Ball Mill and Grinding Circuit Preparation for Start-UP The following items must be checked before the equipment in the Grinding Circuit is started. Check the ore slot feeder for obstruction or hang—ups. Check the ball mill belt feeder for undue buildup of material. Check oil level in ball mill lube oil tanks. Also, check grease level in the mill ring gear spray lube drum.
A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement.Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
A ball mill is a type of grinder used to grind and blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.
