What Is The Difference Between Dry Ball Mill And Wet Ball Mill?
Wet ball mills have superior performance, higher grinding efficiency, and lower requirements for ore moisture content. In addition, it has fewer auxiliary equipment and simple material transport devices, so the investment is about 5%-10% lower than that of dry ball mills. From the perspective of economic effects of grinding operations, most ...
