Round Vibrating Screen
Vibrating screen is the use of vibrator excitation produced by the reciprocating vibration and work. The upper rotary weight of the vibrator makes the screen surface produce plane cyclotron vibration, while the lower rotary weight makes the screen surface produce conical rotary vibration, and the combined effect makes the screen surface produce compound rotary vibration. Its vibration trajectory is a complex spatial curve. The curve is projected as a circle on the horizontal plane and an ellipse on the vertical plane. The amplitude can be changed by adjusting the excitation force of up and down rotating heavy hammer. By adjusting the space phase Angle of the upper and lower hammers, the curve shape of the motion trajectory of the screen surface and the motion trajectory of the material on the screen surface can be changed.
Circular vibrating screen is a kind of large-scale mining vibrating screen, which is mostly used for screening coal, limestone, gravel, metal or non-metal ore and other materials, which is related to the safety of the staff. There is no trivial matter about the safety, which requires the production process of circular vibrating screen to be standardized and normalized, the product quality must be qualified and meet the national regulations, and the circular vibrating screen is in operation We should observe whether there are abnormal changes in the screen machine from hearing and vision, such as whether there is abnormal sound, whether the material deviates, whether the screen is loose and blocked, whether the working condition of the vibration exciter and screen box is abnormal, and check the bearing temperature at the same time.
Circular vibrating screen is a kind of high-precision powder screening equipment, its low noise, high efficiency, only 3-5 minutes to replace the screen, fully closed structure. Suitable for screening plastic powder material filtration.
Swing sieve with vertical motor as vibration source, the two ends of the motor installed eccentric weight and the motor rotation into horizontal, vertical, inclined three-dimensional movement, and then transferred to the surface of the screen. Adjust the upper and lower phase angles to change the trajectory of the screen surface.
The circular vibrating screen is a new type of vibrating screen with multi layers and high efficiency;
Low stress shock absorption spring is used to reduce noise;
It adopts super heavy bearing with large oil gap, low operating temperature and long service life;
The structure of the screen box and the frame with high strength is adopted;
Wear resistant rubber screen can be provided to make the materials stuck in the screen hole jump out and prevent the screen hole from blocking;
It has the advantages of large processing capacity, strong universality of parts and convenient maintenance.
