comparison of grinding media cylpebs versus balls

Comparison of grinding media—Cylpebs versus balls

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. The difficulty in comparison is due to the shape difference. The two grinding media have different surface area, bulk density and contact mechanisms in grinding

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. Cylpebs produced faster breakage rates than ball charges under the same mass and surface area conditions. In addition, the

Breakage Characterization of Grinding Media Based on

The grinding media that is most often employed in grinding is steel balls. Since the 1950s, other types of grinding media, such as cylinders, cones, hexagons, cylpebs, and anisotropic media, have been used in the grinding process [].It is generally accepted that grinding is a random process in which the degree of grinding depends on the probability of the mineral entering into the region

grinding media charging procedure for mills

Comparison of grinding media—Cylpebs versus balls In the recent years other grinding media with different shapes have appeared in the market, such as Cylpebs developed by the Doering International, Powerpebs by the Donhad and Millpebs by the Wheelabrator Allevard Enterprise. For example, the Doering Minipebs were used in a ϕ × m tower mill with a charge of 183 tonnes operated

The effects of grinding media shape on breakage rate

ground by balls and Cylpebs are illustrated in Figs. 1 and 2,respectively. The results indicate that grinding of all size fractions can be described by first order grind- ing kinetics with 0.9197–0.9991 correlation coefficients. Variations in specific rates of breakage at different feed particle sizes for ball and Cylpebs grinding charges are shown in Fig. 3 . The specific rate of

Grinding Cylpebs 911Metallurgist

Cylpebs of equal diameter and length have 14.5% greater surface area than balls of the same mass, and 9% higher bulk density than steel balls, or 12% higher than cast balls. As a result, for a given charge volume, about 25% more grinding media surface area is available for size reduction when charged with Cylpebs, but the mill would also draw more power.
