Vertical Mills Suppliers @ ProcessRegister.com
Vertical Mills use a double helix screw to stir the grinding media, which can be steel balls, ceramic media or pebbles. Feed enters the top of the mill and an external recycle pump provides an upward rise velocity in the grinding chamber. Grinding is by attrition and abrasion. Less energy is required when compared to conventional tumbling mills.

How it Works: Crushers, Grinding Mills and Pulverizers
Pebble mills use rock pebbles as the grinding media to cause friction and attrition between the pebbles and ore material. Pebble mills may be used when metal balls must be avoided. Autogenous grinding (AG) and semi-autogenous grinding (SAG) mills use the material to be ground as the grinding media.

Rod mills, how they function
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 1.4 to 1.6.
