Sep 07, 2011· Re: VRM and ball mill circulating load. Mainly in USA, the term circulating load is more often used than the circulation factor.Circulating load is percentage of coarse return in relation to fines & it can be calculated by : Coarse return TPH X 100 / Mill output TPH.Normal range of cirulating load in a conventional close circuit ball mill is around 100-200%.
Overview. The ball mill for clinker is an efficient tool for fine powder grinding. It is mainly used to grind the clinker and raw materials in cement industry and also can be applied in metallurgy, chemical, electric power and other industries to grind all kinds of ores.
In cement production, tube mills having multi-chambers are traditionally used either in open or closed circuit operations. After the introduction of high compression grinding mills (High pressure grinding rolls (HPGR), vertical roller mill (VRM) and Horomill), various circuit configurations have been developed for energy efficient grinding.

Ball Mill Internals Ball mills have been conventionally an integral part of most cement plants for grinding raw materials, coal and clinker. The major technological advancements in conventional ball mills have been the improvement in diaphragm, liners and grinding media. The application of controlled flow
Typically, an electrical motor of the ball mill uses about 14–15 kWh/tonne of raw mix. On the other hand, a VRM motor uses about 7–8 kWh/tonne. On an overall basis, a VRM consumes about 20% lower specific energy than a conventional closed circuit ball mill. A VRM is widely used for raw material and coal grinding in the cement industry. 5.1.3.
Cement Mill Great Wall Corporation. Cement ball mill is an efficient tool for fine powder grinding. It is mainly used to grind the clinker and raw materials in cement industry and also can be applied in metallurgy, chemical, electric power and other industries to grind all kinds of ores.
Upgrading from a conventional grinding system can, in some cases, more than double your production capacity, while also reducing specific energy consumption by 30 percent. In ball mills, for example, less power is required to produce finished cement from Hydraulic Roller Press-pressed material than from un-pressed material.
cement industry the ball mill was really an epoch-making breakthrough as for almost 80 years it was the predominant mill for grinding of raw materials and coal, and still today is the most used mill for cement grinding. Over the last three decades the vertical roller mill has become the preferred mill .
