1.Introduction ball mill is an efficient tool for grinding many materials into fine powder.The ball mill is used to grind many kinds of row materials.There are two ways of grinding the dry process and the wet process.It can be divided into tubular type and flowing type according to.
Furthermore, in the ball race mill the motor current varies with load saving power when the mill is running at part load.Excellent wear characteristics the mill design facilitates that a major portion of the grinding occurs coal to coal rather than coal to metal increasing the wear life of the grinding elements.
However there is a trend towards ball mill grinding for product sizes below the traditional ball mill cut-off of 45 m.The effect of ball size on the feed and product size distributions in a fine grinding situation was studied.The grinding tests identified a number of trends for fine grinding.
A laboratory tower mill was used to investigate the effect of some variables on the power requirements of a plant mill.The grinding laws were tested for fine grinding and charles law and rittingers law was found to most closely satisfy the experimental data.The effects of ball size, ball charge mass and media type were investigated.
Option 1 - fag ball the original autogenous circuit proposed in previous reports.In this circuit, a primary gyratory crusher is used to control the ore top size.The ore is then fed into a large diameter, high aspect ratio fag mill.Pebbles are removed from the fag mill and used in the secondary pebble mill.

Fig.4 schematic representation of movement of grinding balls in a ball mill fig.3 bimetal composite liner castings a for 3.6 m ball mill and b for 5 m ball mill 1.3 heat treatment the composite liners were heat-treated at 1,223 k for 120 min to destabilize austenite and then air cooled to room temperature.
Depending on the mill size the sag mills draws between 2 mw and 17 mw.The product from the sag mill is further reduced in size using pebble crushers and ball mills.Hence, typical gold or copper ore requires between 2.0 and 7.5 kwh per ton of energy to reduce the particle size.Considering a typical mining operation processes 10,000 to 100,000.
