The double roller granulator is a molding machine that can make the material into a specific shape. Particularly adapted to the granulation effect of ammonium bicarbonate, ammonium chloride, monoammonium phosphate, etc., the ball formation rate is 85%. The npk fertilizer double roll granulation production process is short, low energy consumption, and large output. The dry powder is directly granulated without subsequent drying process, which is more conducive to the connection and transformation of the existing production process. The double roller granulator has the following advantages:
1. Cyclic operation to achieve continuous production and high-yield finished products;
2. The strength of the particles can be adjusted, and the strength of the finished product can be controlled by adjusting the pressure of the roller;
3. The material is forcibly compressed and molded by mechanical pressure without any additives to ensure the purity of the product.
4. The extrusion fertilizer granulation machine is suitable for a variety of raw materials, and the particle strength can be adjusted freely according to different materials.
5. Compact structure, convenient maintenance, simple operation, short process flow, low energy consumption, high efficiency and low failure rate.
