Problems and Solutions in Tea Sifting Machine
Industrial Tea Sifting Machine Solutions
Ensure the efficiency and quality of the screening process when it comes to tea production. The industrial tea sifting machine is an essential piece of equipment in this process, but various issues can arise during its operation. This article addresses common problems with tea screening machines and provides solutions to optimize their performance.
Problem 1: Uneven Feeding of the Tea Sifting Machine
Reason: The tea sifting machine’s feed port is too narrow, resulting in uneven material distribution across the entire screen surface.
Solution:
- Adjust the width of the feed port to ensure uniform feeding.
- Regularly check the feeding system to ensure stable and even material entry into the tea sifting machine.
Problem 2: Excessive Material on the Screen
Reason: Large feeding volume, blocked sieve holes, and insufficient screen surface inclination.
Solution:
- Adjust the feeding volume to appropriate levels.
- Regularly inspect and clean the sieve holes to prevent blockages.
- Adjust the screen surface inclination to a suitable angle; for instance, an inclination of 20° is often effective in practical applications.
Problem 3: Insufficient Screen Surface Inclination
Reason: A common cause of poor screening performance in circular vibrating screens.
Solution:
- Raise the rear support seat to increase the screen surface inclination.
- Select an appropriate screen surface inclination based on the type of tea and specific screening requirements.
Problem 4: Blocked Sieve Holes
Reason: The feed has high mud and water content, causing materials to stick to the sieve holes.
Solution:
- Clean the sieve holes to ensure they are unobstructed.
- Adjust the water spray volume and screen surface inclination to reduce material adhesion.
Problem 5: Severe Wear of the Sieve Holes
Reason: Prolonged use of the screen.
Solution:
- Repair worn sieve holes.
- Consider replacing the screen if the wear is extensive.
Problem 6: High Bearing Temperature
Reason: Prolonged working hours and insufficient lubrication.
Solution:
- Regularly check the bearings and monitor the temperature, adjusting the working hours to maintain safe temperature levels.
- Ensure proper lubrication of all parts to maintain normal bearing operation.
General Precautions
- Choose appropriate screening equipment and screens based on the type of tea and screening requirements.
- Regularly maintain and service the vibrating screening equipment to ensure its proper operation.
- During the screening process, monitor the screening effect and adjust parameters as needed to achieve optimal results.
By implementing these methods, you can effectively increase the screening output of the industrial tea sifting machine and improve production efficiency.
