Linear Vibrating Screen common faults and repair solutions

The scope of application of the vibrating screen is very wide. It involves almost every aspect of life. Various types of vibrating screens are used in processing and manufacturing.

Ore Dressing Vibrating Screen is mainly used in mining, coal, smelting, building materials and other industries.

Vibrating screens are most commonly used in ore dressing plants. According to their transmission mechanisms, they can be divided into the following types: eccentric vibrating screens, inertial vibrating screens, self-centering vibrating screens, and resonant screens.

Linear Vibrating Screen

Common faults of Linear Vibrating Screen

1. Poor motor rotation

2. Alien sound

3. Raw materials cannot be discharged automatically

4. The fine mesh is easily damaged

5. The outlet of the discharge frame is cracked

Daily maintenance:

Before startup: check the coarse and fine nets for damage, and whether each set of the ring is locked

When starting: pay attention to whether there is abnormal noise, whether the power supply is stable, and whether there is abnormal vibration

After use: clean up after each use and regular maintenance:

(1) Regularly check the thickness net and spring for fatigue and damage, and whether various parts of the fuselage are damaged due to vibration.

(2) The motor must be replenished with lithium-based grease (ZL-3) in a timely manner for two weeks. Run 1500 hours in total, check the bearings, and replace them immediately if damaged. A maintenance plan for Linear vibrating screen:

During the operation of the vibrating screen, parts are often worn and scratched due to the “hard-to-hard” cooperation relationship of the metal, such as the main shaft bearing position of the vibrating screen is worn out and other faults. After the above problems, the traditional solution of the company is to repair the welding or repair after brush plating, but both have certain disadvantages: the thermal stress generated by the high temperature of the repair welding cannot be completely eliminated, neither the repair welding thermal stress nor the repair thickness. Restricted. At the same time, the metal materials of the product do not have concessions. It can absorb the shock and vibration of the equipment, avoid the possibility of re-wear, and greatly extend the service life of equipment components. value.

The size of the sieve holes for the classification of products with different particle sizes: The size of the grading products (mm) is 2.40, 3.20, 4.00, 4.75, 6.35, 9.50, 12.7 and broken particles, and the corresponding sieve size (mm) is 1.65 , 2.23, 2.92, 3.89, 5.21, 8.97, 11.5, and 1.16. It can be seen that, to control particles of a certain particle size not to pass through the sieve, a sieve diameter smaller than the particle size value should be used.

The classification sieve in the typical granulation process is generally directly fed by a bucket elevator. Due to the vibration classification sieve (SFJZ series), it is easy to cause the material to be concentrated in the middle of the sieve body, the utilization of the sieve surface is low, and the local material layer is too thick, which affects the classification effect. Therefore, it is recommended to set a buffer bucket (with a deflector inside) at the inlet of the classifying screen to make the feeding uniformly along the width of the screen surface.

From the above analysis, we can see that the sieving machinery is widely used in feed processing technology, and the types of selection are different according to different uses. Therefore, we must understand the performance parameters of various types of vibrating screens to better help. We choose the most suitable equipment in the specific design.
