Converting a ball mill from overflow to grate discharge
Therefore, the need to make full use of these machines and their installed power is critical, so that this energy is effectively utilised. Converting a ball mill from overflow to grate discharge involves installing a grate inside the mill at the discharge end. The grate holds the balls inside the mill but allows the slurry to pass through, and ...Web
