How the vibrating chute works

The pulp is fed tangentially from the front end of the agitating chute concentrator, and moves down in the fixed agitating chute by gravity. The low-density mineral particles are located in the upper layer, while the high-density mineral particles are located in the bottom layer. The ore particles in the upper layer are greatly affected by the high-speed water flow, and the frictional resistance is small, so the movement speed is high and the centrifugal force is large. The influence of the water flow is small, but the frictional resistance is large, so the movement speed is small and the centrifugal force is small, and during the movement, due to the inclination of the bottom of the chute section, these ore particles slowly move down along the spiral groove of the spiral concentrator, and the lateral direction of the water flow Circulation strengthens the sorting process and is another important condition for sorting. How does the lateral circulation of water flow occur? On the one hand, the water flow in the spiral concentrator moves downward, on the other hand, the upper water flow moves outward, and the lower water flow moves inward. The speed of the upper water flow is higher than that of the lower water flow, so the upper water flow has a larger inertial centrifugal force and a faster speed. , is thrown to the upper part of the agitating chute, the rotation speed of the water flow is slow, the centrifugal force is small, and it flows from the upper side to the lower side under the action of gravity. The influence on the ore particles in the cross section, and the interaction of various forces of the ore particles, the ore particles move along the spiral groove at different speeds, therefore, the ore particles have different densities, and the particle size and shape are separated in different directions: high-density ore particles Located on the inner side, the concentrate can be intercepted from the upper part of the spiral concentrator, the medium ore can be intercepted from the lower part, and the ore particles with less density are located on the outer side, which become tailings and are discharged from the tail.
