Ball Mill Length Diameter Ratio

ball mill discharge grind size,i am working in a plant with single stage grinding using a ball mill we operate the mill power at around circulating load ratio? ball mill is in closed circuit with the cyclones. mill diameter inside liners is 4m, effective grinding length is 5.3m, .l / d ratio in overflow ball mill design & operation,the ratio was increased progressively from then on, reaching 1.6 and 1.8/1 there is a limit to ball mill diameters because of the demonstrable limit to axial c) reduced comminution of coarser feed sizes, probably due to .optimum choice of the make-up ball sizes for maximum ,fig. 11 shows the results of the grinding of a feed of various sizes at a size reduction ratio of 45:1 using a 1 m diameter mill. it can be seen that the optimum portion .durable with high ball mill ratio,the ball mill is a tumbling mill that uses steel balls as the grinding media. the length of the cylindrical shell is usually 11.5 times the shell diameter (figure 8.11)..
