If the circular vibrating screen does not start or the amplitude is too small, there are several steps you can take to troubleshoot and resolve the issue. Here's what you can do:
Check the power supply: Ensure that the vibrating screen is properly connected to a power source and that the power supply is functioning correctly. Check for any loose connections or tripped circuit breakers. If the power supply is not working, address the power issue before proceeding further.
Inspect the motor: The motor is responsible for generating the vibration in the circular vibrating screen. Check if the motor is running or if there are any unusual sounds coming from it. If the motor is not running, it could be due to a faulty motor, loose wiring, or a malfunctioning motor starter. In such cases, you may need to replace the motor or consult a professional for repairs.
Examine the vibration exciter: The vibration exciter is a component that generates the required vibration amplitude. If the amplitude is too small, check the exciter for any mechanical issues. Look for loose or damaged parts, worn-out bearings, or misalignment. If any of these problems are detected, you may need to repair or replace the exciter.
Check the screen deck: Inspect the screen deck for any obstructions, such as debris or material build-up. Clear away any blockages that may impede the movement of the screen. Additionally, make sure the screen mesh is properly tensioned. Loose or damaged screen mesh can result in reduced amplitude. Adjust or replace the screen mesh as necessary.
Lubrication: Ensure that all moving parts, such as bearings and joints, are adequately lubricated. Lack of lubrication can cause friction and reduce the efficiency of the vibrating screen. Follow the manufacturer's recommendations for lubrication intervals and use the appropriate lubricant.
Consult the manufacturer's manual: The vibrating screen should come with a manufacturer's manual or documentation. Refer to the manual for specific troubleshooting steps and maintenance guidelines. It may provide additional information or instructions tailored to your particular model.
Seek professional assistance: If the issue persists or you are unsure about performing the troubleshooting steps yourself, it is advisable to contact the manufacturer's customer support or a qualified technician. They will have the expertise and knowledge to diagnose and resolve the problem safely and efficiently.
Remember, when dealing with machinery, always prioritize safety. Disconnect the power supply before conducting any inspections or repairs, and follow proper safety procedures throughout the troubleshooting process.
