In the granulation of powder materials in industries such as fertilizers, chemicals, and pharmaceuticals, the double roller press granulator, as a high-performance fertilizer granulator, has become a core production piece for many companies due to its unique technological advantages, and is also a flagship model for many fertilizer machinery manufacturers. Compared to traditional granulation equipment, it is based on a dry, room-temperature process, achieving comprehensive breakthroughs in production efficiency, environmental performance, and finished product quality.

Energy saving and environmental protection are its most prominent advantages. This equipment uses a dry granulation process, eliminating the need for additional drying and cooling processes, saving energy consumption from fuel heating and steam supply, and significantly reducing energy consumption during production. At the same time, the entire production process produces no wastewater or exhaust gas emissions, and requires no additional wetting agents, avoiding fertilizer clumping problems caused by binders and meeting industry requirements for green production, saving companies environmental governance costs.
High granulation rate and high-quality finished products are key to its market dominance. The double-roll extrusion granulator achieves granulation through the extrusion force of two opposing rotating rollers. The die overlap can reach 100%, and the pelletizing rate can reach up to 95%. The resulting pellets have high strength, are not easily broken during transportation and storage, and effectively maintain nutrient integrity. Furthermore, the equipment can precisely control the particle size, producing spherical and oblate spherical pellets within the range of 3.2-6.0mm. It can also process multi-element compound fertilizers, producing full, rounded pellets with uniform nutrient distribution, meeting the customized needs of various industries.
Its wide adaptability to raw materials expands its application boundaries. Whether it's fertilizer raw materials such as ammonium sulfate and potassium chloride, chemical powders such as catalysts and pigments, or industrial waste such as fly ash, this equipment can achieve efficient granulation. It is particularly suitable for powdery materials with a moisture content of less than 10%, and can fill the technological gap in the granulation of rare earth and potash compound fertilizers, playing an important role in multiple fields.
Low operating costs and high stability help enterprises reduce costs and increase efficiency. The parts of the equipment that come into contact with raw materials are made of stainless steel, and the roller skin is made of high chromium alloy with a service life of over 800 tons and a low failure rate. At the same time, it adopts a quick-release connection method, which makes maintenance simple and fast. The modular design also makes the equipment occupy less space and can be flexibly assembled into a continuous production line of 1-50 tons, taking into account both the small-capacity needs of small and medium-sized enterprises and the large-scale production of large factories.
