Apr 28 2017 Working Ball Charge in Ball Mill Suppose that once every week the mills are stopped and all balls less than 2 in. in diameter are removed. If the ball wear is 2 lb. per ton of ore crushed this will amount to 720 lb. (326.5 kg.) per day for each mill.
Chat OnlineAbstract The law of ball size distribution in the horizontal planetary ball mill is studied by the discrete element method. The results show that the maximum impact energy could be acquired when filling rate is 24 moreover the biggest mean contact force and the highest energy utilization ratio of balls could be acquired when the speed ratio is 1.5.
Chat OnlineThe properties and preparation of talc have long been investigated due to its diverse industrial applications which have expanded recently. However its comminution behavior is not yet fully understood. Therefore having better control of the particle size and properties of talc during manufacturing is required. In this study we investigate the effect of the ball size in a high-energy ball

Chat Online· To have a pulp as dilute as 20 percent solids the ball load was drawn down to 30 percent volume and the ore charge proportionately reduced. Water was then added to fill the mill. The results of grinding were much like those with 33 percent solids. All in all 33 percent solids was the best for efficiency and selective grinding.
Chat Online· Effect of Balls Hardness on Rate of Grinding Tests by Coghill and Devaney show that the hardness of the balls has some effect upon the rate of grinding in mill. These results are plotted in Fig. 6.8a and it is seen that both for dolomite and chert there is an increase in the rate of grinding with increasing hardness of ball.
