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 ...
3. Mill head 4. Trunnion liner 5. Bearing liner The best a ball mill can get FLSmidth has installed almost 4000 ball mills at locations worldwide which has given us a unique insight into the stresses and strains arising out of ball mill operations. The large alternating stresses placed on ball mill trunnions and heads are a great example.
Steel balls are one of the most widely used grinding media in cement ball mills, their diameters can range from 20mm to 150mm according to different grinding requirements. In a cement ball mill, generally, φ50100mm steel balls are used in the coarse grinding chamber, φ2050mm steel balls are used in the fine grinding chamber. 2. Short Cylinders.
