Ball Mill Media Consumption

Consumption of steel grinding media in mills – A

2013-8-1  Moreover, the assumption of additivity of the different mechanisms may not hold, as abrasion and corrosion may work together to enhance grinding media consumption. Radziszewski (1997) has proposed a mathematical model describing ball mill wear as a function of mill operating variables. The wear model incorporated the energy dissipated in crushing, tumbling and grinding zones of the charge profile with adhesive and abrasive wear

The effect of processing parameters on energy

2015-2-10  Ball mills are vertical or horizontal cylinders (statio-nary tank), equipped with a rotating shaft with arms, filled to as much as 70% of the available volume with grinding media (usually steel balls). The mass and the balls are agitated by a shaft with arms, rotating at a variable speed. Generally, size reduction in any practical machine is achieved by mechanical forces (compression, impact or shear) that cause rupture while one of the forces is usually predominant. In the ball mill refiner the feed material is comminuted between the grinding media, the stirrer and the cylin-der wall by compression and shear [7,8]. The factors affecting the grinding action of the ball mill are the mill speed and quantity, type and size of grinding media. The aim of this study was to examine the effect of agitator shaft speed and amount of grinding media (steel balls) on energy consumption

Ball Mills - an overview ScienceDirect Topics

8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
