Effects of grinding media shapes on load

01-11-2006  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.

Factors Affecting Ball Mill Grinding Efficiency

The following are factors that have been investigated and applied in conventional ball milling in order to maximize grinding efficiency: a) Mill Geometry and Speed – Bond (1954) observed grinding efficiency to be a function of ball mill diameter, and established empirical relationships for recommended media size and mill speed that take this factor into account. As well, mills with different ...

EFFECTS OF MIXTURE OF GRINDING MEDIA OF DIFFERENT SHAPES

It was found that mixtures of grinding media shapes can increase the breakage rate in a particular milling environment. But, spherical balls remain the most efficient grinding media. Finally, an optimal mixture made of grinding media of different shapes cheaper to manufacture can be used in the grinding process alternatively to 100 % balls.

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.
