The actual screening process of the vibrating screen is: after a large number of broken and scattered materials with different particle sizes and mixed sizes enter the screen surface, only a part of the particles contact the screen surface. Due to the vibration of the screen box, the material layer on the screen is loosened, which further expands the existing gap of large particles. Small particles pass through the gap and transfer to the lower layer or conveyor.
Vibrating screen bearing
According to the structure and working principle of screening machinery, there are roughly the following categories:
1. The working face of roller screen is composed of rolling shafts arranged horizontally.
2. The working face of roller screen is composed of rolling shafts arranged horizontally.
3. The plane motion screen body is a plane swing or vibration.
The working conditions of the shale shaker are relatively harsh. With high rotating speed, high vibration, humidity, dust particles and other harsh environments, the bearing of the shale shaker is very important among the components of the shale shaker, and is one of the key components. The bearing capacity, impact resistance, self-lubrication and deformation resistance should be taken into consideration when selecting.
Generally, symmetrical self-aligning roller bearing and cylindrical roller bearing are selected, and large clearance bearing is selected to overcome the expansion volume change caused by large heat generation. Self-aligning roller bearing mainly bears radial load force, and is relatively suitable for working under heavy load and vibration load conditions. SKL cylindrical roller bearings include N type, NU type, NJ type, NF type and NUP type in terms of type selection. When assembling the vibrating screen, the appropriate vibrating screen bearing shall be selected according to the actual requirements and the direction and strength of the load bearing.
