What is a trommel screen Replacement?

As a common screening equipment, drum screen is widely used in various production lines. During the use of drum screen, the screen, as a key component, needs to be replaced regularly due to wear, blockage or corrosion to ensure the screening effect. The following is a detailed answer to the replacement of drum screen (mainly refers to the replacement of screen):

1. Preparation before replacing the screen

Preparation of new screen: Make sure there is a new screen available for replacement, and the specifications of the new screen (such as size, mesh size, etc.) must match the original screen to ensure the screening effect.

Tool and material preparation: Prepare necessary tools and materials, such as screwdrivers, wrenches, lubricating oil, etc., for use during disassembly and installation.

Safety preparation: Turn off the power of the drum screen to ensure safe operation. Operators need to wear protective equipment and follow operating procedures to ensure the safety of themselves and the equipment.

2. Disassemble the old screen

Operate according to the manual: Disassemble according to the manual or relevant operating instructions of the drum screen to avoid damage to the equipment or safety hazards.

Protect the old screen: Pay attention to protecting the disassembled old screen for subsequent processing or recycling.

Clean up debris: clean up the debris and dust generated during the disassembly process to ensure a clean working environment.

3. Install the new screen

Check the specifications: ensure that the size and specifications of the new screen are consistent with the old screen to avoid improper installation.

Flat installation: install according to the structural characteristics of the drum screen to ensure that the screen is flat, wrinkle-free and firmly fixed.

Check and adjust: after the installation is completed, check whether the screen is flat and undamaged, and make necessary adjustments and corrections.

4. Debugging and inspection

Turn on the power: turn on the power of the drum screen to observe whether the new screen is operating normally, whether there is any jamming or abnormal sound.

Check the screening effect: check whether the screening effect of the screen meets the expectations, and make appropriate adjustments if necessary.

5. Replacement cycle

The replacement cycle of the drum screen is affected by many factors, including material characteristics, screen material, screening accuracy requirements, equipment operation time and strength, etc. Therefore, it is impossible to give a fixed replacement cycle. But in general, it can be considered comprehensively based on the following factors:

Trommel Screen

Material characteristics: When handling abrasive, sticky or wet materials, the screen will wear faster and may need to be replaced more frequently.

Screen material: Steel wire screen has a lower cost, but its wear and corrosion resistance is average; stainless steel wire mesh has good corrosion resistance and certain wear resistance, and its service life is relatively long.

Screening accuracy requirements: In industries with extremely high screening accuracy requirements, such as electronic materials, fine chemical raw materials, pharmaceuticals, etc., the screen needs to be checked and replaced more frequently.

Equipment operation time and intensity: When the equipment is running continuously for a long time or the equipment is running at a high intensity such as high feed speed, feed volume and drum speed, the screen will wear faster.

The replacement of the drum screen is a comprehensive process involving multiple links and factors. In order to ensure the screening effect and the normal operation of the equipment, the screen needs to be checked and replaced regularly.
