High Weir Screw Classifier
Principle Overview
The finely ground slurry is fed into the flume from the inlet located in the middle of the settling area, and the inclined installation of the flume is below the slurry grading settling area.
Below the flume is the slurry grading and settling area. The spiral rotates at a low speed, stirring the slurry and suspending the fine particles to the top.
The spiral rotates at a low speed, stirring the slurry and suspending the fine particles to the top, where they flow to the overflow weir and overflow. Coarse particles sink to the bottom of the tank and are transported by the
The coarse particles sink to the bottom of the tank and are transported by the spiral to the discharge port as returned sand. The position of overflow weir is higher than the bearing center of the lower end of the screw shaft and lower than the overflow end.
The position of the overflow weir is higher than the bearing center of the lower end of the screw shaft and lower than the upper edge of the screw at the overflow end.
Features of the equipment
◎ An automatic lifting device for sand return is added at the sand return end, and the configuration of large scoop head is canceled in the ball mill;
◎ Generally speaking, it can save 1-1.5 degrees of electricity per ton of ore;
◎ Avoid frequent maintenance of the big spoon head of the ball mill;
Reduces the uneven impact of the ball mill on the large and small gears.
Scope of use
Suitable for coarse grains classification.
