In the fertilizer production process, from raw material crushing and mixing to granulation and drying, large amounts of dust are generated at every stage. This dust not only contains active ingredients such as nitrogen, phosphorus, and potassium, but may also carry corrosive substances. Cyclone dust collectors, with their targeted design, are an ideal choice for dust control in fertilizer plants.
The cyclone dust collector’s process is precise and efficient, tailored to the characteristics of fertilizer dust. When the dust-laden airflow from the granulator outlet enters the cyclone dust collector, the tangential airflow design creates a strong rotation within the cylinder. Centrifugal force rapidly propels larger particles (such as unformed fertilizer granules) toward the cylinder wall, where they slide down the conical bottom into the dust hopper. These recovered particles can be reused in production, minimizing raw material loss. For smaller fertilizer dust particles, the optimized airflow trajectory prevents them from escaping with the purified airflow. Even the lighter organic fertilizer dust is effectively captured within the stable centrifugal field. Purified air is discharged from the top outlet, preventing dust pollution in the workshop.
Details specifically designed for the fertilizer industry make it even more practical. Considering the potential for fertilizer dust to absorb moisture and clump, the tapered bottom features a wide angle, coupled with a timed dust discharge mechanism to prevent dust accumulation and blockage. The interior of the cylinder is coated with an anti-corrosion coating to protect against acidic and alkaline elements in the fertilizer, extending the life of the equipment. In compound fertilizer production lines, it can simultaneously process mixed dust generated by different raw materials such as urea and monoammonium phosphate, achieving a consistently high purification efficiency of over 90%. In organic fertilizer production lines, it effectively captures light dust from fermented straw and manure, preventing odor and dust contamination.
Selecting the appropriate cyclone dust collector not only creates a clean environment in fertilizer production workshops, but also recycles effective raw materials and reduces costs.
