The application and types of Vibrating screen bearings for cement plants

Oct 27, 2023

The vibrating screen operates based on the vibration motor's excitation principle. It causes materials to be thrown onto the screen surface to achieve screening. 

Vibrating screens have the advantages of simple structure, smooth operation, and easy maintenance. They are widely used in raw material screening, product grading, and cement production line processes. It can select different screening modes according to the characteristics of the material and screening requirements to meet the needs of other occasions.

In addition, the cement vibrating screen mesh adopts a modular design and is easy to replace and clean. In general, vibrating screens used in cement plants play an essential role in ensuring cement quality and output.

The vibrating screen is a commonly used equipment in cement plants, and the bearing is one of the critical components of the vibrating screen. It supports the screen frame and vibrator and withstands the impact and friction caused by materials and vibration. Therefore, selecting appropriate bearings is significant to the regular operation of the vibrating screen and extending its service life.

Types and characteristics of vibrating screen bearings

Tapered roller bearings

The tapered roller bearing is a standard vibrating screen bearing. It can bear radial and axial loads and withstand significant impacts and vibrations. Tapered roller bearings have a small friction coefficient and can provide a higher limit speed and lower temperature rise, thereby ensuring the stable operation of the vibrating screen.

Spherical roller bearings

Spherical roller bearings are suitable for supporting vibrating screens with non-linear trajectories. Models such as Spherical roller bearings 22316E, 23318VA405

wait. It is designed with a spherical raceway inside, which can automatically adjust the axis position to adapt to different shapes of screen frames. Spherical roller bearings have a large contact area and high load-bearing capacity and can withstand the impact and friction of materials on the screen surface.

Cylindrical roller bearings

Cylindrical roller bearings are suitable for supporting vibrating screens with linear trajectories. Its rolling elements are cylindrical, with a small friction coefficient and a high limit speed. Cylindrical roller bearings can provide stable support and long service life when bearing radial loads.

Selection of vibrating screen bearings

When selecting vibrating screen bearings, you need to consider the following factors:

Load type and size: Different bearing types have different load-bearing capacities. Selecting a suitable bearing type according to the actual load type and size is necessary.

Usage environment and working conditions: Different usage environments and working conditions have different requirements for bearing materials and surface treatment methods. Selecting suitable materials and surface treatment methods is necessary for the situation.

Speed and limit speed: The speed and limit speed of the bearing has a significant impact on the regular operation and service life of the vibrating screen and need to be selected according to actual needs.

Size and accuracy level: The size and accuracy level of bearings significantly impact the performance and life of machinery and equipment and need to be selected according to actual needs.

Cost and cost-effectiveness: When selecting bearings, consider price and cost-effectiveness and choose highly cost-effective products.

Maintenance of vibrating screen bearings

To extend the service life of the vibrating screen bearings, regular maintenance, and upkeep are required:

Regularly check the lubrication of the bearings to ensure good lubrication and prevent dry friction and sticking.

Regularly check the wear of the bearings. The bearings should be replaced in time if severe wear or damage is found.

During use, avoid overloading or sudden impact to prevent damage to the bearings.

When shutting down, the bearings should be cleaned and kept clean to prevent the entry of debris and dirt.

Workers should back up important vibrating screen bearings and maintain them regularly to prepare for emergencies.

The vibrating screen is a commonly used equipment in cement plants, and the bearing is one of the critical components of the vibrating screen. Choosing the suitable bearings is significant to the regular operation of the vibrating screen and extending its service life. Factors such as load type and size, usage environment and working conditions, speed and limit speed, and accuracy level must be considered when selecting and using vibrating screen bearings. At the same time, regular maintenance and upkeep is also one of the essential measures to extend the service life of bearings.
