Ball Mill By Mass International

BALL MILL
 


 
Ball Mills arc horizontal rotating cylindrical steel chamber of half filled with steel balls. The size reduction b 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 and a motor. An arrangement is done for moving the Ball Mill at different speeds. 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.
 

 
Range of EXPERIMENTS
 
       To study effect of rpm on the power consumption of a Ball Mill
 
       To determine the efficiency of a Ball Mill for grinding a material of known Wi
 
       To find the critical speed practically and theoretically and to study the effect of speed on efficiency
