Principle Overview
The finely ground slurry is fed into the water tank from the feed inlet located in the middle of the settling zone. Below the inclined water tank is the slurry grading settling zone, where the spiral rotates at low speed to stir the slurry, causing fine particles to suspend and overflow at the overflow weir. Coarse particles settle to the bottom of the tank and are transported by a screw to the discharge port as return sand for discharge. The position of the overflow weir is higher than the bearing center at the lower end of the spiral shaft and lower than the upper edge of the overflow end spiral.
Equipment Features
An automatic sand return lifting device has been added to the sand return end, and the ball mill has removed the configuration of a large spoon head;
Each ton of ore can generally save 1-1.5 degrees of electricity;
Avoiding frequent maintenance of the big spoon head of the ball mill;
Reduced the uneven impact of the ball mill on the large and small gears.
Scope of Use
Suitable for coarse particle grading.
