Plane rotary screen
Plane rotary screen equipment has the advantages of reasonable design, simple structure, stable operation, fully closed structure, no dust, plugging hole, anti-stick mesh, etc. Especially for hygroscopicity strong, viscous, easy to plug holes and sticky mesh urea screening more obvious. Due to the principle of plane rotating motion, the ratio of static and static of the equipment and the dynamic load of the foundation are effectively reduced.

Product Introduction
Plane rotary screen supplier production of the equipment using plane rotary vibrating screen up and down vibration, automatic cleaning equipment, compared with the traditional linear screen, improve the life of the screen, small noise, screening area is large, the rate from the original 93 ~ 95 to 98.5, good prospects for promotion. Plane rotary urea screening machine is mainly for large urea, soda, quartz sand screening development of a new screening equipment, is also widely used in chemical, grain processing, refractory materials, building materials and other industries of screening operations.
Features:
- 1. Strong structure, lasting continuous work;
- 2. Super production capacity (2-150t /h), and high screening accuracy;
- 3. Flick the ball to clear the net and effectively prevent the blockage of the net hole;
- 4. The service life of the screen is very long, is the life of the screen used by the ordinary vibrating screen 5-1 00 times;
- 5. Applied to the classification of 12mm to 40 micron particles, can be used as many as 5 layers, the production of up to 6 particle size segments;
- 6. Three kinds of spring clamp and screen side pull mode, easy to disassemble, easy to replace the screen.
Working Principle
Trajectory
Planar rotary motion: the screen box makes a uniform circular motion (the trajectory is circular or elliptical) in the horizontal plane, which is driven by the eccentric mechanism. This kind of movement makes the material spread spirally on the screen surface, accompanied by a slight up and down jump.
Inclination design: the screen surface usually has an inclination of 1°-5°, using gravity to assist the material to flow from the inlet end to the outlet end.
Material separation process
- Stratification and permeability screening:After the material enters the screen surface, under the action of rotary movement, small particles are subject to centrifugal force, inertial force and gravity of the combined effect of downward settlement, contact with the sieve holes and pass through (through the sieve).
- Large particles can not pass through the screen holes, gradually move to the edge of the screen surface, and finally discharged from the upper outlet.
- Uniform distribution:The rotary motion makes the material continuously dispersed and tumbled, avoiding accumulation and improving the screening efficiency.
- Multi-level sieving:Multi-layer screen (such as the upper layer of large holes, the lower layer of small holes) can achieve multi-level classification, and materials with different particle sizes are discharged from the discharge port of each layer respectively.
Motion parameter adjustment
- Eccentricity: adjust the rotary radius, which affects the spreading speed of the material and screening precision.
- Rotation speed: too high speed will lead to material splash, too low will reduce the screening efficiency, need to be optimised according to the material characteristics.
- Sieve surface inclination: control the material flow rate, the larger the inclination, the faster the flow rate but shorten the screening time.
Application Industry
Plane gyratory sieve machine is mainly for large particles of urea, soda ash, quartz sand screening development of a new type of screening equipment, but also widely used in chemical, food processing, refractory materials, building materials and other industries of screening operations.
