Milling fineness in addition to the above every link outside, still and add steel ball size scale relevant. How to do it the steel ball size scale according to add steel ball mill the diameter size, the mineral hardness, into a ball ore size distribution, hardness steel ball (quality), ball mill rotary speed to determine the factor. Cone crusher

When the ball mill model, after the confirmation of the speed of the ball mill is determined. The mineral hardness is measurable. The particle size, ore into ball mill by changing the case to determine the size screen. How to steel ball size scale according to add to the ball mill steel ball? Now the author put the perennial theory and practice experience rules are as follows: the total

Usually, a new installation ball mill has a run-in period, in the process of integration of steel ball, for the first time to add, accounting for most of the ball mill with amount to 80%, the proportion of steel ball add may according to the steel ball size (Φ 120 ㎜, Φ 100 ㎜, Φ 80 ㎜, Φ 60 ㎜, Φ 40 ㎜) size added.

Adding amount of steel ball mill the assembly model: a different ball is different. For example MQG1500 x 3000 ball mill capacity (100 150 tons) largest amount with ball 9.5-10 tons. The first add steel ball ball (? 120? 100 ㎜) ㎜ and 30%, 40%, and 40% in 80 ㎜ ball--30%, ball (?? 40 ㎜) 60 and 30%. Why in ball mill run-in period of steel ball only add 80% of, because the ball mill after installation, ball mill tooth need mesh size, productivity (ore) is also gradually increasing amount to, to the ball mill continuous operation normal in two or three days, stopped to pick up the ball mill, the gearing mesh size check for everything is normal, open the ball mill manhole covers the second add the remaining 20% steel ball.

The ball mill boot operation to normal after, each class steel ball to add 3:4:3 (? 120 ㎜ according to 3, 100 for four, ㎜?? 80 ㎜ for 3) added. Note: small steel ball of the ball just for the first and add with. Because, during normal operation, steel ball mill and ball, steel ball and ore, steel ball mill and lining board from the friction between the reasonable, can make the abrasion resistance increases, make big ball grinding mill in small (ball), for the ball mill for the ball. So usually the normal condition, do not need to add ball. Add the ball is in the useful mineral grain size no monomer solution, when grinding machine from fineness can not reach the requirement, the flotation can add appropriate ball.

The ball mill of steel ball during the work, in order to keep the ball continuously wear rate and the ball by filling reasonable proportion of stable operation, keep the ball mill, must be reasonable for the ball, DiChang wear.

The weight of the steel ball added, according to the quality of the steel ball is, quality of steel ball, decide the ore tons of adding amount of consumption. Had better use new wearing steel ball. The best (good quality) add is to press processing steel ball every tons ore amount to calculate (that is, every tons ore add 0.8 ㎏) general steel ball handling a ton of ore (1 to 1.2 ㎏ ㎏-

Steel ball size scale: different ball mill type the different proportion. In 2500 the diameter of ball mill ㎜, add steel ball size is? 100 ㎜,? 80 ㎜,? 60 ㎜. Ball mill in 2500 ㎜ above, diameter add steel ball size is? 120 ㎜,? 100 ㎜,? 80 ㎜.

In addition, different equipment, different minerals to the operation of the equipment the differences. Jaw crusher
