Minerals | Free Full-Text | Industrial Vertical Stirred Mills Screw
Vertical stirred mills are grinding equipment applied for comminution, especially for fine grinding in regrinding applications where feed material is under 1mm. The main parts of the equipment are the grinding chamber, internal liner, screw impeller, screw liner, motor engine, ball feeder, slurry feeder, and the discharge, as shown in Figure 1.
What Are the Differences between Dry and Wet Type Ball Mill?
The water can wash away the fine particles in time to avoid over-grinding. The wet ball mill has a low noise, and low environmental pollution. The wet ball mill has a simple transportation device with less auxiliary equipment, so the investment is about 5%-10% lower than that of a dry ball mill. The grinding particle size is fine and uniform.
