circular vibrating screen introduction:
Circular vibrating screen is a multi-layer, high-efficiency new vibrating screen. The circular vibrating screen adopts a cylindrical eccentric shaft exciter and an eccentric block to adjust the amplitude. The material sieve has a long flowing line and many screening specifications. It has a reliable structure, strong excitation force, high screening efficiency, low vibration noise, strong and durable, maintenance Convenient and safe to use, the round vibrating screen is widely used in product classification in mining, building materials, transportation, energy, chemical and other industries. According to the material products and user requirements, high manganese steel woven screen, punching screen plate and rubber screen plate can be used. All kinds of screen plates can meet the different requirements of the screening effect. This series of circular vibrating screens is seat-mounted. The inclination of the screen surface can be adjusted by changing the height of the spring support.

Working principle:
The crushed material group with different particle sizes passes through the single-layer or multi-layer sieve with uniformly distributed holes multiple times, and the process of dividing into several different levels becomes sieving. The particles larger than the screen hole are left on the screen surface, which is called the sieve on the screen surface, and the particles smaller than the screen hole penetrate the screen hole, which is called the sieve on the screen surface. The actual sieving process is: after a large amount of mixed materials with different particle sizes and mixed thicknesses enter the sieve surface, only a part of the particles are in contact with the sieve surface. Due to the vibration of the sieve box, the material layer on the sieve is loosened, so that the large particles already exist The gap is further expanded, and small particles take the opportunity to pass through the gap and transfer to the lower layer or transport aircraft. Due to the small gaps between small particles, large particles cannot pass through, so the original disordered particle group was separated, that is, the particles were stratified according to the size of the particles, forming the arrangement rule of small particles below and coarse particles above. The fine particles that reach the sieve surface are smaller than the sieve holes, and finally the coarse and fine particles are separated to complete the screening process. However, there is no sufficient separation. When sieving, a part of the sieve is usually left on the sieve. When fine particles pass through the sieve, although the particles are smaller than the sieve pores, they are different in the degree of difficulty in sieve penetration. The particles with similar material and sieve pore size are more difficult to pass through the sieve, and the gap between the particles through the lower layer of the sieve is more difficult.

Main Features
1) Large processing capacity and high screening efficiency.
(2) The vibrator adopts bearing thin oil lubrication and external block eccentric structure. It has the characteristics of large excitation force, low bearing load, low temperature and low noise. (The bearing temperature rise is less than 35 °).
(3) The overall disassembly and assembly of the vibrator is convenient for maintenance and replacement, which greatly shortens the inspection cycle. (It only takes 1 to 2 hours to replace the vibrator).
(4) The side plate of the screen machine adopts the whole plate cold work, no welding, high strength and long service life. The connection between the beam and the side plate adopts torsion shear high-strength bolt connection, no welding, and the beam is easy to replace.
(5) The screen machine uses rubber springs to reduce vibration. Compared with metal springs, it has the advantages of low noise, long service life, stable over-common vibration area, and small dynamic load at each pivot of the screen machine.
(6) The flexible coupling is used to connect the motor and the exciter, which has the advantages of long service life and small impact on the motor.
