3-4 Tons Per Hour Double Roller Extrusion NPK Fertilizer Production Line with 22kw Power for Oval Shape Granules

NPK Compound fertilizer production line is widely applied to produce compound fertilizer with capacities ranging from 5,000-200,000 tons/year. This equipment can granulate various materials including NPK, NP, ANP, DAP, MAP, CAN, SSP and others into compound fertilizer particles in a single processing line. It is specially designed for manufacturing compound fertilizers with different concentrations and types, such as organic fertilizers, inorganic fertilizers, biological fertilizers and magnetic fertilizers. The system primarily produces oval particles with diameters ranging from 2mm to 6mm.

Compound fertilizer contains two or all three of the essential plant nutrients—Nitrogen, Phosphorus, and Potassium—as well as microelements such as Boron, Manganese, Copper, Zinc, and Molybdenum. Raw materials can be in powder or bulk form, primarily including:

The NPK compound fertilizer production line typically includes 7 processes: batching, grinding, mixing, granulating, screening, coating, and packaging. Batching, mixing, granulating, and screening are essential processes, while others are optional based on production capacity requirements.

• Produces NPK fertilizer, DAP and other materials into compound fertilizer particles
• Primarily used for producing spherical particles with diameters ranging from 1-3mm
• Wide range of raw material compatibility with easy-to-operate production formulas for high, medium, and low grade NPK fertilizer
• Mature production technology with stable equipment operation and high efficiency
