Optimization of mill performance by using online ball and pulp measurements Soon after a stop a mill is a dangerous place to enter for the personnel tasked with taking measurements or samples Crash stops are difficult to handle The mill and all feed streams should be stopped simultaneously but often they are stopped around about the same time

Analysis of ball and pulp flow in ball mills indicates that three factors may become critical with increasing mill diameters ball size fraction critical speed and average pulp flow velocities Ball diameters may need to be decreased and fraction critical speeds increased with ores which show decreased breakage rate coefficients above 1 2 mm (14 mesh) With 5 5-m (18-ft) and larger mills at

The motion of ball media in the tumbling ball mill is analyzed The impact parameters of the ball media caused by the falling motion are deduced The impact and attrition grindabilities are studied The grinding performance is expressed as the proportion of grindability of all collisions to that of the collisions of ball media in the arc of the

Ball Mill grinders are designed to reduce materials down to a fine powder using the impact and friction created by a large quantity of balls – generally made from steel but also available in other materials for specific applications – which are placed inside a rotating mill to create a cascading effect
