INVESTIGATION OF FEED DYNAMICS IN CLINKER GRINDING

Keywords: Clinker, dynamics, Feed, mill, residence, time. 1.0 INTRODUCTION The main raw material for cement production is clinker. Cement clinker is usually grounded using a ball mill. This is essentially a large rotating drum containing grinding media; normally steel balls. As the drum rotates, the balls cascade and crush the clinker.

Investigation of flow dynamics of porous clinkers in a

Dec 01, 2019· A radiotracer investigation was carried out in a ball mill of a cement plant in Kenya. Residence time distribution (RTD) of raw feed to the mill was measured using Technetium-99m adsorbed on the clinkers as a radiotracer. From the measured RTDs, solid holdup and mean residence times (MRTs) in the ball mill and associated separator were determined.
