Cement consists of clinker, gypsum and other components mostly more easily ground than clinker. To minimise overgrinding modern ball mills are fitted with dynamic separators (otherwise described as 'classifiers' or more simply as 'separators'). The working principle is that cement is removed from the mill before overgrinding has taken ...

RRSB, cements from ball mills generally have a rather low slope [n']. In a VRM the grinding takes place by pressure and shear force. The clinker passes within seconds between roller and table. The energy input to the material during one passage between grinding rollers and grinding track is relatively low. The thick

This study investigated the effect of grinding media on the finegrinding performance in the wet tumbling mill. Comparative experiments between cylpebs and ceramic balls were conducted in a laboratory wet ball mill under various conditions, such as different total masses, total surface areas, and total numbers. The results indicated that ceramic balls produce a slightly smaller instantaneous ...

Ball Mill: In some cement plants, a ball mill is used to grind clinker into a fine powder. It relies on the use of steel balls to crush and grind the clinker. Ball mills are often used for grinding cement clinker into a fine powder before it is mixed with other materials to produce cement.

The distance traveled by the plunger in absorbing the kinetic energy of the ball and transmitting it to the clinker varies with the particle size and quantity of sample. The relations between this distance and the time of impact are the probable cause of differences in the amount of the energy correction. ... A mill grinding such a material ...

Ball mill grinding was carried out by using a laboratory scale mill, since it was impossible to get clinker only samples from an industrial ball mill because of gypsum addition during the grinding process. Gypsum in clinker was not preferred for liberation analysis since it makes the mineralogy complex.
