Ball Mill

Ball Mill Ball Mills are horizontal rotating cylindrical steel chamber of half filled with steel balls. The size reduction is accomplished by the impact of balls as they fall back after being lifted by the baffles fitted in the rotating chamber. Ball Mill is fitted on a sturdy MS frame. Charging of balls and material is done by the means of opening provided in the chamber. The chamber is turning about the horizontal axis through a reduction gearbox drive through a ½ HP variable speed motor. Drive is provided to vary the RPM. A RPM indicator with proximity switch is provided in the set-up. A revolution counter is provided to find out the number of turns. Special arrangement is done to free the Ball Mill from reduction gearbox for charging and discharging the material. Experimentation: To study effect of RPM on the power consumption of a Ball Mill.
