The organic waste to fertilizer production line make use of organic waste as raw materials including straw, livestock manure, cake feeds, organic waste produced by processing of subsidiary agricultural products. Then these materials are made into organic fertilizer through microbial fermentation, deodorization and maturity.
Composting and fermentation of the materials. Any qualified organic
fertilizer must go through the process of composting and
fermentation.
Mixing and crushing. The crushing machines include semi-wet
material crusher, chain crusher, and hammer crusher. The mixing
machines include double shafts horizontal mixer, horizontal mixer,
single shaft continuous mixer, etc.
It is very important to choose what kind of granulating method in
the production of organic fertilizer. Nowadays, there are disk
granulation, rotary drum granulation, double roller extrusion
granulation and other methods in the industry.
After granulating, most of the materials have formed particles, but
the particle strength and water content doesn’t conforms to the
standard. So the drying process is essential.
After drying, the materials are transmitted to cooling machine
through belt. When the temperature is cooled to be normal, this
machine can further improve the particle strengths and reduce water
content.
After cooling, there are powdery material. This machine can screen
out the fine powders and large particles. Then the fine powdery are
engaged in the granulation again.
The finished products go to the coating process, making the
particles form a protective film and isolate from the outside air.
