Effect of Grinding Media on Milling

Of Grinding Media On Sag Mill Performance increases metal on metal contact between the balls causing increased wear of the grinding media and reduced grinding efficiency. The ball mill optimier will use sump water cyclone underflow water cyclone pressure and pump speed to process the material from the SAG mill and control the final grind.

The effects of grinding media shapes on the grinding ...

01.02.2013· The effect of the media shape on grinding kinetics of cement clinker in a ball mill was investigated. Results indicated that cement clinkers obey first-order breakage kinetics in the case of both balls and cylinders. The specific rate of breakage provided by cylinders is higher than that of balls. The results also showed that −

Effects of grinding media shapes on load behaviour and mill ...

Grinding media directly affect the load behaviour and consequently the operations of industrial mills in terms of product size, energy consumption and grinding costs. Size and shape distribution of the originally spherical balls changes continuously as a result of impact breakage and due to different wear mechanisms taking place inside the ball mills. The wearing and breakage produce mostly ...

Ball mill - Wikipedia

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.

01.09.2013· Fig. 10 shows the effect of these two parameters on the optimum composition of the make-up balls when grinding a feed of 90% passing 9.5 mm at a size reduction ratio of 45:1 using a 1 m diameter mill. With an α value of 0.93, the optimum mix was found to be 30% of 50.8 mm balls and 70% of 25.4 mm balls.

Mill (grinding) - Wikipedia

Attrition between grinding balls and ore particles causes grinding of finer particles. SAG mills are characterized by their large diameter and short length as compared to ball mills. The inside of the mill is lined with lifting plates to lift the material inside the mill, where it then falls off the plates onto the rest of the ore charge. SAG mills are primarily used at gold, copper and ...
