Sand aggregate vibrating screen
As the screening equipment commonly used in sand and gravel aggregate production lines, the circular vibrating screen has the characteristics of simple structure, stable performance, high screening efficiency, and so on. The vibration is generated by the vibration exciter driven by the motor. Because of the circular vibration track of the screen surface, the material on the screen surface is constantly overturned and loosened. Tianfeng vibrating circular screen has complete models, simple operation, excellent material selection, processing technology, and long service life.
In the process of sand aggregate production, screening equipment is required to classify and store coarse and fine aggregates. There are many types of vibrating screens, including circular vibrating screens and linear screens. As sand aggregate screening equipment, circular vibrating screens are commonly used. The types are complete, the number of layers on the screen surface varies from 1-5, and the processing capacity varies from 70-1000 tons/hour, which can meet the needs of different users and can be used widely.
The circular vibrating screen structure
It is mainly composed of a vibration exciter, screen box, support device, transmission device, etc
Vibration exciter - a single motor is used to drive two groups of vibration exciters of the screen frame to generate vibration;
Screen box - the screen frame is composed of the screen frame and screen plate, the screen frame is composed of the side plate, channel steel, beam, reinforcing plate, etc. riveted, and the screen plate, as the direct bearing body of materials, is woven from steel;
Support devise - spiral spring support, low noise;
Drive device - V-belt drive is used to drive the eccentric block to rotate, and the vibration frequency can be changed by adjusting the number of eccentric blocks;
working principle
The motor drives the vibration exciter to generate vibration. When the whole equipment is upward, the spring recovers and extends, and the material on the screen is thrown up and becomes loose. When it is downward, the spring is compressed, and the material falls back onto the screen. The equipment vibrates continuously up and down. The material is thrown up and down several times, the material smaller than the screen size is separated, and the material larger than the screen size is discharged from the end, so as to achieve the purpose of screening coarse and fine aggregate.
Performance characteristics
1. The screen with long service life is made of steel braid, the side plate is made of Q345B steel plate, and the riveted link is used to increase the overall strength of the screen body;
2. The number of layers on the screen surface varies from 1 to 5, and 6 different specifications of finished materials can be screened at the same time;
3. The side plate with stable operation is milled and drilled by a gantry milling and boring machine, with installation accuracy;
4. Easy to adjust The frequency and intensity of vibration can be adjusted by increasing or decreasing the angle and number of eccentric blocks;
5. The 3YKZ40100 round vibrating screen with a processing capacity of 4 m * 10 m can reach a processing capacity of 1000 tons per hour, which is applicable to the screening operation of the large sand aggregate production line;
Operating principle of swing screen
YBS series vibrating and swinging screen is a low-frequency rotary vibrating screen imitating manual shaking. The principle is that the instantaneous motion is the combination of the radial displacement and the circular motion with this displacement as the axis (spiral motion). The exciter, which can adjust the eccentricity, produces a nonlinear three-dimensional motion, and the material also produces the same motion similar to manual operation, so as to achieve the purpose of screening. A more ideal screening effect can be obtained by combining it with screening accessories. It is suitable for materials with spherical, cylindrical, flaky, or even irregular shapes that are easy to block the screen and require precise screening.

Technical characteristics of swing screen
1. The design is exquisite and the structure is good, which is conducive to improving the service life of the equipment and reducing the operation and maintenance costs.
2. Low frequency, low load operation, the power system has little effect on equipment and materials.
3. The equipment is relatively small in size, light in weight, simple in installation, convenient in maintenance, low in power consumption and 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, good sealing effect, and basically no material dust pollution.
6. The discharge port can be adjusted freely within 360 ° circumference for process layout.
7. The screen is easy to replace and can meet the dry and wet classification requirements of general materials.
8. The screen surface can be conveniently equipped with a screen cleaning device to solve the problem of screen surface blockage.
Up to 5 times the output per unit area; It can be separated into 6 levels, and the screening accuracy is up to 90% - 95%; With the use of a silicone rubber ball and ultrasonic screen cleaning device system, the screen hole will not be blocked. Closed dedusting, the acceleration is 4.5 times lower than that of the vibrating screen, and the service life of screening parts is improved while maintenance is reduced; Noise<75dB. Optimize the gravity balance, and the dynamic load of the foundation is low.
