The BB fertilizer blender is a core piece of equipment specifically designed for the production of blended fertilizers. BB fertilizer——also known as bulk-blended fertilizer——is produced by scientifically proportioning and mechanically mixing two or more types of granular straight fertilizers. A complete BB fertilizer production line typically comprises equipment such as a fully automated batching system, a lifting conveyor, a specialized BB fertilizer mixing system, and an automatic quantitative packaging scale.
The working principle of the BB fertilizer blender is straightforward, yet attention to detail is crucial for success.
Once the equipment starts, the drive motor powers the mixing mechanism. Materials enter the mixing drum through the inlet, where they are continuously lifted, tossed, and propelled by spiral mixing blades or paddles.
A key feature of the BB fertilizer mixer is its ability to operate in both forward and reverse directions: forward rotation mixes the materials, while reverse rotation facilitates automatic discharge. Completing this sequence concludes a single production cycle. The mixing speed is typically regulated between 20 and 50 revolutions per minute; this range ensures effective blending while preventing granule breakage.
Standard-compliant equipment achieves ≥95% mixing uniformity, whereas ordinary, simple mixers typically reach only 75%–85%. With the latter, finished fertilizer is prone to localized nutrient imbalances (excess or deficiency), leading to uneven crop growth.
The low-speed mixing design minimizes the impact and breakage of hard granules. The finished product generates minimal dust, preventing dust-related clogging of sealing machines during subsequent packaging operations.
The mixing chamber is designed to minimize material residue, allowing factories to switch between multiple fertilizer formulas in a single day without worrying about cross-contamination from the previous batch affecting the new product's composition.
The drive mechanism is robust and wear-resistant with few consumable parts; workers at rural fertilizer plants can operate the equipment after only brief training.
The equipment integrates seamlessly with automatic batching systems, conveyors, and quantitative packaging scales to create a fully automated BB fertilizer production line, thereby saving on labor costs associated with manual feeding and material transport. If you plan to set up a complete production line, you can view the equipment list for fully automated blended fertilizer production lines.
BB fertilizer mixers are designed exclusively for processing granular raw materials. The list of compatible materials includes:
Granular urea, potassium chloride, potassium sulfate, diammonium phosphate (DAP), and monoammonium phosphate (MAP) base granules;
Granular borax, zinc fertilizers, silicon fertilizers, magnesium fertilizers, and various granules containing secondary and trace elements;
Slow-release coated fertilizers, humic acid granules, microbial agent granules, and soil conditioner granules.

The horizontal mixer features high load capacity and rapid, uniform mixing; it is suitable for various granular and powdered materials, ensures smooth discharge, consumes little energy, and offers easy operation and hassle-free maintenance.
The vertical disc mixer ensures uniform mixing and accommodates a wide range of fertilizer raw materials; it operates stably, offers rapid discharge, and allows for easy maintenance.
The double shaft paddle mixer is equipped with two rotating shafts; the paddles vigorously turn and blend the materials to ensure a uniform mix, and the machine is commonly used for the pre-treatment of organic and compound fertilizer powders.
