Working Principle of Dry Double Roller Granulator


Roller granulator is a dry granulation equipment developed by our factory, which absorbs advanced powder granulation technology from abroad, and improves it on the basis of foreign technology. Its structure is more reasonable and compact, and its particle density is large. It does not need further processing. It reduces the technological process, not only reduces the cost of granulation, but also reduces dust pollution and improves the working environment of workers.
Granulation principle
Various dry powder materials are added from the top of the equipment. Under the action of the extrusion force on the roll, the material is plastic deformed and compressed into an ellipse. Elliptical material is screened to obtain suitable granular products.
Working Principle of Dry Double Roller Granulator
Characteristics of Dry Roller Granulator
1. Material is formed by forced compression under mechanical pressure without adding any wetting agent, which does not destroy the chemical properties of the material, reduces the effective content of the product, and ensures the purity of the product.
2. The process flow is short, the energy consumption is low, the output is large, the production process is automated, and the cycle operation is suitable for large-scale continuous production.
3. The direct granulation of dry powder does not need the follow-up drying process, which is more conducive to the connection and transformation of the existing production process.
4. Particle strength is high, and the increase of accumulation ratio is more significant than other granulation methods. Particularly suitable for the occasion of increasing the proportion of product accumulation, the particle strength can be adjusted, and the strength of finished products can be controlled by adjusting the pressure of rolls.
5. The whole process is completely closed without any additives. Dry powder is directly granulated. The product has high purity and no pollution to the environment.
6. The whole set of equipment is made of stainless steel or titanium alloy steel, which has good anti-corrosion performance.
