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

Get DetailNov 01, 2006· Impulse tests are often used in real mills to measure the residence time distribution of certain types of particles and particularly for tracer materials. With these types of long term DEM simulations we can also perform impulse tests to examine the way that a group of test particles migrate through the mill when added together at one location near the feed end of the mill
