balls must not have too high velocities when they hit their surface, because they can be damaged or even broken. Therefore it is necessary to describe the movement and the surface structure of the balls under the in uence of the suspension. We model the dynamics inside the ball mill in dependence of the lling volumes of suspension and balls

SAG is an acronym for Semi-Autogenous Grinding. SAG mills are autogenous mills but use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. The largest SAG mill is 42' (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor.

"stirred ball mill." There are quite a few types of Attritors; we can categorize them as dry grind Attritors, wet grind Attritors, regular speed Attritors, and high speed Attritors. A useful and simple equation describing the grinding momentum is M x V (mass x velocity), which enables us to see how the Attritor fits into the family of mills.
throughput capacity of the mill, a number of wear measurements are necessary during the life cycle of mill liners. The liner wear reading can be used to calculate available volume inside the mill as the inside mill volume for ore grinding is a function of volume of mill liners. The measurement of .

1.3.2 Critical speed The faster the mill is rotated, the further the balls are carried up inside the mill and the greater the power consumption and the capacity of the mill. If the speed is too high, the balls are carried over and the mill is said to be centrifuging. Critical speed nc is the rotary speed beyond which the balls are centrifuging.

Rod mills are very similar to ball mills, except they use long rods for grinding media. The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6.
Addition of Grinding Balls Watch raw mill SEC daily and add grinding balls in right timing →10% energy saving expected Ball diameter shrinks as time passes due to erosive effect. This leads to gradual increase of raw mill SEC. Filling level of grinding balls is also important in grinding efficiency. Optimum level of filling should be maintained.

is a grinding mill containing internally agitated media. It has been generically referred to as a "stirred ball mill." There are quite a few types of Attritors; we can categorize them as dry grind Attritors, wet grind Attritors, regular speed Attritors, and high speed Attritors.
The mill is best used to crack whole grains with a minimum of "fines". It is not used as a final process for reducing the size of ingredients used in fish feeds. 2.5 Screening. Associated with grinding feeds for fish fry, a sieving system is required which classifies materials to any desired particle size.
