Lumping at the output of organic fertilizer production lines is a common problem. Here are some solutions:
1. Optimize raw material selection: For example, trace element foliar fertilizers are made from iron, copper, manganese, zinc, sulfate, boric acid, and ammonium molybdate, with magnesium sulfate as the primary additive. Dry raw materials and low humidity in the air will reduce lumps in the produced fertilizer. Ensure the moisture content of the raw materials is low to avoid lumps caused by excessive moisture.
2. Improve production processes: Ensure uniform mixing of raw materials to avoid lumps caused by uneven mixing. Maintain an oxygen concentration >10% and control the temperature within the optimal range of 55-65°C to ensure a thorough fermentation process. Powders such as talcum powder and humic acid can act as a bridge to the granules, and surfactants can also be added to prevent lumps. Improve the uniformity of fertilizer granules and reduce storage pressure.
3. Adjust equipment parameters: Higher room temperature makes it easier for fertilizer to dissolve in its own crystallization water, leading to lumps. Appropriately increasing the granulation temperature (generally above 50°C) can reduce lumps. The greater the applied pressure on the fertilizer, the easier it is for crystals to contact each other, leading to increased agglomeration. Lower applied pressure reduces agglomeration.
5. Use appropriate organic fertilizer equipment: Round granules have a smaller contact area between granules, making them less likely to crystallize and agglomerate. Therefore, if possible, granulation is a method to prevent agglomeration. Using equipment such as a double-spiral compost turner with optimized spiral blade design, such as variable-pitch and combined blades, can break up agglomerated material.
These measures can effectively address the problem of agglomeration in organic fertilizer production lines, improving production efficiency and product quality.
