Have you ever wondered how those uniform little pellets in your fertilizer bag or chemical containers are made? It’s not magic—it’s the brutal, beautiful physics of Double Roller Granulation.

Unlike other methods that require adding water and then hours of drying, this machine uses Dry Extrusion Technology. It simply squeezes dry powder between two counter-rotating rollers until they bond into solid shapes.

Why we’re obsessed with this process:

No Heat, No Water: Energy-efficient and perfect for heat-sensitive materials.

The "Crunch": There’s something incredibly satisfying about watching loose dust enter the rollers and emerge as perfect, high-density granules.

Versatility: From potassium chloride to complex NPK blends, it handles it all with raw mechanical force.

Whether you're into industrial engineering or just here for the satisfying crunch of heavy machinery, you have to appreciate the simplicity of this design.

Roller granulator, the instant of dry extrusion.

The material is compressed, shaped, and broken under high pressure. The entire process uses no excess water or heat, yet the granules are excessively uniform.

A granulator is a machine that mechanically processes bulk or wet raw materials into uniform granules or pellets through cutting, compression, extrusion, or spraying. It is widely used in industries such as feed, fertilizer, fuel, biomass, plastics, pharmaceuticals, and food, facilitating subsequent drying, tableting, packaging, or conveying.

Working Principle The core of a granulator is a high-speed rotating screw or die roller. The screw's compression and friction increase the temperature and pressure of the raw materials. As the material enters the annular die, it is forced into shape and cut by cutting tools to form pellets. In a wet granulator, the raw materials are first moistened with water or steam. The water is then rapidly evaporated under high temperature and high pressure, causing the water to expand and form porous, low-moisture granules.

Main Types Screw granulators: Suitable for powdered or granular raw materials, commonly used in feed and fertilizer production. Disc granulators: Utilize centrifugal force and gravity to cause fine particles to roll and bond on a disc surface. They are suitable for granulating chemical raw materials such as sulfur. Double-cone, fluidized bed, and other processes: Specialized processes for varying viscosity or particle size requirements.

Applications Feed pellets: Process raw materials such as grain and soybean meal into pellets that are easy to store and feed. Fuel pellets: Convert biomass such as straw and sawdust into fuel pellets that can replace coal for applications such as home heating and power generation. Fertilizer pellets: Wet or dry granulation improves fertilizer flowability and application uniformity. Plastics and pharmaceuticals: Granulate raw materials into uniform pellets before injection molding or tableting, improving processing efficiency and product quality.

Advantages Uniform particle size facilitates subsequent process control. Adjustable moisture content meets different drying or combustion requirements. Relatively low energy consumption, especially with disc pelletizers, which utilize centrifugal force to achieve natural bonding. High adaptability: A variety of pellet sizes can be produced by replacing molds or adjusting the speed.
