Fertilizer Mixing & Granulation Equipment
-
Spray granulator is a key piece of fertilizer equipment that integrates spraying, granulation, and drying into a single machine. It can be used as a standalone unit or combined with other fertilizer equipment.
The simultaneous spraying and granulation process, combined with continuous drum operation, significantly boosts production capacity, making it suitable for large-scale industrial manufacturing.
The equipment can handle a wide variety of liquid formulations, allowing for the production of diverse compound fertilizer products.
The granules produced by the spray granulator have excellent solubility and nutrient-release properties. This enhances nutrient absorption by crops and improves overall fertilizer utilization.
The spray granulation and drying sections feature a unique lifting combination scoop design with toothed tips. These scoops continuously lift the material, forming an even curtain. The slurry is sprayed into the drum through pneumatic nozzles, adhering uniformly to fine particles within the curtain. These particles then gradually dry and granulate. A motor and gearbox drive the granulation drum at a stable, appropriate speed, while a hot air system provides the necessary heat to accelerate drying and solidification.

The shell is made of Q235 steel with an internal rubber liner. The spray nozzle is made of stainless steel.
Our experts are on hand to help you with any questions you may have about fertilizer equipment.
The various raw materials of fertilizers go through the entire process of feeding, crushing, mixing, conveying, granulation, drying, cooling, screening, coating, and packaging.
We recommend our vertical pan mixer. It's designed to efficiently mix powdered or granular materials like cement. Its compact footprint requires minimal floor space, which is ideal for retrofits and factory upgrades. This mixer offers stable performance with low power consumption and a simple structure that is easy to clean and maintain.
The double shaft mixer is an excellent choice for high-volume production. With two shafts working simultaneously, it can process large amounts of material in a short time. Its adjustable blade angles and cutting gaps ensure a consistent and thorough mix for materials with different particle sizes, densities, and flow characteristics.
Our spray granulator is a great solution. It's a key piece of fertilizer equipment that combines spraying, granulation, and drying in one unit. It can be used alone or integrated with other equipment. The spray granulator is highly adaptable to various liquid formulations, enabling you to produce a wide variety of compound fertilizer products.
