In a wide variety of industries, e.g. in the cement and steel industry, an explosive dust atmosphere is created during the grinding of coal and similar products. This can lead to explosions and therefore requires the consideration of constructional explosion protection measures in the form of pressure relief devices.
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 hydrocyclone's feed solids content (Sf)) with respect to …
