advantages
1

The side plates of the screen and the reinforcing ribs (angle steel) are all riveted with HUCK bolts without any welds. This ensures that the side plate has no stress concentration and cracking, improves the strength and rigidity of the side plate, thereby improving the reliability of the equipment.

2

The vibrating screen exciter beam and the screen frame beam adopt a box-shaped beam structure with reinforcing ribs inside to improve the rigidity and strength of the screen machine and reduce the weight of the whole machine. Thereby improving the efficiency of the whole machine and reducing power consumption.

3

All the mating surfaces of beams and vibrating screen exciter beams are processed by automatic CNC machine tools before assembly. The non-processed surfaces of all components are sandblasted and painted with epoxy resin. All gaps will be filled with waterproof glue. Make sure it does not rust.

4

The surface of the screen frame beam is sprayed with 6mm thick polyurethane wear-resistant coating to provide the service life of the beam.

5

The vibration parameters are set reasonably to avoid the natural frequencies of each level of the screen body and reduce the impact of resonance;

6

The vibrating screen has a simple and compact structure, high rigidity, high strength, balanced force distribution, and large safety factor;

7

The overall weight of the screen body can be reduced to the greatest extent under the conditions that meet the requirements of all aspects of the vibrating screen. Make the whole vibrating screen have high strength, light weight, large processing capacity, low power consumption, high vibration intensity and high screening efficiency;

8

The connecting parts of the equipment are assembled with noise reduction technology, so that the noise of the whole screen is low when working, and the noise within 1m from the equipment is less than 80db;

9

Multi-section, multi-inclination screen surface structure is conducive to material ejection and reduces the hole blocking rate.

10

Adopting domestic brand screen surface configuration, small block type setting, fixed rail seat, convenient and quick installation and replacement, and high screening efficiency;

Each vibrating screen is fully assembled before leaving the factory and undergoes an idling test run for 8 hours. The amplitude and frequency are tested with a VB instrument, and the operating curve is drawn with the coordinate method to verify the reliability;

the frequency analyzer is tested for 72 hours During the period, the natural frequency is detected, and the collected data is uploaded to the computer for finite element analysis to ensure that each vibrating screen can achieve efficient and safe production.

WORKING PRINCIPLE OF VIBRATING SCREEN

Working principle

Horizontal straight screen and banana screen

The motor is powered on and starts, and the driving force is transmitted to the main drive shaft through the belt drive mechanism and the secondary shaft system. The main drive shaft drives the vibrating screen exciter to generate linear vibration force. The direction of the excitation force is at an angle of 45° to the horizontal. The linear vibration force cyclically acts on the screen body continuously to make the screen body vibrate on the buffer spring. At the same time, the buffer spring reduces the dynamic load of the screen body on the support foundation of the screen machine and reduces the noise of the screen machine. The screen body drives the screen surface to vibrate synchronously. The force is transmitted to the material on the screen, and the impact material is stratified before being thrown up on the screen surface and classified according to the specified particle size. The material is continuously buffered from the feeding chute to the receiving plate, and is screened through the screen surface. The bottom material is discharged into the under-screen chute, and the over-screen material is discharged into the discharge chute.

High frequency dehydration vibrating screen

Two vibrating motors with the same parameters installed symmetrically on the excitation beam rotate synchronously and reversely when connected to electricity, and each generates centrifugal force of equal magnitude. The components of the two forces in the vertical vibration direction are opposite to cancel each other, and the components in the parallel vibration direction are consistent with each other. The linear vibration force is superimposed to form a linear vibration force. The linear vibration force cyclically and continuously acts on the screen body to make the screen body vibrate on the buffer spring. At the same time, the buffer spring reduces the dynamic load of the screen body on the support foundation of the screen machine. The screen body drives the screen surface to vibrate synchronously. , The force is transmitted to the material on the screen, the impact material is thrown up on the screen surface for dehydration, the material is continuously input from the feeding chute, and the dehydration treatment is carried out through the screen surface. Material chute.
