In the field of pellet production, disc granulator and flat die granulator are two mainstream equipments. Choosing the right model can greatly improve production efficiency. The two have different focuses in applicable scenarios and performance characteristics, and need to be accurately selected in combination with material characteristics and production needs.

The applicable materials are significantly different. The disc granulator is good at handling high-humidity materials, especially suitable for granulation scenarios where binders need to be added in organic fertilizer and compound fertilizer production lines. It has strong adaptability to sticky materials such as clay and sludge. The flat die granulator is the "nemesis" of crude fiber materials. Low-bonding materials such as sawdust, rice husks, and straw can be directly granulated under its extrusion without the need for additional binders. It is more suitable for the production of biomass fuels, feed pellets, etc.
Each performance characteristic has its own advantages. The disc granulator rolls the material into balls through the rotation of the tilted disc. It has a high granulation rate, high roundness of particles, uniform and adjustable particle size, and is suitable for scenes with high requirements for particle appearance. The flat die granulator uses a pressure wheel to squeeze the material through the die hole to form the granules. The granules are hard and not easy to break. The particle size range is wide. Although the roundness of the granules is slightly inferior, they are resistant to storage and transportation losses.
The key is to adapt to production needs. If you pursue continuous large-scale production, the disc granulator can be equipped with a conveyor belt to realize automated assembly line operation, reduce manual intervention, and is suitable for large-scale production enterprises. The flat die granulator is more suitable for small and medium-sized production. The equipment occupies a small area, is flexible to move, and can cope with small batch production of multiple varieties. The material change and cleaning time is short, which is much lower than the disc granulator.
According to the material characteristics, particle requirements and production scale, the equipment can be maximized. Choose a disc granulator for high-humidity and sticky materials, and a flat die granulator for coarse fiber and low-viscosity materials. Choose the right equipment to make the fertilizer production line efficient and economical, and speed up and increase the efficiency of production.
