Repair and maintenance of trommel screen

Preface: The trommel screen, also known as the cylindrical rolling screen, is an indispensable part of garbage screening and mining machinery. In order to ensure the efficient operation and extend the service life of the trommel screen, maintenance and repair work are essential. The following is a detailed description of the maintenance and maintenance of the trommel screen:

A. Maintenance of the trommel screen

1. Noise repair: The trommel screen makes a clicking noise, which may be caused by loose bolts. At this time, the bolts or other fasteners need to be re-tightened. The trommel screen makes too much noise when working, which may be due to insufficient roller lubricant or serious roller wear. At this time, lubricant needs to be added or the roller needs to be replaced.

2. Rotation direction repair: If the trommel screen rotates in the wrong direction, it may be that the motor power cable is connected incorrectly. At this time, any two power cables in the junction box need to be replaced.

3. Slow start repair: If the motor starts slowly, it may be that the conveying volume exceeds the allowable value or the motor is overloaded or the torque is insufficient when the motor starts. At this time, the conveying volume needs to be readjusted.

4. Gearbox heating repair: If the gearbox is hot, it may be due to lack of lubricant or poor ventilation in the box. At this time, lubricant needs to be added and the heat dissipation of the adjustment vents needs to be checked.

5. Motor heating maintenance: If the motor heats up, it may be that the motor cooling time is too short, the working environment of the motor is greater than 40 degrees, the motor is overloaded, the motor connection line is loose, and the motor star-triangle connection is incorrect. At this time, you need to clean the heat sink of the motor, check whether the fan impeller is working properly, ensure the smoothness of fresh air, reduce the load, tighten the connection, and reconnect after inspection.

6. Screen hole blockage maintenance: If the garbage cannot move forward on the production line, it may be that the trommel screen is blocked. At this time, it needs to be cleaned up in time. If the trommel screen cannot operate normally and the motor cannot operate normally, it may be that the screen hole is blocked. At this time, it is necessary to clean the garbage blocked at the screen hole in time.

7. Bearing heating maintenance: If the bearing is hot, it may be that the lubricant is insufficient or the bearing is severely worn. At this time, you need to add lubricant or replace the bearing.

B. Maintenance of trommel screen

1. Clean the various parts of the trommel screen

a. Clean the drum and screen regularly to avoid impurities from clogging and maintain the screening effect.

b. Clean the spring regularly to maintain its elasticity and ensure the normal operation of the machine.

c. Clean the debris and residual materials inside the equipment regularly to prevent blockage and affect efficiency.

d. Regularly remove dust and dirt from the surface of the equipment to keep the equipment clean and extend its service life.

2. Lubricate the trommel screen

a. Regularly check the lubrication of the bearings, and add lubricating oil appropriately according to the usage to ensure smooth operation of the machine.

b. Regularly check the oil level and use appropriate lubricating oil to reduce friction loss and improve running stability.

3. Check the trommel screen

a. Regularly check whether fasteners such as bolts and screws are tightened to prevent equipment failures caused by loosening or falling off.

b. Regularly check important components such as bearings and gears to ensure their normal operation, and replace damaged parts in time to avoid the expansion of faults and affect production safety.

5. Monitor the abnormal sound of the trommel screen: During operation, pay close attention to the sound and vibration of the trommel screen. If there is an abnormality, there may be a problem inside the equipment, such as loose or worn parts. At this time, the machine should be stopped for inspection and repair in time.

6. Storage of trommel screen: When the trommel screen is not used for a long time, it should be stored in a dry and ventilated environment, and sprayed with rust inhibitor to prevent moisture and rust.

7. Operation specifications of trommel screen

a. Operators should be familiar with and master the operating procedures, operate according to the prescribed steps, and avoid equipment failure caused by improper operation.

b. Pay attention to timely adjust the technical parameters such as speed and feed amount to meet the production needs of different materials and improve production efficiency and quality.

8. Safety protection of trommel screen: set up protective covers and warning signs to ensure that there is no debris piled around the equipment. These measures can ensure the safe operation of equipment and personnel.

PS: The repair and maintenance of trommel screens involves many aspects, and professional personnel are required to conduct regular inspections and maintenance. Through scientific repair and maintenance measures, the efficient operation and extended service life of the trommel screen can be ensured.
