  • How to choose the size, filling Alumina grinding ball

    Alumina ceramic grinding balls have the characteristics of high strength, high hardness, high wear resistance, high specific gravity, small size, hightemperature resistance, corrosion resistance, ironfree, nonpolluting, etc, and are widely used in ceramics, glazes, glass, etc The grinding of nonmetals is the grinding medium of ball mills, pot mills, vibration mills, etc Its performanceIn Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill isCalculate and Select Ball Mill Ball Size for Optimum GrindingMethod of Steel grinding ball proportioning The method of ball distribution for a ball mill can be summarized as follows: 1 Take all the ore samples from a ball mill (usually take new ore and returned sand samples, then match the samples in proportion) for sieving analysis Divide them into several particle sizes, such as 1812, 1210, 108Method of Steel Grinding Ball Proportioning and Example

  • Optimum choice of the makeup ball sizes for maximum

    As the size reduction ratio increases, the optimum ball ratio moves towards more small balls At the finest grinding with a size reduction ratio of 128:1 (Fig 7d), a 508 mm/254 mm ball mix at a 13:87 ratio was found to be the optimum mix This indicates that the finer the product size, the higher the proportion of smaller balls that is requiredThere should be atleast 25% empty place in the milling jar after feeding balls and the material while high energy impact There is no such thumb rule for powder to ball ratioHow can one select ball size in ball milling and how muchAs for as ball to powder ratio is concerned, if the purpose is mixing you should go for 510 ration of ball with powder In case if you want to reduce the size or ally the powder then select highBest way to determine the balltopowder ratio in ball
