Introduction to Fine Rotary Screen: An efficient and precise flat rotary screen consists of a machine base and a screen body with elastic balls installed on the screen surface. There are gantry hangers on the outer sides of both ends of the machine base, and hanging ropes are connected to the hanging rings of the machine base to lift the machine base horizontally. A set of driving devices is installed on one end of the machine base, and a transmission box is installed on the driving device. The transmission box is connected to one end of the feeding port of the screen body through an active shaft, a driven shaft, and its eccentric block. The other end of the screen body is inclined downward by 3-8 degrees and hung on the gantry hanger at the other end with a hanging rope.

EfficientPrecision flat rotary screenIt has the advantages of reasonable design, simple structure, smooth operation, fully enclosed structure, dust-free dyeing, anti blocking holes, anti sticking mesh, etc. Especially for urea screening with strong moisture absorption, high viscosity, easy blockage of pores, and sticking to the mesh, it is more obvious. Due to the use of the principle of planar rotational motion, the dynamic to static ratio and foundation dynamic load of the equipment have been effectively reduced. This device uses a flat rotary vibrating screen to vibrate up and down, and there is an automatic cleaning device under the net. Compared with traditional linear screens, it improves the service life of the wire mesh, reduces noise, and has a large screening area. The efficiency has been increased from the original 93-95 to 99, and the promotion prospects are good. The flat rotary urea screening machine is a new type of screening equipment mainly developed for the screening of large urea particles, and is also widely used in precise grading and screening operations in industries such as metallurgy, mining, chemical, pharmaceutical, building materials, grain processing, refractory materials, etc. It is a new type of high standard screening equipment, which has high screening efficiency, high screen utilization rate, stable and reliable operation, is not easy to crush qualified particles, and is pollution-free. It is an ideal environmentally friendly screening equipment.

Characteristics of fine rotary screen:

(1) The self-cleaning effect is excellent, and each layer of the screen is equipped with a screen anti blocking cleaning device, which does not block the screen;

(2) Large processing capacity reduces the powder content in finished materials, which is 10 times that of ordinary sieves;

(3) High utilization rate of screen mesh, no vertical vibration, long service life;

(4) Fully enclosed structure with no dust pollution, improving the working environment for operators.

Fine rotary screen is suitable for industries:

(1) Chemical industry: fertilizers, soda ash, calcium powder, resins, melamine, etc;

(2) Food: Sugar, salt, starch, milk powder, etc;

(3) Metallurgy: metals, magnetic materials, etc;

(4) Building materials: coatings, refractory materials, etc.

Working principle of fine rotary screen:

followScreening machineFrom the trajectory of the shaking body or sieve box movement,Flat rotary screenAlso known as reciprocating screen, the vibration force generated by its driving device is an inertial force that changes in a certain regularity around a fixed axis and direction. 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 rotary screen, its screen surface is generally arranged horizontally or slightly inclined. The working principle of the rotary screen is as follows: after the screen machine is started, the shaking body of the screen machine, namely the screen box, moves back and forth under the action of inertia force. The screen box drives the screen surface to shake periodically, so that the material on the screen surface moves in a directional jumping motion together with the screen box. During this process, the material smaller than the screen surface aperture falls to the lower layer through the screen aperture, becoming the undersized material. The material larger than the screen surface aperture is discharged from the discharge port after continuous rolling and jumping motion, and finally completes the screening work.

followFlat rotary screenIt can be seen from the structure and working principle that the eccentric track of the transmission mechanism has a crucial impact on the material movement trajectory and the retention time of the material on the screen surface, which has the opposite effect on the processing capacity and screening efficiency of the screen machine. In view of this, in actual screening operations, we can make trade-offs between production capacity and screening efficiency according to specific situations and needs.

Material movement of fine rotary screen:

For the same or similar configuration, the flat rotary screen has a higher inertia than the general onevibrating screenWith higher processing capacity and screening efficiency, the essence of this model is that it can artificially control the movement trajectory and retention time of materials on the screen surface. In a finite space, due to the non-linear curves of velocity and acceleration of material movement trajectory, there is more contact between the material and the screen surface in the machine filter, which naturally increases the screening rate.
