Abstract. Cylpebs are slightly tapered cylindrical grinding media with a ratio of length to diameter of unity. The manufactures have made conflicting claims regarding the milling performance of Cylpebs in comparison with balls. One major point of interest is which one grinds finer at the same operating conditions.

Analyzing the grinding media shapes (cylpebs versus balls) on the particle size of the mill product showed that cylpebs were slightly tapered and become cylindrical grinding media with a length equaling diameter, and all the edges being worn off. Due to their cylindrical geometry, cylpebs have a greater surface area per volume and higher bulk ...

media shape and mill power. The objective of this dissertation was to investigate how media shape affects grinding. Ball size distribution inside an industrial mill was analysed in terms of shapes and sizes. Load behaviour, mill power and breakage as affected by media shapes were studied in a pilot laboratory mill. An inductive proximity probe ...

In the present study, the effect of grinding media shape on breakage parameters was investigated. Balls and cylpebs were used as the grinding media. It was observed that the grinding of quartz obeyed first‐order breakage kinetics in the case of balls and cylpebs. Higher breakage rates were noted with cylpebs than with balls. Furthermore, it was found that the …

Grinding media shape cylpebs versus balls Mineral. Balls and cylpebs were used as grinding charges for comparison. Quartz was chosen as a reference sample because it follows first order grinding kinetics. It was found that the grinding of quartz obeyed the first order breakage kinetics in the case of balls and cylpebs.

Cylindrical grinding media, which have a slightly spherical shape, called Cylpebs have recently been introduced. Comparative tests have been performed using Cylpebs and balls in a laboratory ball mill under the same conditions of mass and feed. Results show that a faster breakage rate is obtained using Cylpebs as the charge.

A ball mill is partly filled with steel balls (some are cylindrical shaped cylpebs) that impart a tumbling and cascading action when the mill rotates around its horizontal axis. Material fed through the mill is crushed by impact and ground by attrition between the balls. The grinding media are usually made of high-chromium steel or manganese steel.
