Ball mills as used in mining, cement production and allied industries consume about 40% to 56% of the total electric power supplied. Electric power losses in ball mill operations constitute about 25% of the available power. This paper reports on investigations into ball mill motor efficiency evidenced from a cement plant operations perspective.

Cement milling is the process of grinding the clinker, a nodular material produced during the cement kiln stage, into a fine powder. The aim of cement milling is to reduce the particle size of the clinker to enhance the cement's performance. The milling process involves the use of a ball mill, a large rotating drum that grinds the clinker and ...

Vertical Roller Mills (VRM) have a clearly higher energy efficiency than ball mills, even if the ball mill is combined with a roller press. This and further arguments led to the increased share of VRM for the grinding of finished cement. Taking into account that VRM usually have a bigger output than ball mills, it can be declared that the major ...

suit all mill OEM's. Key benefits. Cement grinding. The feed for a cement grinding unit will normally be dry and. needs to be ground to a high degree of fineness. To achieve this efficiently, most mills will be split into two chambers. The first is set up for coarse grinding with a target to grind the feed materials down to around 1 mm.

A 10 MW cement mill, output 270 tonnes per hour. A cement mill (or finish mill in North American usage [1]) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement. Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
