Gyratory Vibrating Screen is another new type of screening equipment developed by introducing advanced foreign technology. This machine has the advantages of reasonable design, simple structure, stable operation, fully enclosed structure, dust-free dyeing, anti-blocking holes, anti-stick nets and so on. In particular, urea screening with strong hygroscopicity, high viscosity, easy to plug holes and sticky net is more obvious. Due to the use of the principle of plane rotary motion, the dynamic-static ratio and basic dynamic load of the equipment are effectively reduced. The equipment adopts a plane rotary vibrating screen to vibrate up and down, and there is an automatic cleaning device under the net. Compared with the traditional linear screen, it improves the life of the wire mesh, reduces noise, and has a large screening area, which improves the efficiency from the original 93-95 98.5, the promotion prospects are good. The plane rotary urea screening machine is a new type of screening equipment developed for the screening of large urea, pure radon, and quartz sand. It is also widely used in screening operations in the chemical, food processing, refractory, and building materials industries.
Movement characteristics
a. No vertical vibration, long screen life (6-12 months);
b. Each layer of screen is equipped with a screen anti-blocking cleaning device. The screen does not block the holes, extending the operating cycle. The sieving machine cleans the screen continuously under the working condition.
c. Due to the principle of plane rotation, the distribution of materials is significantly improved, thereby increasing the effective utilization of the screen surface, ultimately improving the screening efficiency and reducing the powder content in the finished material
d. The fully enclosed structure is free of dust pollution, which improves the working environment of the salesperson.
f, the dynamic load on the foundation is very small
Working principle
The
plane rotary screen equipment adopts reciprocating rotary motion mode and low-inclined screen surface, so that the material can produce circular motion at the feed port to quickly achieve material dispersion and layering, and realize elliptical motion in the middle of the screen box, which can perform well. Material sieving allows small particles to pass through the sieve quickly, and realizes approximately linear movement at the discharge end, so that particles larger than the size of the sieve openings are quickly moved in the direction of discharge until they are discharged outside the machine to complete the whole screening of the materials. Three motion trajectories are adopted: circle, ellipse and straight line.
Application scope of gyratory screen
Chemical industry: melamine, sodium citrate, etc.
Fertilizer: raw material sieving and fine sieving of final products, including amine carbonate, amine nitrate, phosphate, potassium hydroxide urea, compound fertilizer and other compounds.
