Planar gyratory screen

The flat rotary screen (also known as the rectangular rotary vibrating screen) is an efficient screening machine that can meet the requirements of large capacity and high precision. Widely used in chemical industry, metallurgy, mining, feed, food and other industries. Especially suitable for heavy alkali, salt, resin, fertilizer, urea particle size, feed, reduced iron powder, zirconia, ceramics, barite, etc. It has high screening efficiency, high screen utilization rate, easy installation and use, and no pollution. It is an ideal environmentally friendly screening equipment.

Features

1. No vertical vibration, long screen life (6-12 months);
2. Each layer of screen is equipped with a screen anti-blocking and cleaning device. The screen does not block holes and extends the operating cycle. The screening machine continuously cleans the screen in working condition;
3. Due to the adoption of the plane rotation principle, the distribution of materials is significantly improved, thereby increasing the effective utilization of the screen surface, improving screening efficiency, and reducing the powder content in the finished materials;
4. The fully enclosed structure has no dust pollution and improves the working environment of salespersons;
5. The dynamic load on the foundation is very small.

working principle

The Flat rotary screen is also called a reciprocating vibrating screen. The vibration force generated by its driving device is an inertial force that changes in a certain direction around a fixed axis. Its essence is the reciprocating inertial force formed by the rotation of the eccentric wheel around the fixed axis. According to the structural characteristics and working principle of the gyratory screen, the screen surface is generally arranged horizontally or slightly inclined. The working principle of the gyratory screen is: after the screen machine is started, the shaking body of the screen machine, that is, the screen box, reciprocates back and forth under the action of inertial force. The screen box drives the screen surface to shake periodically, so that the materials on the screen surface follow the screen box. During this period, materials smaller than the screen aperture fall to the lower layer through the screen holes and become under-screen materials. Materials larger than the screen aperture are discharged from the discharge port after continuous rolling and jumping motion, completing the screening work.

Application industry

The equipment adopts plane rotary circular motion and has automatic cleaning equipment under the screen. Compared with the traditional linear screen, it has improved screen life, low noise, large screening area, and increased the efficiency from the original 93% to 95% to 98.5%. %. The plane rotary urea screening machine is a new type of screening equipment mainly developed for screening large urea. It is also widely used in screening operations in chemical industry, grain processing, refractory materials, building materials and other industries.
