Vibrating screen is very extensive, involving almost all aspects of life in the processing and manufacturing of all types need to use the shaker.

Vibrating screen mainly used for mining, coal, metallurgy, building materials, refractory materials, light industry, chemical, pharmaceutical, food and other industries.

Vibrating screen in the most concentrator applications, according to the different transmission mechanism, can be divided into the following categories: eccentric vibrating screen, Vibrating Screen, self-centering shaker, resonance screen.

Vibrating screen is the use of a reciprocating rotary shaker type vibration transducer excitation arising from the work. Oscillator on rotating weight makes the screen surface to produce flat whirling vibration, while the lower rotating weight makes the screen surface to produce cone rotary vibration, and its effect is to make the combined effect of the screen surface to produce complex spin-type vibration. Vibration locus is a complex space curves. The curves in the horizontal plane projected as a circular, whereas in the vertical plane of projection is an oval. The regulator, rotating hammer excitation force can change the amplitude. Adjust the upper and lower hammer spatial phase angle, you can change the shape of the curve trajectory of the screen surface and change the trajectory of the screen surface materials.

Working Principle:

Vibrating Screen, Feeding Machine

1) When the vibrating screen work, the two counter-rotating synchronous motor exciter make a reverse excitation force, forcing do mesh sieve driven vertical movement, the material on it by the exciting force periodically thrown forward a range, thus completing the materials screening operations. Appropriate screening sand and gravel quarry, but also for coal preparation, mineral processing, building materials, electricity and chemical industries for product classification purposes. Working part fixed and sliding along the working materials by leaving the materials are screened. Fixed grid screen is more of a concentrator application, generally used for pre-screening coarse crushed or broken before. It is simple in structure, easy fabrication. Do not consume power, the ore can be directly discharged into the screen surface. The main disadvantage is the low productivity, low screening efficiency, generally only 50-60%. Face is a root from the horizontal arrangement of the roll axis constituted shaft has plates, fine material on the gap between rollers or plates from through. And bulk material discharged from the end to move from one end of the drive roller. Concentrator rarely use this sieve. Working part is cylindrical, the entire screen rotation around the cylinder axis, the axis in general downloading into the inclination. Material from one end of the cylinder to the fine level material from the working surface through the cylindrical sieve, coarse-grained material is discharged from the other end of the cylinder. Cylinder Screen speed is very low, steady work, good power balance. But its easy to plug the sieve screening efficiency is low, a small work area, low productivity. Concentrator rarely use it to make screening equipment.

2) The body is oscillating or vibrating in one plane. Its flat trajectory is divided into linear motion, circular motion, elliptical motion and complex motion. Shaking sieve and shaker in this category. When the work place so that the two-motor synchronous reverse a reverse exciter excitation force, forcing mesh sieve driven vertical movement do so by the centrifugal force on the material periodically thrown forward a range, thus completing materials screening operations. Shaking screen is crank linkage as transmission components. The motor drives the eccentric shaft rotation through a belt and pulley, by the rod so that the body is reciprocated along a certain direction.

3) Perpendicular to the direction of movement of the body or suspension strut rod centerline, because the body of the swing motion, the screen surface of the material to a certain speed to move to the discharge end, the material also be screening. Shaking screen compared with the several screens, its relatively high productivity and screening efficiency. The disadvantage is that the power balance is poor. Now concentrator rarely use it, and be replaced by a more rational structure shaker.
