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.
