Gyratory vibrating screen is a kind of device famous for its large capacity ,high efficiency and high precision. It is universally used in chemical and metallurgical, mining, feed, food and other industries., especially for heavy alkali, salt, resin, fertilizer, urea granule size, feed, reduced iron powder, zirconium oxide, ceramic, barite, etc.
Working principle:Square gyratory screen is also called reciprocating screen, if see from the motion trail of screen box. The vibratory force produced by its driving device is the inertial force twining along the dead axle, the direction of which is change according to a certain regular. The essence of square swinging screen is the reciprocating inertial force formed by the rotation of eccentric wheel winding the dead axle. According to the structure characteristics and working principle of swinging screen, the screen surface is arranged with level or incline (angle of inclination is 0-5 degree). After turn on the swinging screen, the screen box take reciprocating movement under the inertial force, screen box drives screen surface to make periodic shaking, which makes the materials on the screen surface to make directional jumping movement with the screen box. During the period, the material less than the screen aperture falls to under layer, the material bigger than the screen aperture make jumping movement, discharged from the coarse outlet.
1.Good sealing, balance weight can provide slight vibration and low noise,environmental protection.
2.No block,good self cleaning device
3.Combination of Circle, elliptic, linear motion, high screening effect .Suitable for various material screening
4.Equipped with automatic tension and automatic cleaning sieve net installation system which can make the screen mesh long service life and high efficiency , change the screen mesh conveniently.
5.Reinforced base ensure balance operation of the equipment.
6.Used for powder or granule feed screening and grade, can also be used for voidance of raw materials in feed factory.
