The process flow of the double roller granulator
is short, and the auxiliary equipment and personnel are few. The increase of bulk density is more significant than that of granulation. The size of particle strength can be adjusted by hydraulic pressure. The closed cycle operation of the system realizes continuous production.
Dry double roller granulator mainly relies on external pressure to force the material to pass through the gap between two relatively rotating rollers and compress into pieces. In the rolling process, the actual density of the material can be increased by 1.5-3 times, so as to achieve certain strength requirements.
The main transmission parts of the double roller granulator are made of high-quality alloy materials. Made of stainless steel and other surface alloys, the wear resistance, corrosion resistance, high temperature resistance and pressure resistance of the machine are greatly improved, so that the fertilizer granulation machine
has a long service life.
Performance characteristics of the double roller granulator:
1. The material is compressed and molded by mechanical pressure without any additives. The purity of the product is guaranteed. The dry powder is granulated directly without subsequent drying process, which is more conducive to the convergence and transformation of the existing production process.
2. The increase of bulk density is more significant than other granulation methods. It is especially suitable for the occasion of increasing the stacking proportion of products. It can adapt to a wide range of raw materials, and the particle strength can be adjusted freely according to different materials.
3. Compact structure, convenient maintenance, simple operation, short process, low energy consumption, high efficiency, low failure rate.
