The npk fertilizer production line mainly includes feeder, disc mixer, chain crusher, granulator, drum dryer, drum cooler, drum screener, finished product warehouse, automatic packaging machine, belt conveyor, Dust settling chamber, heat exchanger, etc. The granulator is an important part of the production of granular npk fertilizer. Common granulators include double roller granulator, drum granulator, disc granulator machine, etc. The granulator is simple to operate, low energy consumption, long service life, Strong wear resistance, has been recognized by many customers, but most customers do not pay much attention to the maintenance of the machine, which leads to machine failure, which seriously affects the service life and production efficiency of the machine.
1. Workers should feed the material evenly, do not change the quantity and quantity, which will affect the quality and output of pellets.
2. Check all parts frequently to see if the screws are loose, if they are loose, they should be firm in time.
3. The oil needs to be changed frequently. If the oil is not changed for a long time, oxides will be produced, which will enter some materials and affect the service life of the machine.
4. The wearing parts should be replaced frequently during the fertilizer granulation process. The long-term use of the machine will cause the wearing parts to wear out, and the parts must be replaced before the wearing parts are completely unusable.
5. Do not overload the machine for a long time. Machines, like humans, also need rest. Reasonable rest of the machine will prolong the service life.
