The ball mill consists of a metal cylinder and a ball. The working principle is that when the cylinder is rotated, the grinding body (ball) and the object to be polished (material) installed in the cylinder are rotated by the cylinder under the action of friction and centrifugal force. At a certain height, it will automatically fall and impact ...

A grinding mill (Ball Mill) is used to grind the cement clinker into fine cement powder. Grinding Aids are used to improve the grinding efficiency and reduce power consumption. This paper discusses the grinding aids mechanism and improvement in grinding efficiency due to various grinding aids viz .polyols, amines .

The invention relates to the use of methyldiethanolamine as a grinding aid for cement, and in particular its use as a strength enhancing grinding aid for cement. The compressive strength may be enhanced by the methyldiethanolamine at both at an early stage (1and/or 3 days from the start of hydration) and at a late stage (7 and/or 28 days from the start of hydration).

The researches of Schweitzer and Craig into the grinding of cement clinker, in a laboratory ball mill, with carbon black as a grinding aid show a continuous increase in the rate of grind, or fineness attained in a given time, for additions up to about 1 % by weight of the feed.

Grinding Balls. Steel balls ranging from ¾ to 5 in. in diameter are used. Rods range from 1½ to 4 in. in diameter and should be 3 to 4 in. shorter than the inside mill length. Tube mills are usually fed balls smaller than 2 in., whereas 4- or 5-in. balls are more commonly used for ball-mill grinding.
