DAP (diammonium phosphate) and MAP (monoammonium phosphate) are important compound fertilizers and are widely used to improve crop yield and quality. The double-roller extrusion granulator is an efficient dry granulation equipment specially used for producing single or compound fertilizers. Understanding its working principle can not only help you choose the right fertilizer granulation equipment but also improve your production efficiency and product quality.
DAP/MAP Granulator Process Flow
1. Raw material preparation:
o First, weigh and mix the raw materials of DAP or MAP (such as nitrogen source, phosphorus source and other additives) to ensure the accurate proportion of each component. (Single fertilizer can be directly granulated)
2. Feeding and conveying:
o The mixed material is fed into the roller extrusion granulator through a feeder. Ensure that the material maintains a constant material level when entering the granulator, thereby improving the stability and efficiency of production and realizing automated transportation production.
3. Extrusion granulation:
o In the roller extrusion granulator, the material is squeezed between two rollers rotating in opposite directions. The surface of the roller has a concave aperture, which is relatively flat and spherical. Through high-pressure extrusion, the material is compressed into uniform particles to ensure the strength and consistency of the particles.
4. Drying and cooling:
o The granulated particles are dried and cooled according to the moisture requirements to reduce the moisture content and ensure the storage stability of the product. The drying equipment is usually connected to the granulator to form an automated production line.
5. Screening and packaging:
o The dried particles are graded by screening equipment to ensure that the particle size meets the standard. The qualified particles are then automatically packaged and prepared for shipment to the market. The unqualified particles and dust are re-granulated.
