What Is The Difference Between A Ball Mill And A Rod Mill?
The rod mill fine grinding fineness is about 0.833-0.147mm. In terms of the fineness of the ground material, the ball mill has a finer handling ability. In terms of operation, ball mills and rod mills are quite similar. Both use a rotating cylinder and liners to protect the cylinder from wear and tear.
9 Difference Between Ball Mill and Rod Mill | How To …
The discharging fineness of the material milled by ball mill is between 0.074-0.4mm, and that of the material milled by rod mill is between 0.833-0.147mm. 6. Running Cost. The power consumption of the ball mill is slightly higher than that of the rod mill, and the wear rate is also higher than that of the rod mill.

What Is The Difference Between A Ball Mill And A Sag Mill?
In a SAG mill, balls of up to 150mm in diameter occupy 5%-18% of the mill chamber volume. In contrast, a ball mill contains grinding media up to 50mm in diameter, occupying between 25% - 40% of the mill chamber volume. Another difference is the type of grinding media used. Ball mills typically use steel rods, steel balls, or similar media to ...
SAG mill VS Ball & Rod Mill
SAG mills are used predominantly with feed material with a larger max lump sizes (from primary crushing plant typically in the max lump size range 150 mm to 300mm and a psd to follow) and the ball or rod mills are for smaller feed lump sizes.
The Difference Between the Ball Mill and Rod Mill
The Difference Between the Ball Mill and Rod Mill. Rod mills are very similar to ball mills, except they use long rods for grinding media. The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1 ...
Grinding Mill Power
Thus the power to drive the whole mill. = 49.5 + 66.0 = 115.5 h.p. = 86 kW. From the published data, the measured power to the motor terminals is 103 kW, and so the power demand of 86 kW by the mill leads to a combined efficiency of motor and transmission of 83%, which is reasonable.
