Swing screen is designed to meet high production capacity, high-precision screening manufacturers and special design an efficient screening machines, screening is the most simple screening your eyes with both hands. Swing screening machine is a mechanical analogue of this, and it is the most efficient and effective to simulate the movement of the principle of artificial screening (screening accuracy, efficiency, and screen life are 5-10 times that of conventional circular sieve), meets all fine and ultra-fine powder and particulate range of materials, especially for materials difficult to deal with.Structural principle of the product:The basic screening and manual rotary motion is similar; eccentricity is adjustable from 25 to 40mm; low-speed V-belt drive is adjustable from 120 to 360rpm; each product residence time can swing the screen angle and radial tangential angle toward the driver to adjust the axial direction; therefore establish three levels throwing tumbling motion, the material is uniformly dispersed from the center to the outer edge of the entire screen surface, thereby axially spiral motion to spread, small particles and thus complete the entire screening process; with the movement of the horizontal and vertical acceleration of the particles increases, the mesh size of the particles close to the success of subsequent separation; the larger particles are transported to the outlet side. Controlled by the guide means at the outlet of an adjustable flow rate, the guide means is another factor in controlling the residence time of the material; this process is repeated between each layer of the sieves.
