NPK manufacturing process
of simple equipment needs to use equipment: automatic batching, mixer, disc feeder, double roller fertilizer granulator machine, screening machine, packaging machine.
Equipment flow of NPK manufacturing process
Characteristics of NPK manufacturing process
- 1. The qualified raw materials are added into the mixer according to the proportion requirements and mixed evenly;
- 2. It is transported to the disc feeder to remove the iron substance in the material during the conveying process;
- 3. The materials in the disc feeder enter into the double roller fertilizer granulator machine evenly, and the materials are forced to pass between the two pressure rollers and are squeezed into thin plates. The thin plates are broken into fragments by the coarse crusher under the pressure roller, and the materials on the screen continue to be broken and screened;
- 4. The semi-finished products are transported to the screening machine of finished products; the fine particles after screening are directly returned to the disc feeder; the large particles are crushed by the pulverizer and then returned to the disc feeder,
- 5. After screening, the qualified products are transported to the automatic packing scale for weighing, packaging and warehousing.
The NPK manufacturing process adopts non drying normal temperature process, which is formed in one time. The equipment has the advantages of less investment, quick effect and good economic benefit. The complete set of equipment has the advantages of compact layout, scientific and reasonable technology, energy saving and consumption reduction, no three wastes elimination, stable production, reliable operation, convenient maintenance and wide adaptability of raw materials, which is suitable for compound fertilizer, medicine, chemical feed, coal, metallurgy, etc And it can produce various concentrations and kinds of compound fertilizers.
