2019-11-26  The feed size is usually between 20-30mm and the product size is 0-3mm. Feed. Both the autogenous grinding mill and the ball mill feed parts are welded with groove and embedded inner wear-resistant lining plate. As the sag mill does not contain grinding medium, the abrasion and impact on the equipment are relatively small.
