Chrome Mining Process
Process: First use hopper and vibration screen feeding stone chrome to preliminary crusher, then to fine crusher, Then use a belt to a hopper, underside the hopper has a feeder, feeder 0-20mm size to ball mill, ball mill working together with a spiral classifier, then get 0-1mm size to shaking table, shaking table also has two-stage, one for preliminary, one for fine.
