Rotary drum granulator is an important machine in compound fertilizer making factories, which is used for large scale fertilizer materials granulating. Besides compound fertilizer granulating, it also can be used for organic fertilizer manufacturing line. But we learned some customers found the problem of high temperature of the gearing. That may affect the performance of the whole machine. So what are the reasons? And how to solve this problem?

Bearing Circle of Rotary Drum Granulator

At first, the lubricating oil is insufficient. The lack of lubricating oil will lead to the increase of friction between bearing and the machine, which will cause excessive temperature. So adding enough lubricating oil before using the granulator is very important.

Secondly, if the lubricating oil is not clean, the bearing will be affected by dust. With the increasing dust, the gearing becomes rough. So the temperature of the gearing will rise continuously and burn down. If the fertilizer making environment is nor clean, this problem will be more serious. So the cleaning of the bearing and factory environment is very important.

Thirdly is the damage caused by long-term use. If the granulator is used for a long time, the parts may be aged, and the damage is inevitable. So when the parts are damaged, it’s better to replace them in time. That not only can prolong the granulator working life, but also can make sure the high performance to bring you wonderful profits.

The last reason may be unreasonable installation. Under normal conditions, the bearing is on the center line of the granulator. If you install the machine by mistake, the bearing temperature rising is obviously. To help you make fertilizer efficiently, we can provide you free installation guidance. If the problem can’t be solved, we can also arrange our technician to your site.
