When selecting an organic fertilizer granulator for a small-scale organic fertilizer produciton line, factors such as raw material characteristics, production scale, granulation process, equipment performance, and cost should be comprehensively considered. Here are some suggestions:
1. Choose based on raw material characteristics: For high-moisture, high-viscosity materials, such as livestock and poultry manure and biogas residue, an extrusion granulator is recommended. This type of equipment uses high pressure to form pellets, eliminating the need for additional drying and is suitable for viscous materials. For medium- and low-moisture materials, such as fermented straw and mushroom residue, a rotary drum granulator or disc granulator can be selected, which utilize the rolling agglomeration principle to form pellets. For materials with high fiber content, such as wood chips, equipment equipped with a powerful crushing device is required.
2. Choose based on production scale: For small farmers or pilot plants, a disc granulator is recommended, offering low investment (approximately 20,000-50,000 yuan) and simple operation. For medium-sized enterprises (daily production of 5-20 tons), a rotary drum granulator is more efficient, capable of continuous operation, and combined with drying equipment for streamlined production, with an initial investment of approximately 80,000-150,000 yuan.
3. Choose based on the granulation process: Disc granulators are suitable for a variety of organic fertilizer raw materials, offering high pelletization rates (over 93%), intuitive operation, and simple control. However, they have a low processing capacity per unit. Double roller press granulator are suitable for small organic fertilizer production lines, effectively reducing energy consumption and working with high-moisture and high-viscosity materials.
When selecting an organic fertilizer granulator, it is recommended to first communicate with the equipment supplier to understand its specific performance and applicable range, and then conduct a comprehensive evaluation based on your own production needs.
