cushioning effect in ball mill

AMIT 135: Lesson 7 Ball Mills & Circuits Mining Mill

Overloading tends to accumulate fines at the toe of the mill which results in a cushioning effect. When the rock load is low, excessive ball-to-ball contact retards the rate of breakage. The fraction of mill volume occupied by the ore, J↓R :

The speed at which the ball mill jar rotates is responsible for maintaining the slope of the cascading media pile, which is known in combination of the reduced cascading zone in addition to the cushioning effect. For most materials you will be grinding, a 25% material charge (relative to jar volume) is the ideal load. There are

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

Tubular Ball Mills ScienceDirect

Jan 01, 2016· A survey of 40 industrial mills in Australia found that the maximum ball mill diameter in use was 5.34 metres and length 8.84 metres . Autogenous mills range up to 12 metres in diameter. The length-to-diameter ratios indicated in Table 7.1 for ball mills are for normal use, but for primary grinding the ratio could vary between 1:1 and 1.8:1

Effect of Water & Density on Grinding Mill

The Time that the ore spends in the grinding mill is called, RETENTION TIME. This is a very important variable, the longer the retention time, the more the ore comes in contact with the rods, the better and finer the grind becomes. To understand this important control it must be remembered that any volume that is added to a circuit must leave the circuit at exactly the same rate. All the
