What Factors Will Affect The Screening Efficiency Of Circular Vibrating Screen In Mineral Processing?

TSX concentrator vibrating screen is mainly used for classification, including horizontal vibrating screen, banana vibrating screen, circular motion vibrating screen and grizzly feeder. It is particularly important to select reasonable screening equipment according to different production processes or production lines. The TSX circular motion vibrating screen of mineral processing equipment is composed of vibrating system, screen body, screen plate, damping spring and other components. The following factors affect the efficiency of vibrating screening equipment.

(1) Screen plate area. It mainly refers to the effective sectional area of sieve plate, i.e., the volume of sieve openings. The larger the sieve plate area and effective sectional area of sieve plate, the higher the output of vibrating screen. Therefore, to increase the output of The TSX circular motion vibrating screen, the length and width of the screen plate can be appropriately increased, the quality of the wire can be improved, and the effective sectional area can be increased.

(2) Vibration frequency and amplitude. The sieving materials are leaping forward on the screen surface. The higher the vibration frequency is, the faster the material movement speed is, and the higher the output of The TSX circular motion vibrating screen is. When the frequency of The TSX circular motion vibrating screen is constant, the magnitude of the exciting force is determined by the amplitude.

Increasing the amplitude will make the material jump farther and speed up its movement. However, if the amplitude is too large, the contact opportunity between materials and sieve plate will be reduced, and the output of vibrating screen will be reduced; If the amplitude is too small, the movement speed of material particles on the screen surface will slow down, even some particles cannot vibrate, which will also affect the output and screening purity of The TSX circular motion vibrating screen.

(3) Inclination of sieve plate. If the inclination is too large, the particle movement speed on the sieve plate will be accelerated, and the number of contacts between the material particles and the sieve plate will be reduced, which will reduce the chance of particles being screened down and the output of The TSX circular motion vibrating screen.

If the inclination is too small, although the material has enough time to stay on the sieve plate, the output and screening purity of The TSX circular motion vibrating screen will also be affected due to the slow movement rate of material particles on the screen surface and excessive material on the screen area. Therefore, during screening operation, the inclination of The TSX circular motion vibrating screen should generally be 15 °~25 °.

(4) Feeding condition. The TSX circular motion vibrating screen shall be fed evenly. If the material is too thick, the screening purity will be affected. If the material is too small, the output will be low. Therefore, frequent inspection and adjustment must be carried out according to the incoming materials and equipment operation to ensure the purity and improve the output. In addition, the moisture content of the material will also affect the screening output.
