Fertilizer production equipment info

The granulator is the core equipment in NPK fertilizer production , and its operational stability directly affects product quality and capacity. In actual production, granulators often experience malfunctions such as poor granulation, abnormal equipment vibration, and discharge blockage.  Troubleshooting requires a precise approach based on process characteristics. The following are common troubleshooting methods and key solutions. Poor granulation is a typical malfunction of NPK fertilizer granulator s, manifested as loose granules and uneven particle size. First, check the raw material ratio. If the moisture content of nitrogen, phosphorus, and potassium raw materials is too high or too low, it will lead to insufficient binding. The moisture content should be adjusted to a reasonable range of 20%-30%. Second, check the mixing uniformity. If the raw materials are not evenly mixed, resulting in insufficient binder content in some areas, the mixing blades should be inspected to ensu...

In the production of NPK fertilizer s, uneven mixing is a frequent problem that affects product quality.  This directly leads to an imbalance in nutrient distribution in the finished product, resulting in detection errors exceeding 1%, which in turn causes uneven crop growth, reduced fertilizer utilization efficiency, and even fertilizer-related disputes. To completely solve this problem, it is necessary to trace the root causes and implement targeted technical control measures. The main causes of uneven mixing are concentrated in three areas: firstly, shortcomings in the mixing process, such as insufficient mixing time (less than 5 minutes) or worn blades preventing thorough mixing; secondly, excessive differences in raw material particle size, such as potassium fertilizer not being crushed to 80 mesh or finer, making it difficult to uniformly mix large particles with fine powder; and thirdly, non-standardized batching procedures, where the feeding order is not adjusted according ...
