2-4T/H Medium-Capacity NPK Fertilizer Production Line
Production Process Overview
NPK raw materials (nitrogen/phosphorus/potassium sources) are precisely weighed, mixed uniformly, then fed into the granulator with binder spraying. After granulation, materials undergo drying, cooling, and double-layer screening—oversized particles are crushed and recycled, qualified granules enter automatic packaging (20-50kg/bag), complying with GB/T 15063-2020.
Application Scope
Ideal for medium-scale fertilizer factories, agricultural input suppliers, and regional crop planting bases. Produces customized NPK compound fertilizer (15-15-15, 16-8-16, etc.) for grain, fruits, vegetables, and cash crops, meeting diverse soil and crop nutrient needs.
