Ball mills tumble iron or steel balls with the ore. The balls are initially 510 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills dry basis is typically 75 vol.- ore and 25 steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.
Ball Mills. Ball mills have been the primary piece of machinery in traditional hard rock grinding circuits for 100 years. They are proven workhorses, with discharge mesh sizes from 40M to 200M. Use of a ball mill is the best choice when long term, stationary milling is justified by an operation.

After crushing process, if you want to get much smaller material you can send copper ore ball mill for further grinding. Within the ball mill, the crushed copper ore will be grinded to about 0.2 mm with 3-inch steel balls. This copper ore slurry is finally pumped for the flotation deck with the fine sulfide ore -0.5 mm going to froth ...

INTRODUCTION The Nevada Commission on Mineral Resources, endeavoring to facilitate development in the mineral industry in the State, initiated a study in early 2018 intended to answer the following two questions. 1 Is there a need for a custom
Our mills run the ore through ball and rod mills to reduce it to the proper size for our flotation process. Flotation separates the copper, zinc and lead. After separation, the various concentrates are dried to the consistency of a damp powder before being stored in our enclosed storage and shipping facility.
