Difference Between Sag Mill vs Ball Mill

The ball charge of a SAG mill is about 29% to 30% By friction and influence of tumbling balls inside rotating cylinder grinds the raw material to the required fineness The internal machinery of ball mill grinds the raw material into the powder-like material And if extreme fineness and refinery are required then rotation go on continue Get price


It's the time to note Ball Mill's essential Speed

When the rotating speed of ball mill exceeds a particular speed (with a lot of higher speed) the steel ball can rotate with the barrel and will not crumple during a condition of centrifugal movement there's no impact force that the grinding operate is way less and therefore the ball mill stop grinding Get price


Case Study

Before CP Ball mill/Blunger is a batch grinding process As per the process requirement the motor should run at full speed during the start of batch however after a particular time the ball mill or Blunger can be rotated at less speed (R PM) The load survey conducted on the ball mill shows that the average loading on ball mill motor is 58 1 % Get price
