The swinging screen is a high-efficiency screening machine with large output and high-precision screening. The model of the shaking product: the pendulum sieve simulates the effective principle of artificial screening movement, and the material exhibits an involute spiral motion on the sieve surface, which is suitable for processing fine and super Fine range of powder and particulate 2 Hua β600 material. It has a production area of up to 5 times per unit area, accurate to six-stage separation, and the screening rate is as high as 90-95%. The system uses high-efficiency cleaning equipment such as silicone rubber balls and ultrasonic waves, and the screen holes are not blocked; closed dust removal, operation The acceleration is 4.5 times lower than that of the vibrating screen, and the life of the screened parts is increased while the maintenance is reduced; the noise is <75 dB. Optimized weight balance, low dynamic load on the foundation. Adapted to industries such as chemicals, food and spices, plastics, mining, medicine, wood and plywood, metallurgy, rubber, feed, fertilizer, sugar, salt, etc.
