Wet ball mill load detection is mainly for the internal parameters of the mill that can accurately characterize ML (Material to ball volume ratio, MBVR, Pulp dnsity, PD, Charge volume ratio, CVR). In [3] a soft sensor model for ML parameters is established by extracting and selecting various spectral characteristics of the cylinder vibration signal. But it has poor generalization and low ...

We can calculate the steel charge volume of a ball or rod mill and express it as the % of the volume within the liners that is filled with grinding media. While the mill is stopped, the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill. The % loading or change volume can then be read off the graph below or ...

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the ...
