Flow Of Materials In Rod Mills As Compared To Ball Mills

Flow Of Materials In Rod Mills As Compared To Ball Mills

Jan 25 2012 As mentioned above the difference in the material flow behavior between the ball mill and the rod mill partially explains the well known difference in the product particle size distribution of ball mills and rod mills. In the case of ball mills the axial dispersion is higher and the mean residence time is shorter than those in rod mills.

Flow Of Materials In Rod Mills As Compared To Ball Mills

The rod mill product is characterized by its narrow size distribution if it is compared with that of a ball mill operating under the same conditions in open circuit. This is partly due to the bridging action of the rods over the coarse particles avoiding the fine sizes the grinding kinetics aspect and partly due to the nature of material .

Ball Mills

A ball mill is a type of grinder used to grind and blend bulk material into QDs nanosize using different sized balls. The working principle is simple; impact and attrition size reduction take place as the ball drops from near the top of a rotating hollow cylindrical shell.

Axial Transport In Dry Ball Mills

Axial Transport In Dry Ball Mills

Nov 01 2006 Charge material is dragged upwards by the motion of the liner and then avalanches down the free surface or thrown through the air as a cataracting stream. The material in the cataracting stream is ballistic and its motion will be predominantly in the radial–circumferential plane of the mill orthogonal to the mill axis.
