Various organic fertilizer machine manufacturers have developed a variety of granulators, such as roller extrusion granulators, stock granulators, disc granulators, new organic fertilizer granulators, new compound fertilizer granulators, flat die granulator, ring die granulator, etc, the model configuration is different, and the fertilizer granulator machine price varies. Today, let's talk about the roller extrusion granulator.
The roller extrusion granulator is widely used to granulate some waste materials, such as coal powder, carbon powder, coke powder, carbon black, mineral powder, dust removal ash, lime powder and other metal mineral powders, as well as industrial recycling dust materials, cast iron plants Dust, lead, zinc, aluminum dust, converter dust, filter dust, grinding dust, etc.
The twin-roll extrusion granulator has the following characteristics when producing granules:
1. Extrusion granulation does not require heating and humidifying materials, saving investment and energy, and is also suitable for granulation of heat-sensitive materials such as ammonium bicarbonate and some organic fertilizers.
2. There are no special requirements for the properties and particle size distribution of the raw materials, so the raw materials come from a wide range of sources.
3. The extrusion granulation process is short, easy to operate, easy to realize automatic production control and improve production efficiency.
4. The production is relatively flexible, and the product plan can be changed at any time, which is conducive to the small batch production of special fertilizers.
5. The particle size distribution of the product is uniform, and there will be no segregation or agglomeration.
6. There is no waste water and waste gas discharge during the production process, and does not pollute the environment
7. The shape of the extrusion granulation product is uniform and not round. Typically, if you need a more round product, add a fertilizer rounder, the process has high yield, processing, and pelleting comparable to disc pelletizing.
