In the fertilizer manufacturing industry, a device is uniquely changing the rules of granulation: the double roller press granulator. Unlike traditional granulation methods, it requires no binder, produces no wastewater, and requires no drying process. This “dry granulation” technology is quietly leading a green revolution in fertilizer production.

Imagine two precisely coordinated rollers, like dancing partners, rotating against each other to create the miracle of granulation. Raw material powder is fed between the rollers and, under high pressure, is instantly formed. This process is fast, efficient, and remarkably quiet.No clamor, no flying dust, only smoothly operating equipment and uniformly produced pellets.

The unique feature of the double-roll extrusion granulator lies in its simple, aesthetically pleasing “one-step” process. Compared to other granulation equipment, it eliminates the need for complex post-processing. No dryer is required to remove moisture, as the entire process requires no liquid binder; nor is a complex temperature control system necessary, as the pelletizing process is physically performed at room temperature. This simple yet sophisticated design concept makes it exceptionally energy-efficient and environmentally friendly.

However, this does not mean that the double-roll extrusion granulator stands alone.At the front end, a fertilizer crusher pulverizes the raw materials to the appropriate fineness; a mixer ensures even distribution of the various components; and at the back end, a drum screener still needs to select qualified products. The entire system is like a streamlined and efficient team, with each member playing an irreplaceable role.

The advantages of this granulation method are impressive. The granules it produces are strong and resistant to breakage, making them easy to store and transport. The product has a uniform particle size and a neat appearance. More importantly, it maintains the chemical properties of the raw materials, making it particularly suitable for granulating heat-sensitive materials. From compound fertilizers to organic fertilizers, from minerals to chemical products, the double-roller extrusion granulator demonstrates excellent adaptability.
