In the NPK (nitrogen phosphorus potassium compound) fertilizer production line, the roller extrusion granulator is one of the key equipment, and its normal operation directly affects the overall efficiency and product quality of the production line. Regular maintenance is crucial to ensure the long-term stable operation of the equipment. Here are some specific suggestions for maintaining the roller extrusion granulator:

Daily inspection and cleaning

Cleaning up residues: After the end of production every day, it is necessary to remove the residual materials inside and outside the roller extrusion granulator, especially the gaps between the rollers and around the cutting blade, to avoid the accumulation of foreign objects that may affect the next operation.

Check lubrication: Confirm if the lubrication system is functioning properly, regularly lubricate moving parts such as bearings and gears to reduce wear.

Regular maintenance

Roller inspection: Regularly check the wear of the roller surface, and if necessary, polish or replace it to maintain the granulation effect.

Transmission components: Check the condition of chains, belts, and gearboxes, tighten loose parts in a timely manner, and replace severely worn components.

Electrical system: Check circuit connectors and switches to ensure no corrosion or damage, and maintain safe and stable power supply.

performance testing

Pressure regulation: Adjust the pressure between the rollers according to actual production needs to achieve the best granulation effect.

Particle quality: Regularly inspect the particle size, strength, and uniformity of granulation products, evaluate equipment performance, and make timely corrections.

Train employees

Organize regular training to familiarize operators with the operating procedures and safety rules of the equipment, understand common troubleshooting methods, and enhance their sense of responsibility and technical abilities.

Record management

Establish a comprehensive equipment maintenance file, recording the details of each maintenance, the problems discovered, and the solutions taken, providing a basis for future reference.

Follow the manufacturer's guidance

Strictly follow the user manual and maintenance guidelines provided by the equipment manufacturer, carry out standardized operation and maintenance, and extend the service life.

Through the maintenance strategy of the above system, not only can the good condition of the roller extrusion granulator be maintained, but the occurrence of sudden failures can also be significantly reduced, ensuring the continuous and stable operation of the NPK fertilizer production line, thereby improving overall production efficiency and product quality. A reasonable maintenance plan is a manifestation of the concept of preventive maintenance, which helps enterprises build a sustainable production system.
