Cement ball mills can be divided according to discharge method grate ball mills and overflow mills, and can be divided into wet mills and dry mills according to their processing conditions. Cement mill structure Ball mill is mainly composed of feeding part, supporting frame, rotary part, discharge, transmission, lubricant and cooling part.
An industrial ball mill operating in closed-circuit with hydrocyclones was studied by five sampling surveys. The aim of the present study was to optimise operating parameters i.e. charge volume, make-up ball size regime, slurry mean residence time, number of hydrocyclones in operation and hydrocyclones feed solids content S f with respect to increasing throughout from 225 to 300 tons ...
Ball mill. The ball mill is the fine grinding machine connect the SAG or AG mill and flotation machine. Ball mills produce fine particles with a uniform size for flotation, its grinding medias commonly are steel ball. The ball mill rolls grinding media together with the ore, as the ore grinds, these balls initially 5-10 cm in diameter but ...
The only manipulated variable available in the closed milling circuit ball mill 2 is the cyclone dilution water flow rate. Attempts to use this for density control were not successful. Because of the high magnetite concentration of the ore it was found that the actual density exceeded the required density,
