1-20t/H Capacity Organic Fertilizer Production Line

Technical Process for Granule Organic Fertilizer Plant
The entire production line is mainly used to process materials (cow dung, sheep dung, pig dung, chicken dung, sludge, rice straw, corn straw) and other animal manure organic waste after fermentation and decomposing, which contains about 30%-35% moisture content. After crushing and sieving, the binder (bentonite, humic acid) and other ingredients that need to be proportioned are measured in the batching mixing system according to the proportioning requirements. (Adding functional bacteria can produce biological organic fertilizer, adding nitrogen and phosphorus , Potassium (the total nutrient content is less than 15%) can produce organic and inorganic fertilizer) dosing, mixing, the fully mixed material is uniformly and continuously fed into the granulator by the belt conveyor, and then rounded into spherical particles by the polishing and shaping machine. After drying at low temperature and high air volume by dryer (≤65ºC), it is cooled and sieved. The finished particles are conveyed to the finished product silo by belt, and are measured and packed into storage by the computerized quantitative packaging system.

1.Materials dewater

Liquid manure of animals content high moisture,which should be dewater then enter to next process.

2.Fermentation

The crushed stalks and animal manure need to be fermentation to kill a large number of animal fecal bacteria,parasite,etc.When the materials is fermentation,it need turning,so fermentation can be more thorough.

3.Materials crushing

The animal manure in blocks after fermentation,it should be crushed through the pulverizer,which become relatively fine power is suitable for granulation.

4.Mixing

The mixed material should be mixed completely,then get into granulator.

5.Granulation

There are several types fertilizer granulator,if we produce organic fertilizer,it is better to use disc fertilizer granulator.

6.Drying

After granulating,the moisture of fertilizer is bit high,it is not suitable for long-term storage so we need send make drying process.

7.Cooling

The cooling machine is used to cool the hot fertilizer.

8.Screening

There are some non-uniform particles,after sieved screening machine,the small particle diameter may be screened down for twice processing.

9.Coating

Under the particle surface is not uniform,sleek case,we need to be coat the surface of fertilizer granules.

10.Packaging

After package,the fertilizer can be sold.

Raw material of Granule Organic Fertilizer Plant

1. Agricultural waste: straw, dregs of beans, cotton dregs, rice bran, etc.
2. Animal and Poultry manure: mixture of poultry litter and animal waste, such as the wastes of slaughterhouse, fish market, urine and dung of cattle,pigs, sheep, chicken, ducks, geese, goat, etc.
3. Industrial waste: wine lees, vinegar residue, manioc waste, sugar scum, furfural residue, etc.
4. Home scrap: food waste, the roots and leaves of vegetables, etc.
5. Sludge: the sludge of the river, sewer, etc.
