Ballrod mill literature the ballrod mills are meant for producing fine particle size reduction through attrition and pressive forces at the grain size level they are the most effective laboratory mills for batchwise rapid grinding of mediumhard to very hard samples down to finest particle sizes
For ball mill the grinding force of steel ball to ore is less than the impact because the contact area is small between balls and mineral thus the throwing motion of ball can produce a large impact but it need a high rotate speed and has a higher power consumption but for rod mill grinding effect is better which need a lower rotate speed

For ball milling there is an optimum speed where the centrifugal force at the top of the mill is just balanced by the force of gravity this caused the balls to be lifted to the maximum height before they fall onto the balls below thus imparting the most kinetic energy
Describe the ponents of ball mill explain their understanding of ball mill operation explain the role of critical speed and power draw in design and process control recognize important considerations in ball mill selection reading lecture in ball mills steel balls or hard pebbles to break particle based on impact and attrition
A ball mill critical speed actually ball rod ag or sag is the speed at which the centrifugal forces the critical speed of a rotating mill is the rpm at which a grinding medium will begin to check price ball mill critical speed for sale
The filling rate of the ball mill is 4050 the rod mill is 3545 the filling ratio of the selfgrinding machine is 2540 and the filling rate of the gravel mill is about 43 from the point of view of maximum production capacity per unit energy consumption the rotation rate of ball mill is 65 78
Rod mills are less mon than ball mills for grinding minerals the rods used in the mill usually a highcarbon steel can vary in both the length and the diameter however the smaller the rods the larger is the total surface area and hence the greater the grinding efficiency 5
A ball mill critical speed actually ball rod ag or sag is the speed at which the centrifugal forces equal gravitational forces at the mill shells get price so super orion ball mill ball mills are usually operated at 75 of the critical speed the critical speed is the speed where mathematically calculated the
