1-3T/H Liquid Fertilizer Production Line: Cold & Hot Mix Dual Process Integrated Liquid Fertilizer Manufacturing Equipment
Core Market Pain Points Solved by Complete Liquid NPK Fertilizer Production Line
Single Mix Technology Limits Product Diversification of Ordinary Liquid Fertilizer Equipment
The low-cost liquid fertilizer equipment on the market only supports the simple cold mixing process and cannot complete the thermal neutralization and reaction processing.
The factory can only produce low-concentration clear liquid fertilizer, and it is difficult to launch high-value-added suspended liquid fertilizer.
The whole set of liquid NPK fertilizer production line is equipped with hot and cold double supporting reactors.
Fertilizer manufacturers can freely switch between the two production processes, and one production line can simultaneously produce clear liquid and suspended liquid fertilizers.
Discrete Tanks Lead Unstable Fertilizer Formulation & Easy Crystallization
The split-type mixing tank does not have an integrated automatic feeding system, relying on manual weighing and feeding.
The order of raw materials is wrong, and the mixing speed is unbalanced, which makes it easy to produce crystallization and sedimentation problems during storage.
The liquid NPK fertilizer production line is equipped with a PLC automatic feeding system, strictly regulates the order of various raw materials, and avoids fertilizer crystallization and sedimentation from the root.
Simple Filtration Structure Reduces Finished Fertilizer Shelf Life
Low-cost equipment is only equipped with a single-layer filter, which cannot block fine undissolved impurities.
Small impurities are easy to block drip irrigation pipes, and at the same time greatly shorten the shelf life of liquid fertilizer.
The liquid NPK fertilizer production line is equipped with a double-stage precision filtration unit.
With the adjustable 80-10 mesh filter, the residue can be completely filtered out, effectively extending the storage time of fertilizer.
Manual Filling Reduces Whole Line Automation & Raises Labor Cost
Small and scattered liquid storage tanks require multiple workers to complete the entire process of measurement and filling.
The manual weighing of nutrients has a large error, and the weight of the finished product is uneven.
The fully automatic liquid NPK fertilizer production line integrates an integrated filling unit.
Only one inspection person is needed for the entire production line, and the labor cost in the workshop is reduced by more than 70%.

Standard Complete Manufacturing Flow of Liquid NPK Fertilizer Production Line
Step 1 Raw Material Sorting & Preprocessing
Collect plant residues, organic waste, and solid nitrogen, phosphorus, and potassium production raw materials.
Pre-crush large lumps of impurities and sieve out foreign impurities.
Processing qualified raw materials is sent to the unloading tank as a reserve through the lifting equipment.
Step 2 Raw Material Feeding & Reaction Mixing
The manufacturer can choose two production routes independently:
Cold mixing route: raw materials are added to the mixing tank in accordance with the specified order to be dissolved and mixed at room temperature.
Hot mixing route: Phosphoric acid and ammonia are fed into the reactor, and the neutralization reaction is completed by heating.
Step 3 Auxiliary Additive Homogenization
The basic liquid after preliminary dispersion is sent to the auxiliary dispersion tank.
Add humic acid, chelated trace elements, and stabilizers according to the product formula.
High-speed stirring evenly disperses various additives in the liquid.
Step 4 Dual-Stage Impurity Filtration
The mixed finished liquid passes through two processes, coarse filtration and fine filtration, in sequence.
Coarse filtration intercepts large particle residues, and fine filtration captures fine insoluble substances.
The filtered fertilizer will not clog drip irrigation and sprinkler irrigation equipment when used.
Step 5 Finished Liquid Constant Temperature Storage
The filtered and qualified liquid NPK fertilizer is transported to the finished product storage tank.
The storage tank temperature-stabilizing system prevents winter low-temperature crystallization.
