Steel ball , grinding body of ball , abrasive of ball ***** the ball mill grinding body&#**9;s gradation that the basic principle is: 1. material&#**9;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 . the ball milling the highest efficiency ratio is as follows , which is economic operation status: Steel balldiameter mm φ**0 φ*0 φ*0 φ*0 φ*0 quality/feeding capacity 7.5% 6.9% *3.5% *0.1% *2% 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 *0% of max ball feeding of ball mill . Ration of steel ball feeding is added as per size Φ**0Φ**0Φ*0Φ*0Φ*0 Addition of steel ball : Total ball feeding is different for different ball mills .For example, MQG***0×***0ball mill milling quantity *****0Ton Max addition of steel ball ***** of steel ball for once , bigger ballΦ**0 and Φ**0occupies *0%*0, middle balls *0 occupies *0%*0, small ballΦ*0Φ*0occupies*0. 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 ball*1.2 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 ***0, the added steel ball size isφ**0, φ*0, φ*0. Ball mill diameter is more than ***0, the added steel ball size is φ**0, φ**0, φ*0.
