Feb 16, 2015 Grinding energy was approximately 50 per cent of the ball mill and the drying capabilities allowed direct processing of materials of up to 20 per cent moisture content. The main energy issue was the high power consumption of mill fans, with pressure drops of 100mbar not uncommon with high nozzle ring velocities ( 70m/s) and internal mill

For example, ball mills use large media, normally or larger, and run at a low 10-50 rpm. Other mills, such as sand, bead, and horizontal, use smaller media from 1/64 to 1/8 , but run at a very high 800-1200 rpm. High-speed dispersers without media run even faster, 1200-1800 rpm, with tip speeds of 5000-6000 ft/min

Sep 21, 2019 Tumbling mills (Rod mill) In a rod mill, much of the reduction is done by rolling compression and by attrition as the rods slide downward and roll over one another. The grinding rods are usually steel, 25 to 125 mm (1 to 5 in.) in diameter, with several sizes present at all times in any given mill. The rods extend the full length of the mill
