Wet Overflow Ball Mill | High Efficiency Ore Grinding Equipment For Small & Medium Mining Projects
Ball mill is the core fine grinding equipment in mineral processing lines. The wet overflow ball mill is the most popular model for gold, tin, tungsten and chrome ore beneficiation. It crushes raw ore into fine particles, which will be delivered to shaking tables for gravity separation to improve metal recovery rate. Our series ball mills cover small lab test models, medium mine models and large heavy-duty models, perfectly matching different budget and output demands of small & medium mine investors.
Working Principle of Wet Ball Mill
The motor drives the cylinder to rotate continuously. Steel balls inside the barrel produce strong impact and grinding force under centrifugal and friction effect. Raw ore and water are fed together for wet grinding. Fine mineral slurry flows out from the overflow port, and coarse ore stays inside for secondary grinding. The uniform fine slurry can directly enter shaking table, trommel screen or other sorting equipment.
