steel ball and cylpebs

Steel ball and cylpebs , grinding body of ball mill .

How to caculate  ball mill steel ball gradation method to be very many kind, the basic principle is: 1. material's degree of hardness is big, chooses the steel ball diameter to be big; the 2. grinding machine diameter is big, the impulse is big, chooses the steel ball diameter to be small; 3. uses the double hopper  partition board, the diameter should be smaller than the same dump cross section single-layer clapboard; 4. the general fouth gradation ball, bigger ball, the pellet are fewer, the middle ball is more , namely two ends fewer, middle more ......

How to add the ball into ball mill as per size and proportion of steel ball .

New installed ball have a process of running-in ,during the process of running-in ,The first added ball quantity is 80% of max ball feeding of ball mill . Ration of steel ball feeding is added as per size Φ120Φ100Φ80Φ60Φ40
Addition of steel ball :  Total ball feeding is different for different ball mills .For example, MQG1500×3000ball mill milling quantity 100150Ton Max addition of steel ball 9.510Ton..Addition of steel ball for once ,bigger ballΦ120 and Φ100occupies 30%40,middle balls 80 occupies 40%30,small ballΦ60Φ40occupies30.

Weight of addition of steel ball is according to quality of steel ball .Best steel ball  0.8 to be added for milling one ton ore .Normal steel ball11.2 to be added for milling one ton ore .

Ratio of size of steel ball : Different model ball mills that the ration of steel ball is different .

Ball mill diameter is less than 2500,the added steel ball size isφ100, φ80, φ60.

Ball mill diameter is more than 2500, the added steel ball size is  φ120, φ100, φ80.
