The double roller extrusion granulator is dry granulation equipment that can quickly extrude and separate materials at room temperature and process them into oblate particles. Compared with other granulation equipment, no drying measures are required, which simplifies the granulation process. The return rate is very low, no need to add adhesives.
The double-roller extrusion granulator is widely used in the processing of fertilizer, NPK, urea, graphite, cat litter and other granules, with low investment and high production efficiency. Combined with other related equipment, it can form an automatic compound organic fertilizer granule production line.
It can be granulated at room temperature without any additives to complete the granulation work.
2. Low energy consumption
The advantage of dry granulation is that there is no need for drying and cooling after the granulation is completed. Save some energy consumption.
3. High adjustability
By replacing the roller grinding tools, the shape of the finished particles can be changed. Adjust the particle size of the roller extrusion to achieve the purpose of controlling the particle size.
4. Material can be customized: stainless steel
For materials with special properties, we recommend stainless steel double-roller extrusion granulators, which have better anti-corrosion properties.
Working Process of Double Roller Granulator
The material enters through the upper conical material opening, and the air between the material molecules is expelled by the action of pressure. Rely on the force between molecules to form a high-hardness ball cake, and then fall into the lower part of the sawtooth crumbs. The ball cake particles are separated by crushing; and then enter the screen, and the qualified particles flow out from the bottom outlet.
