Spray Granulation Dryer for Fertilizer

Spray granulation dryer for fertilizer

Spray granulation dryer is an important component of fertilizer making equipments.It is suitable for producing the ammonium phosphate and the surfuric NPK compound fertilizers.The process of granulation,dry,grade and inner recyle are finished in a body,so its function is powerful.
Main technical parameters

China organic waste to fertilizer machine
Organic fertilizer is rich in a lot of beneficial substances, including: a variety of organic acids, peptides and rich in nitrogen, phosphorus and potassium. Nutritional elements. It not only provides comprehensive nutrition for crops, but also has long fertilizer effect. It can increase and update soil organic matter, promote microbial reproduction, improve soil physical and chemical properties and biological activity, and is the main nutrient for green food production. In addition ,it is easy to get in the nature and available in many waste.

The source of the organic fertilizer raw materials:
1.Agricultural waste,such as straw, soybean meal, cotton aphid and so on.

2. Livestock manure,such as chicken manure, cattle and sheep horse dung, rabbit dung;
3.Industrial waste,such as distiller's grains, vinegar grains, cassava residue, sugar residue, furfural residue, etc.;
4.Livestock garbage,such as kitchen waste, etc.;
5.City sludge,for example, river silt, sewer sludge, etc. 

Production process of organic fertilizer 

1.Fermentation:All kinds of organic raw materials  will be put into the fermentation tank for fermentation;

2.Granulation:the raw materials will be fed into the granulator to make into fresh granules.

3.Drying:After granulation, though granules has been formed, but right now its moisture is too high, so they will be conveyed to the rotary dryer for drying.

4.Cooling:The temperature of the granules coming out of the dryer is quite high, then the granules will be send to the rotary cooler for cooling to further increase the granules strength and reduce the moisture.

5.Sieving:After cooling, the granules will be pass the sieve to separate coarse granules and fine powder, final product will be achieved. The big granules and the fine powder will go through the  grinder and recycle to the granulator, which will make them participate in the granulation process again .

6. The granules after sieving will be sent to automatic packing machine and then storage in bulk. 

Remark: This granulation process can be used for producing various kinds of fertilizer, includes organic fertilizer, NPK fertilizer, humic acid fertilizer and controlled release fertilizer etc, it can be used for hundreds of formulas of fertilizer .This production line is a multi-function production line.
