Erect the Spiral Separator, calibrate the perpendicular line and fix it in a proper position with iron structure or wood. Send the mineral sand with the sand pump to the two feeding mouth on the top of the spiral chute, add make-up water to adjust the density of the ore pulp, and the ore pulp will naturally rotationally flow down and produce an inertial centrifugal force in the rotary slant flow. The gravity and the centrifugal force will separate the ores and sand according to the proportion, granularity and shape of the ore sand, and the ore concentrate will flow into the concentrate funnel and be discharged with the pipe and the tailings will flow to the tailing funnel and be discharged to the sand tank with the pipe and drained by the sand pump to complete the whole separation process.
