    how itworks crushers,grinding millsand 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. Autogenous grinding mills use larger rocks to impact and break smaller rocks as the mill rotates

    Similar to the impeller design affecting pump capacity, the pulp lifter design affects the discharge capacity (or mill throughput) of AG and SAG grinding mills. Generally, the discharge from AG/SAG mills consists of one or both of the following components: slurry (water and finer particles) and pebbles (20-100 mm). Single stage AG/SAG mills have to handle large amounts of slurry as they are generally in …
