Non drying granulation technology and characteristics of roller press granulator

2020-08-24

The non drying extrusion granulation process of double roller press granulator is widely used in powder particle processing. The characteristic of this process is that the particles can be directly treated without humidification or heating. It can be used as fertilizer production machine to process organic fertilizer and inorganic fertilizer granules, as well as feed granules.

Extrusion granulation process

Most fertilizers need to be dried and cooled after granulation process, such as rotary drum granulator, organic fertilizer granulator and disc granulator. Extrusion granulation process is short, easy to operate, easy to realize automatic production control and improve production efficiency. There are no special requirements for the properties and particle size distribution of raw materials, so the sources of raw materials are relatively wide.
Non drying granulation technology of roller press granulator

The double roller granulator has the following characteristics in the production of granules:
1. Extrusion granulation does not need heating and humidifying materials, saving investment and energy. It is also suitable for granulation of heat sensitive materials such as ammonium bicarbonate and some organic fertilizers.

2. There is no waste water and waste gas emission in the production process, which does not pollute the environment.

3. Extrusion granulation process is short, easy to operate, easy to realize production automation control and improve production efficiency. The double roll extrusion granulator is suitable for the processing technology of small-scale fertilizer production machine.

4. There are no special requirements on the properties and particle size distribution of the raw materials, so the raw materials have a wide range of sources.

5. Fertilizer production is relatively flexible, and the raw material formula can be changed at any time, which is conducive to the small batch production of special fertilizer.

6. The particle size distribution of the product is uniform, without segregation or agglomeration.

7. The extrusion granulation product has uniform shape, oval shape and non-circular shape. Generally, if you need a rounder pellet, you need to add a rounding machine to the fertilizer production line to further reshape the pellet.
