  • What should be the ideal proportion of ore to grinding

    achieving coarse grinding in a ball mill is the function of a number of parameters 1, The mill L/D ratio must be low, for example diam. 9ft x 10ft long. 2, The mill must be of grate discharge configuration as opposed to overflow discharge. This will ensure a steep hydraulic gradient in the mill for rapid passage of the ore through the mill.
