10/26/2018· Faster RPM are required for smaller mills to reach critical speed. To minimize any grinding or dispersion issues, we aim for the cascading action discussed prior. The most desirable angle to accomplish this falls between 50 to 60° from horizontal. The lower end of this range applies to wet grinding applications for soft materials.
