Square Swing Sieve
The square swing screen is a kind of high-efficiency screening machine specially designed to meet the needs of large-capacity and high-precision screening.The square swing sieve has a large sieve weight and a multi-layer grading design. One machine is divided into two groups, and one is used for more than one unit. Flexible screening, the acceleration is 4-5 times lower than the ordinary vibrating screen, and the service life is increased, thereby reducing the maintenance cost. The large-scale electrostatic spraying process makes the equipment more beautiful, wear-resistant, and rust-proof. Widely used in chemical industry, metallurgy, non-ferrous metals, non-ferrous metals, food, abrasives and other industries.
Principle of square swing screen:
From the perspective of the trajectory of the shaker of the screen machine, that is, the square rotary screen is also called a reciprocating screen. The vibration force generated by the driving device is an inertial force that changes around a fixed axis and direction in a certain law. Its essence is caused by the eccentric wheel. The reciprocating inertial force formed by rotation around a fixed axis. According to the structural characteristics and working principle of the swing screen, the screen surface is generally horizontal or slightly inclined (inclination angle is 0°~5°). The working principle of the rotary screen is that after the screen machine is started, the shaker of the screen machine, that is, the screen box reciprocates back and forth under the action of inertia, and the screen box drives the screen surface to periodically shake, so that the material on the screen surface follows the screen box Plane whirl movement together, during which, materials smaller than the aperture of the sieve surface fall to the lower layer through the sieve hole and become under sieve. Materials larger than the aperture of the sieve surface are discharged from the discharge port after continuous tumbling and jumping movement to complete the screening work.
