Ore samples were taken from a grinding mill operating as a batch process. The feed size distribution, breakage functions and size analysis of samples taken at intervals of 10 minutes up to 30 minutes are given. Determine: 1. The breakage rate of the top two feed sizes 2. The % passing 710 μm after 1 hour of operation.

Sep 13, 2021 The main operating parameters of the sand mill Sand mill flows: It affects product fineness, output, and particle size distribution. Flow rate and output are two different concepts. In the continuous grinding process, the absolute value of the two is equal. In cyclic grinding, the output is 1/n of the flow rate (n cycles).
