YBS-The Φ - type swing screen is a technically mature, classic and universal inertial screening equipment. Its new design concept and unique structure make it the closest screening machine to manual screening operations, achieving almost perfect screening effects for swing screens and having broad application prospects. From the running trajectory of the vibrating body of the screening machine, the swing screen is a nonlinear inertial vibrating screen. Due to the unique structure and working principle, the swing screen is particularly suitable for the classification processing of small particles and fine powder materials. Swing screens can be used for both dry and wet screening, and are widely used in industries such as mining, building materials, metallurgy, casting, abrasives, chemical, light industry, pharmaceuticals, and food for the classification and processing of fine materials.
The screen surface and frame of the swing screen can be made from various materials and processed using different techniques, and can be conveniently stacked in multiple layers for use. The swing screen is a fully enclosed structure, which basically eliminates the phenomenon of material dust overflow and pollution, and can conveniently assume auxiliary facilities such as drying, cooling, dust removal, cleaning, etc
Compared with other inertial screening equipment, the swing screen has the following significant characteristics:
1. Exquisite design and unique structure are beneficial for improving the service life of equipment and reducing operating and maintenance costs.
2. Adopting low frequency and low load conditions, the power system has little effect on equipment and materials
3. The device is relatively small in size, light in weight, easy to install, easy to maintain, and consumes less power, with low noise pollution
4. The relative processing capacity is large, the screening efficiency is high, and the screening accuracy of the swing screen is generally above 95%
5. Fully enclosed structure, with good sealing effect, and basically no material dust pollution phenomenon.
6. The discharge port can be adjusted freely within a 360 ° circumference for easy process layout.
7. The screen mesh is easy to replace and can meet the dry and wet classification requirements of general materials.
The screen surface can be conveniently equipped with a wire mesh device, which can effectively solve the problem of screen blockage.

Structure and working principle

YBS-The Φ - type swing screen generally consists of the following parts:
(1) The vibrating screen screen screen box, (2) isolation device supporting spring group (seat type installation) or spring suspension rod (hanging type installation), (3) power device single axis exciter, (4) drive device asynchronous motor, (5) related supporting accessories, etc
Working principle
From the perspective of the motion trajectory of the vibrating body or screen box of the vibrating screen, the swinging screen, also known as the compound rotating screen, generates an inertial force that changes in a certain pattern around a fixed axis direction by the driving device of the swinging screen. Its essence is the centrifugal force formed by the eccentric mass rotating around the fixed axis. According to the structural characteristics and working principle of the swing screen, its screen surface is generally arranged horizontally or slightly inclined (with an inclination angle of 0 ° -5 °). The working principle of the swing screen is that after the screen machine is started, the vibrating body of the screen machine, namely the screen box, makes approximate circular motion under the action of vibration force. The screen box drives the screen surface to make periodic motion, 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 and becomes the undersized material. The material larger than the screen surface aperture is continuously jumped and discharged from the discharge port, finally completing the screening work.
From the structure and working principle of the swing screen, it can be seen that the rotation direction of its exciter relative to the material direction has two situations: clockwise rotation and counterclockwise rotation. Therefore, in actual screening operations, we can make trade-offs between production capacity and screening efficiency based on specific situations and needs.
