09-04-2015 Some mills are compartmentalized with each subsequent section having a smaller ball size. The material can pass through to the proceeding section, but the balls cannot. This ensures that the smaller particles are attacked by the smaller grinding media. Ball mill is a versatile grinding mill and has a wide range of applications.

11 Best Grain Mills In 2021 - MomJunction
14-12-2020 Burr mills: They are the most common and consist of two grinding plates, fixed and rotating. Burr mills can be stone burrs that crush the grain or the steel burrs that break the grain. Impact Mills: They consist of two different stainless-steel heads where the grain is dropped into the mill, which crushes the substance into a fine powder.

Best energy consumption - CemNet
16-02-2015 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 circulating loads of >1000 per cent.
