Process of Compound Fertilizer Production Line

1.Automatic Batching Machine for Compound Fertilizer Production Line

Firstly, various materials are proportioned as per the formula by the 4-10 bins batching machine, which can complete materials batching automatically with high accuracy and high efficiency, thus the quality of the fertilizer is ensured. After batching, the materials are conveyed to the  mixer Machine.

2. Mixer Machine  of Compound Fertilizer Production Line

We adopt automatic and continuous mixer machine in this fertilizer production line. The cycloidal reducer drives the main shaft to rotate, and in turn drives the agitating spiral/screw. With the stirring of agitating screw and small shovels on them, the raw materials are fully mixed. After mixing, the materials are discharged from the outlet at the bottom. The inner side of the mixer can adopts polypropylene plate or stainless steel, which makes the materials not easily sticky, and abrasion resistance.

3. Double Roller Press Granulator / Double Roller Press Granulator for Compound Fertilizer Production Line

By the belt conveyor, the well mixed raw materials are conveyed to the pan feeder, which feeds the materials evenly into the four roller press granulator or roller compaction granulator under the feeder through the hopper. By the counter-rotating high pressure rollers, the materials are extruded into slices. The slices flow down to the crushing chamber under the press roller, where they are crushed by the crushing rollers and screened to get the required granular. The press rollers adopt new type metal which is resistant to corrosion, wear and impact.

4. Rotary Screening Machine for Compound Fertilizer Production Line

By the belt conveyor, the granules from the extrusion granulator are sent to the rotary screening machine, where unqualified granules pass through the screen aperature and discharge through the outlet at the bottom, then conveyed back to the pan feeder, while qualified granules flow out through the outlet at the lower end of the machine and conveyed to the finished products warehouse.

5. Automatic Packing Machine for Compound Fertilizer Production Line

Through the finished products warehouse, the qualified granules are weighed and packed by the automatic packing machine. The unit consists of automatic weighing and packing machine, conveying device, sealing device and feeder. It has the features of high weighing precision, stable operation, low power consumption, and small land occupancy.
