(1) Feeding and Crushing:

The system consists of a chute feeder, jaw crusher, hammer crusher, and belt conveyor. Raw ore with a maximum particle size of 150mm is fed into the hopper by an excavator or loader, then fed evenly into the jaw crusher via the chute feeder, where it is crushed to 0- 50 mm. It is then conveyed by the belt conveyor to the hammer crusher for further crushing to 0- 10 mm, and finally sent to the transfer hopper.

Note: The customer requires control over the raw ore feed particle size, which should be less than 150mm. The crushing system has a capacity of 2 tons/hour and operates for 10 hours per day. Customization is available upon request.

(2) Grinding and Classification:

A closed-loop grinding circuit consisting of a ball mill and a spiral classifier is used. Fine ore (0- 10 mm) is evenly fed into the ball mill for grinding via an electromagnetic feeder and belt conveyor. The discharged ore enters the spiral classifier for classification. The classifier return sand (coarse particles) is returned to the ball mill for regrinding, while the overflow (-200 mesh fine particles) is pumped to the mixing tank to ensure the flotation feed particle size meets the standards.

(3) Mixing and Preparing the Pulp

– 200 mesh slurry is introduced into the mixing tank, flotation reagents (collectors, frothers, modifiers, etc.) are added, and the mixture is thoroughly mixed to prepare for flotation operations.
