In the fertilizer production line, the fertilizer crusher is one of the key equipment, responsible for crushing the raw material into a fine degree suitable for granulation. However, in the process of long term operation, the crusher is prone to overheating due to high load work, affecting the life of the equipment and production efficiency. How to effectively prevent the overheat of the crusher is the key to ensure the stable operation of the fertilizer granulator.
1. Control equipment running time to avoid long-term high-load operations
The continuous operation of the fertilizer crusher for a long time will cause the temperature of the motor, bearings and other components to rise, and even burn the motor. It is recommended to arrange the working time reasonably, stop the machine every 4-6 hours for inspection, and properly cool the equipment to prevent the temperature from being too high.
2. Regular cleaning to reduce material accumulation
During the crushing process, some fine powder may remain in the crushing chamber, affecting heat dissipation. If the accumulation of too much material, will lead to the internal blockage of the crusher, so that the motor load increases, the temperature rises rapidly. Therefore, the inside of the crusher should be cleaned regularly to ensure smooth ventilation.
3. Choose the right grinder to match the production needs
Different materials are suitable for different types of shredders, such as:
• Semi-wet material crusher: suitable for high humidity materials, reduce clogging and high temperature problems.
• Chain crusher: suitable for npk and other hard raw materials, wear resistance, good heat dissipation.
• Cage crusher: suitable for medium hardness materials, uniform crushing, low energy consumption.
Selecting the right crushing equipment can reduce the risk of overheating and improve production efficiency.
4. Strengthen lubrication and reduce mechanical friction
The bearing, blade and other parts of the mill will produce a lot of friction during high intensity work, resulting in higher temperature. Regular addition of lubricating oil can effectively reduce friction, reduce the risk of equipment overheating, and extend the service life.
5. Ensure motor ventilation and heat dissipation
If necessary, install a cooling device, such as a cooling fan or water cooling system, to improve the heat dissipation capacity of the device and avoid motor damage due to high temperature.
