Compound fertilizer roller extrusion granulating process and disadvantages brief introduction:

1. Making qualified raw material according to ratio requirements add to high efficiency mixer uniform mixing;
2. Conveying to disc feeder, during conveying process, remove all the iron property material;
3. Material discharged from disc feeder uniform feeding to roller extrusion granulator, through two roller press to form.
4. Semi-products conveying to final products screen, after screened, finer granule directly return to disc feeder, too big size granule through crusher crush then return to disc feeder.
5. After screened, qualified products conveying to full auto-packing machine to weigh, pack and storage.
Using roller granulating plant process produce compound fertilizer with the following disadvantages:
1. Roller extrusion granulating production no need heat and humidificate to material, not only save investment, but also save energy and can also suit for material content thermosensitive property, such as ammonium bicarbonate and some other organic fertilizer material granulating.
2. During the production process without waste water or waste gas efflux and won't pollute environment.
3. Roller extrusion fertilizer granulating with short process, easy to operate, convenient for realize production auto-control, improve the production efficiency.
4. For raw material property and granularity distribution without special requirements, so suit for many raw materials.
5. Flexible production, can change products solution, benefit for small batching produce special fertilizer.
6. Uniform products granularity distribution, won't agglomeration.
7. Roller granulating machine output products outlooks isn't smooth as drum granulator and slurry granulation and other traditional method produced granule.
