The capacity of a double roller press granulator produciton line varies considerably, mainly depending on the equipment model, roller diameter and width, material characteristics, and process configuration. The capacity of a single line is usually between 0.5 and 20 tons per hour.

Capacity Classification:

1. Small-scale production line: Suitable for small organic fertilizer factories or laboratories, with a roller diameter of 200-300mm. When processing fermented manure and straw-based organic fertilizers, the capacity is 0.5-2 tons/hour; when processing NPK dry powder mixtures, the capacity is 1-3 tons/hour, with a daily output of approximately 8-48 tons.

2. Medium-scale production line: With a roller diameter of 350-500mm, this is the mainstream choice for organic and compound fertilizer factories. The organic fertilizer capacity is 3-8 tons/hour, and the NPK compound fertilizer capacity is 5-10 tons/hour, with a daily output of up to 40-160 tons, meeting regional market supply needs.

3. Large-scale production line: With a roller diameter of over 500mm, this is mostly configured for large-scale enterprises, equipped with continuous pre-treatment, screening, and shaping systems. The organic fertilizer capacity is 8-15 tons/hour, and the NPK compound fertilizer capacity is 10-20 tons/hour, with a maximum daily output of up to 320 tons, suitable for large-scale production for nationwide distribution.

Key Factors Affecting Capacity:

• Material characteristics: When the moisture content is 5%-15% and the crushing particle size is 80-100 mesh, the molding efficiency is highest, and the capacity can reach more than 90% of the rated value; materials with many impurities and poor plasticity will reduce the capacity by 20%-30%.

• Equipment parameters: The larger the roller width and the more reasonable the rotation speed of the double roller press granulator, the higher the capacity; the roller material (such as wear-resistant alloy steel) can reduce downtime for roller replacement, indirectly increasing effective capacity.

• Process configuration: Production lines equipped with automated batching and continuous screening equipment have a 30%-50% higher capacity than single-machine production.
