Pebble Mill Grinding 911metallurgist

Little or no increase in power or pebble consumption was noticed. Tests run by Sylvanite Gold Mines in Canada have shown 13% to 25% more -200 mesh produced on a power basis in a Grate Tube Mill than produced in an overflow tube mill. On the basis of mill volume the grate mill shows 10% to 29% more capacity per cubic foot than overflow tube mills.

Similar to slurry flow-back, the pebbles flowing back into the mill increase with larger pebble port or grate slot size. As the pebbles flow down and slide across the grate slots, they get an equal chance to go back into the mill. Similar to slurry pool formation, pebbles flow-back would increase the quantity of critical size material in the mill.
