The core of the reliability of the vibrating screen lies in the material control and stress control under harsh working conditions - the material selection is first of all high-quality and anti-damage, the welding is preferably fine wire technology, the cutting and bending process is precisely stress-relieved, and the anti-corrosion treatment is carried out in two ways to break through the bottleneck of life.

In the gravel production line, the vibrating screen is a very important auxiliary equipment. This article mainly introduces the factors that affect the reliability of the vibrating screen:

1. Material control of the vibrating screen

First, due to the harsh working environment of the vibrating screen, the material selection of the vibrating screen is of great significance, especially the key parts. However, the quality of materials on the market is uneven. Manufacturers should choose high-quality raw materials to make vibrating screens and inspect the selected materials. Secondly, manufacturers should select materials according to customer requirements and archive the material certificates for further analysis.

2. Manufacturing precision control of vibrating screen

In order to control the manufacturing precision, in addition to shape and position control and roughness control, it is more important to control the welding deformation of the welding components. At present, vibrating screen manufacturers generally use carbon dioxide gas shielded welding, which is low in cost and easy to install. The use of fine welding wire can reduce welding deformation, and the weld has good rust resistance and crack resistance. Therefore, choosing the appropriate welding method according to the actual situation and adopting the appropriate welding process are the basis for solving the deformation problem of the vibrating screen.

3. Internal stress control and anti-corrosion treatment of the vibrating screen

First, in the production process of the vibrating screen deck base, various internal stresses will be generated, mainly thermal stress generated by cutting, stress generated by bending of bent parts, and welding stress of welded parts. When the vibrating screen vibrates, these stresses will have a damaging effect. Similarly, during the operation of the vibrating screen, the deck base will also be corroded. Under the action of corrosion, stress concentration will be caused, resulting in reduced fatigue strength. Secondly, manufacturers should take effective measures to control thermal stress, such as plasma cutting. Furthermore, for the control of bending and welding stress, eliminating annealing is a more effective method, which can also control deformation. But the disadvantage is that this method will increase investment.
