Cement manufacturing - brief description of a cement mill. 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, with ...

Dry grinding is only used when water is scarce or it is important not to wet the material to be ground, as in the case of Portland cement or kitchen salt, or when there is an attempt to minimize the contamination of the grinding product by the iron debris from the grinding media and liners. The addition of water to form the slurry helps moving the ore inside the mill, dissipates heat from the ...

01.11.2017 · re Cement Mill Grinding Media. Dear Sagarhbt, Why are you concerned about surface area? I never hear about basing your ball charge on surface area! In your first compartment the grinding is not related to surface area at all and it is related to weight and number of impacts. In the second compartment the grinding is related to pass of contact or length of circumference (see attachment). .

The total wear of grinding media, during the cement clinker (balls of forging steel and hardened with 600 Brinell, and cylpebs by special iron) is of 162 – 308 g/t of cement (4.4 – 8.4 g/kWh) [2]. The presented values show a rapid wear of grinding media, which leads to the diminution of specific charge, with negative effects on grinding process. The throughput of the mill is reduced with 4 ...

According to Bond (1954), the grinding efficiency of a mill depends on the ball mill diameter, size of the media and mill speed. Ball mills with different length to diameter ratios for a particular power rating will produce different material retention times. The longer units are used for high retention ratios while shorter units are used where overgrinding is a factor to be considered.

AV: Well, looking at grinding media we run into situations where the media is too large for the expected grind. The result ends up being high wear rates to both the liners and the media and a very inefficient use of energy. You can also run into poor quality media that splits or else wears in a way that results in disk shaped media that does not roll as it should within the mill. This media ...
