Then in ballwear formula (25), T = /K Log10 Da/Db; but from (29), K = Rt/Wt. Then T = /Rt Log10 Da/Db T is 1 day, Wt is the original weight of the ball charge, and Rt is the ball wear for one day. Then Log10 Da/Db = Rt/ are all known, and it is only necessary to solve for Db, the diameter of the balls to be added.

The OK™ mill has been FL's standard cement VRM since 1993. Since its introduction the OK mill has proven to be the most efficient cement VRM available with the highest reliability and ease of operation. In 2017, FL introduced the OK raw mill, which is designed with the same proven technology and modular design as the OK cement mill.
Abstract: The utilisation of coal in the cement and concrete industries takes three basic forms: 1. As a fuel in the production of cement clinker, 2. Ash produced by burning coal in power stations is used as a component in cement rotary kiln feeds, 3. Ash produced by burning coal in power stations is used as a mineral additive in concrete mixes.
Mill wear patterns will tell you a lot about how the mill is performing. General Guidelines When drill pipe is cemented inside and out, a junk mill is the only tool that will do the work.
The increased metal wear of grinding media and mill liners for wet grinding equalizes the additional energy costs of the dry grinding procedure. When dry grinding cement raw material, a protective coating of ground material covers the mill liners and grinding balls. It is known that cement raw material is much less abrasive than cement clinker.
