Causes And Solutions of Vibrating Screen Mesh Damage

Date: 2022-07-09     From: Longding     Author: admin

The vibrating screen has a simple structure, stable operation, high screening efficiency, and large processing capacity. The whole equipment has almost no wearing parts except the screen. After the screen mesh is worn during operation, it will cause confusion of materials at all levels and seriously affect the quality of the finished product. The following describes the causes and solutions for the excessively fast crushing of the vibrating screen.

Causes of screen mesh breakage

1. The screen mesh is severely worn.

2. The screen is clogged, which is more difficult to repair. There are various reasons for the screen blockage, such as the material particle size is fine, the mud content is large, and the sieving particle size is small. The porosity is not properly designed and the particles get stuck. Therefore, precautions should be taken before use.

3. If the screen is broken in a regular straight line, there are mainly the following reasons.

A. The screen is not tensioned.

B. The size of the screen is too long, causing the tensioning screw to be insufficiently tightened.

C. The shape and size of the curved edge of the screen do not match the tension plate.

D. Welding fracture of the screen body leads to structural damage to the screen body.

E. The strength of the four springs of the vibrating screen machine is uneven.

F. Defects in the design of the screen or screen machine.

G. There is a problem with the tensioning mechanism of the screen machine, the tension plate is not matched with the screen machine, the tension plate is thin or deformed.

H. The support bar of the screen box is lower than the screen, that is, there is a certain distance between the support bar and the screen.

I. The vibration of the vibrating screen machine is too large.

J. Rubber pads worn or empty.

Solutions

1. When the moisture in the material is more than 5%, the screen surface and screen hole should be selected in a targeted manner.

2. When the moisture content of the material is more than 8%, wet screening can be used.

3. When there are many flake particles in the material, it is necessary to change the material crushing method and the process of different crushing methods.

4. Reasonable adjustment of the tension of the screen is one of the effective measures to reduce the blockage of the screen.
