Vibratory separator is a kind of high precision fine powder screening machine.Its low noise, high efficiency, fast network change only 3-5 minutes, completely closed structure; In addition, equipment operators can set the speed of material passing through the screen and the direction of movement on the screen to provide maximum processing capacity and screening efficiency for any screening product, whether wet or dry, heavy or light, coarse or fine. The working principle of rotary vibrating screen
The working state of the vibratory separator effectively mimics the screening machinery of human manual movement and process. Its unique design cleverly combines the sieve (planar circular motion), the Dustpan (to, the parabolic movement), the material in the equipment to do the horizontal and throwing three-dimensional rolling movement, from the Center to the outer edge evenly dispersed, with the spiral movement to the axial propagation. When the spinning sieve works, the motor drives the Sieve machine to do the space three-dimensional curve, this curve is projected as a circle on the plane. The projection on both vertical surfaces is elliptical. Adjusting the eccentric speed of the motor can change the movement trajectory of the material on the sieve surface, so that the sieve body produces a flat vertical composite vibration, to achieve the purpose of screening.
The material is feed from the middle of vibratory separator, and the movement distance of the material on the screen is basically the same, which can guarantee a very accurate screening process. The radial angle and tangential angle of the spinning sieve make the material move involute on the screen, and its design allows the material to walk through the phase on a smaller area. For long roads, the mesh time of the material is longer than that of other types of sieves. Adjusting the radial angle and tangential angle can adjust the accuracy and yield of the sieve.
The structure of rotary vibrating screen
The rotary vibrating screen is mainly composed of screen cover, screen frame, motor (vibration source), rubber spring, base, etc.
1. The screen cover is composed of an inlet and an oblique cone, the lower end of which is connected to the screen frame. The screen cover and screen frame are connected by clamps, and there is a sealing pad between the screen cover and screen frame.
2. The screen frame is rolled with steel plate. The upper and lower ends of the screen frame are provided with a - receiving ring, and the lower end has an internal flange ring, which is used to fix the screen and the screen cleaning system.
3. Vibration source is composed of motor and motor support
4 rubber spring mainly plays a role in limiting the screen machine following the rotating shaft rotation.
5. The base is the foundation of the screen machine. The main drive shaft of the screen machine is fixed on the pyramid chassis of the screen machine through the bearing.
Vibratory separator is a commonly material classification equipment, which is designed to meet the requirements of high efficiency and high screening accracy. Rotary vibrating screen is suitable for all powders and granular materials, especially for materials which are difficult to sieve. Rotary vibrating screen is widely used for sugar, rice powder, paints, aluminum powder, ore, quartz sand, wastewater, etc.
