China high capacity Gratory screener 

Gyratory screener
RA series  Gyratory screen is one of the main products of Shanghai, shanghai runnest  M&E technology Co., Ltd.Is the introduction and absorption of advanced technology in Europe and the United States after the screening of a new type of high precision screening machine. The machine has the advantages of high efficiency, high utilization rate of screen, small space occupation, convenient installation, large capacity, easy for production facilities, no pollution, low noise

Main structure of  gyratory screen
The  gyratory screener is mainly composed of a screen box, a driving device, a sieve frame, a support frame and a vibration reducing device, etc. the structure design features are mainly divided into two points:
1, the driving device comprises a drive motor, and a locking sleeve, Wan Xiangzhou, lock nut, washer and sleeve components, the sleeve is fixed on the screen box, the driving shaft and set the drive through the locking sleeve is connected and fixed its position in cone sleeve. Compared with the prior art, the utility model has the advantages of advanced and practical structure, stable and reliable performance, convenient installation and debugging, etc..
2, the screen box includes screen frame, screen, screen lattice, spring card and bouncing balls and other components, the screen frame is fixed on the frame by the characteristics of grid and the mesh and used to clean up the surface of the screen is composed of jump. The screen frame is installed on the upper and lower two layers of screen, screen by setting the screen grid on the periphery of the card spring tension in the lattice, bouncing ball is arranged in the sieve box.

Working principle of plane gyratory screen
The working principle of  gyratory screener is mainly uses the eccentric mechanism makes the sieve surface uniform reciprocating rotary motion, the material and the surface contact time, mesh cutting of the powder material produced, thus screening risk screening, screening of high precision, large output, screen on the material structure itself less destructive. The screen box with 4-9 degree is driven by the driving box, and the moving track of the moving track is a horizontal circular motion at the feed end, and gradually becomes an ellipse motion in the length direction.
The material that is fed into the feed inlet can be distributed evenly on the whole sieve surface under the action of the circular movement of the screen. In order to make the material with smaller particle size below the screen, and the larger size of the material to the end of the movement of the material. In the process of moving, because there is no stirring and vertical beating, so the smaller particles always close to the screen surface, can be over the screen at any time. The discharge end of the sieve, approximate motion into reciprocating linear motion, the sieving effect gradually weakened, so that the sieve size greater than the particles quickly to the discharge direction, until discharged out of the machine, the complete material screening. During screening, the elastic ball constantly beating effectively prevent blocking materials to ensure the high efficiency of sieve, sieve, balance block transmission to the inertial force before and after the sieve box during the movement direction of the balance, so as to ensure the smooth movement of the screen.
Main features of plane gyratory screen
1, the  gyratory screen production is 1-5 times of the ordinary screening machine, high yield, low energy consumption;
2, fully enclosed structure, dust is not flying, the use of emphasis on balance, so that the screening machine vibration is small, low noise, in line with environmental protection requirements;
3, the unique screen mounting structure, more convenient to clean the screen, high utilization rate, long service life;
4, plane rotary screen with a combination of circular, elliptical, straight line three kinds of motion trajectory, the screening effect is good, does not destroy the original structure of the material, suitable for a variety of materials screening and screening;
