Common Problems with NPK Fertilizer Granulator Machines
During the granulation process of NPK compound fertilizer production line s, various problems can arise due to factors such as raw material characteristics, operating procedures, and equipment maintenance, directly affecting the quality of fertilizer granules and production efficiency. This article summarizes four common problems with granulation machines and, considering the diverse NPK fertilizer formulations and the need to prevent nutrient loss, provides simple and easy-to-implement solutions to help farmers and fertilizer plants achieve efficient production. Uneven and inconsistent granule size is the most common problem, often caused by improper raw material matching or unreasonable parameter adjustments. The moisture content of NPK mixed raw materials needs to be controlled between 15% and 25%. Too high moisture content can lead to clumping and oversized granules, while too low moisture content makes granulation difficult. Simultaneously, extrusion granulators require...
