Product Description
The BB Fertilizer Blending Mixer is a machine designed to blend two or more pre-granulated fertilizer in specified proportions. Different granules are conveyed via a batching system into the mixer's hopper, which elevates and discharges them into the mixing drum. Rotation of the drum ensures thorough and uniform blending of the granules. Typically batch-operated, continuous production requires the addition of a buffer hopper.
Working Principle
The BB Fertilizer Blending Mixer is primarily employed for the physical blending of granular fertilizer. Through the rotation of its mixing mechanism, the equipment causes fertilizer granules of varying types and nutrient ratios to continuously tumble, convect and cross-mix within the mixing chamber.

Product Advantages
High Uniformity of Mixing
The BB Fertilizer Blending Mixer utilizes either a rotating drum or screw-type agitator design, allowing fertilizer granules to tumble and circulate in multiple directions within the mixing chamber. This ensures homogeneous blending in a short period. With a typical mixing uniformity exceeding 95%–98%, the BB fertilizer blending equipment meets the rigorous demands of compound fertilizer production.
Preservation of Granule Integrity
Raw materials used in BB fertilizer production-such as urea, diammonium phosphate, and potassium chloride-are typically in granular form. This mixer employs a gentle mixing action that minimizes granule breakage, preserving the original particle structure and enhancing the overall quality of the final product.
High Production Efficiency
Designed for simplicity and stable performance, the BB Fertilizer Blending Mixer completes each mixing cycle in just 3–5 minutes. Depending on the model, output can range from 5 to 20 tonnes per hour, making it an ideal solution for medium to large-scale fertilizer plants seeking efficient and consistent blending.
Simple Operation and High Automation
The BB Fertilizer Blending Mixer can be seamlessly integrated with automated batching systems, bucket elevators, and packaging machinery to form a fully automated production line. This integration enables automatic batching, mixing, and packaging-reducing manual labor and significantly boosting overall productivity.
Wide Applicability
One of the standout features of this blending equipment is its ability to blend a wide variety of granular materials, including NPK fertilizers, urea, DAP, MOP, and micronutrient granules. Formulations can be easily adjusted to meet the specific nutritional needs of different crops, offering flexibility and precision in fertilizer production.
Robust Construction and Long Service Life
Built from high-quality carbon steel or stainless steel, the BB Fertilizer Blending Mixer is engineered for durability and long-term performance. Its rugged construction ensures reliable operation, low maintenance requirements, and an extended service life-even under continuous use in demanding production environments.
