The tailings dry drainage cyclone mainly adopts the working principle of centrifugal sedimentation. The dry tailings cyclone is often used in combination with the dewatering vibrating screen. After the tailings are concentrated by the cyclone, the underflow enters the high-frequency vibrating dewatering screen for dehydration, which can make the water content of the tailings within 15% and achieve the purpose of draining the tailings.

Dry tailings discharge is a process in which the tailings after concentrate extraction are concentrated and dehydrated to form materials with a water content of less than 15% and then transported to the dumpsite for storage or recycling. When the mixed liquid to be separated enters the cyclone from the inlet of the cyclone at a certain pressure, a strong three-dimensional elliptical strong rotating shear turbulence is generated. Due to the different densities of particles, the centrifugal force, centripetal buoyancy force, fluid drag force, etc., they are subjected to are different. Due to the effect of centrifugal sedimentation, most of the coarse particles are discharged through the bottom outlet of the cyclone, and most of the fine particles are discharged from the overflow pipe, so as to achieve the purpose of separation and classification.

The tailings dry drainage cyclone can be lined with polyurethane or rubber and can be lined with different characteristics of rubber according to the specific properties of the slurry. The life of the entire production line is twice that of the ordinary equipment production line, which greatly reduces manual maintenance and reduces operating costs. The dry tailings discharge process solves the problems of environmental pollution, hidden safety hazards and large amounts of land occupied by traditional tailings discharge tailings and the full tailings dry discharge process design.
