In the ball mill grinding process, the raw ore is ground to, accounting for 60%, and the magnetic separator is used for magnetic rough separation. The magnetic field strength is 96kA/m. The obtained coarse concentrate is reground to, accounting for %, the iron ore produced by magnetic selection with a magnetic field strength of 64kA/m.
Ball mills have shells of cast iron or steel plates and are carried on hollow trunnions. Ore is fed through a scoop, drumtype, or combination feeder at one end and is discharged from the opposite trunnion. Ball mills may be arbitrarily classified into two types, according to the method of pulp discharge. In highlevel or overflow mills the pulp level builds up until it overflows and
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 particlesize measurement device and sizecontrol cyclones.
