NPK Fertilizer Batching and Mixing System – Automatic Raw Material Proportioning for Compound Fertilizer

Stable nutrient proportion is the core quality index of qualified NPK compound fertilizer. The NPK fertilizer batching and mixing system undertakes raw material weighing, proportioning and homogenizing mixing, which is the front-end core unit of the whole NPK fertilizer production process. Unstable batching and uneven mixing directly lead to inconsistent N-P-K content in finished fertilizer and fail agricultural nutrient standards. Our automatic batching and mixing system is widely matched with NPK granulation lines for fertilizer factories around the world.

Why Automatic Batching & Mixing Matters for NPK Fertilizer Production

Manual weighing brings large proportion errors and low production efficiency. Automatic batching system precisely controls the weight of urea, ammonium chloride, potassium chloride, fillers and trace elements. After accurate batching, the mixer blends all powder materials uniformly. Stable mixing ensures every fertilizer granule has consistent nitrogen, phosphorus and potassium nutrients. This system lays the foundation for stable finished fertilizer quality and reduces product rejection rate.

Main Components of NPK Batching and Mixing System

Multi-hopper Automatic Batching Unit

Multiple storage hoppers store different fertilizer raw materials. Load cell sensors under each bin realize dynamic weighing. The system automatically feeds materials according to preset NPK formula ratio. We support 3 to 8 bins design to fit different raw material types.

Horizontal Powder Mixer Machine

Quantified raw materials are transported into the horizontal mixer. Internal ribbon blades perform fast and homogeneous mixing. Short mixing cycle keeps high production capacity while ensuring uniform powder distribution. The mixer body is easy to clean and resistant to chemical corrosion.

Conveying and PLC Control Module

Screw conveyors transport raw materials between batching bin and mixer without powder leakage. The PLC touch screen stores multiple NPK formulas. Operators can switch formulas quickly for different fertilizer products. Production data can be recorded for quality traceability.
