## Mill Critical Speed Calculation

· The speed of the mill was kept at 63% of the critical speed The face angle was varied from 90 to 111 degrees for the three types of configuration 1, 2 and 4, as shown in the figure Also, the height of the lifter bar in configuration 3 was changed to observe the trajectory It was observed that the ball trajectories could be controlled by the face angle and the height of the lifter bars· Wikisagmilling has server used 372355034 (Switzerland) ping response time Hosted in Register Domain Names at Omnis Network, LLC This domain has been created 21 years, 186 days ago, remaining 9 years, 178 days You can check the 6 Websites and blacklist ip address on this server Website information; Top 10 Domain Providers; Performance Score(Mobile) PerformanceWikisagmilling | 9 years, 178 days left· https://www911metallurgist/blog/ballmill Learn about Ball Mill Critical Speed and its effect on inner charge movements The effect of Ball Mill RPM sBall Mill Critical Speed & Working Principle
