement, it is very important to optimise the existing mill installations as far as the grinding process is concerned and also to use high quality spare parts and consumables like grinding media . Ball mills are predominantly used machines for grinding in the cement industry.

The ball charge mill consists of grinding media in various sizes to ensure optimum grinding efficiency and easy maintenance. The size distribution of the grinding media in the coarse grinding compartment is designed to just crush the coarsest particles in the mill feed material and to ensure adequate fineness of the material

Increases in the ball charge distribution and surface hardness of grinding media and wear resistant mill linings have shown a potential for reducing wear as well as energy consumption. This practice can reduce the grinding energy use by 5- 10% in some mills, which is equivalent to estimated savings of 3-5 kWh/t cement.

Cement clinker is usually ground using a ball mill. This is essentially a large rotating drum containing grinding media - normally steel balls. As the drum rotates, the motion of the balls crushes the clinker. The drum rotates approximately once every couple of seconds. The drum is generally divided into two or three chambers,

The cement industries are using the most diverse range of grinding media, ranging from 17 mm to 90 mm, which is divided in the 2/3 chambers. De- shaped balls are like dead balls, which do not assist in effective grinding, and tend to slide as they move up the periphery of mill, instead of falling or toppling from the top.
