On a 11 6 x 22 0 Ball Mill the trunnion bearing lubrication system provides continuous low pressure flood oil for cooling and lubrication of the bearings and high pressure oil for hydrostatic lift of the feed and discharge trunnions during start up of the mill System monitors including pressure switches and flow monitors are provided along with temperature sensors that monitor

Bearings in the steel mill and primary metal industry operate in extreme conditions These bearings must endure extreme temperature spikes coupled with rapid acceleration and deceleration These vastly demanding operational conditions are unique for metal industry thus putting steel mill bearings on the forefront of technology and engineering

Ball mills tumble iron or steel balls with the ore The balls are initially 5 10 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
