As core equipment in a organic fertilizer production line, a rotary drum granulator requires routine maintenance to extend its lifespan and ensure stable production. First, regularly inspect the transmission mechanism to ensure the proper operation of the motor and reducer. Lubricate the transmission components promptly to ensure smooth operation and prevent wear due to insufficient lubrication.

Maintenance of the support mechanism is also crucial. Regularly inspect the wear of the rolling and sliding bearings and replace any problems promptly to prevent bearing failures from impacting overall equipment operation. Keep the spray system clean and regularly clean the nozzles to prevent clogging that could affect humidity control accuracy, thereby ensuring pellet quality.

Furthermore, after each production run, clean the drum walls of the drum to prevent material agglomeration that could affect the next run. Regularly calibrate the equipment control system to ensure accurate monitoring and adjustment of parameters such as speed, humidity, and temperature. Proper routine maintenance ensures long-term stable operation of the rotary drum granulator, creating greater value for your business.

How to adjust the conveying capacity of the belt conveyor

Adjusting the conveying capacity of the belt conveyor can be achieved through the following methods:

1. Adjust the motor speed: Adjusting the motor speed is one of the common methods to change the conveying capacity of the belt conveyor. The frequency converter can accurately control the motor speed, thereby adjusting the conveying speed.

2. Adjust the drive roller diameter: Replacing the drive roller can significantly change the conveying speed, but the cost is high, the replacement process is more complicated, and professional personnel are required to operate.

3. Adjust the belt tension: By changing the tension of the belt, the friction between the belt and the drive roller is affected, thereby adjusting the conveying speed. Appropriately increasing the tension can increase the friction and speed up the conveying speed.

4. Adjust the feed rate: By adjusting the opening size of the feed hopper or the feed speed, the amount of material entering the conveyor belt can be controlled, thereby adjusting the conveying capacity. Use an adjustable roller assembly The rollers in the adjustable roller assembly can be set at an angle, and the material gathers in the middle of the conveyor belt to prevent spillage.

5. Automatic control: Use the coal inspection modules set at intervals to determine the amount of coal transported on the belt conveyor, so as to accurately control the speed of the previous belt conveyor. At the same time, use the speed sensor to collect whether the speed of the previous belt conveyor after speed regulation is accurately adjusted. In abnormal cases, use the anti-slip protection device to terminate the operation of the belt conveyor, realize the function of controlling the speed of the belt conveyor according to the amount of coal, and reasonably consume electricity and material resources.

Through the above methods, the conveying capacity of the belt conveyor can be effectively adjusted to meet the production needs of different organic fertilizer production lines.
