Organic and NPK fertilizer making machines

The rotary drum churning granulator production line

The complete set of rotary drum churning granulator production line has the advantage of short process of production, simple structure, low investment and easy operation. It is more suitable for the organic fertilizer making from breeding plants, pig manure, cow manure, chicken manure, crop straw and so on.
The process flow of the complete set of rotary drum churning granulator production line:

Organic Fertilizer Pin Granulator1. The treated cow dung is transported directly to the silo of raw material (or raw material mixer)
2. The raw materials is sent to rotary drum churning granular. The granulation rate of the rotary drum churning granulator is as high as 80-90%. And it is suitable for a variety of formulations. The compressive strength of organic fertilizer is higher than that made by disc granulator and rotary drum granulator. The rate of large balls is less than 15%. And the uniformity and size of pellets can be adjusted according to requirements of users. This granulator is suitable for direct granulation of organic fertilizer after fermentation, which saves the process of drying and greatly reduces the cost of manufacturing.
3. The pellets are transported to the rotary drum dryer for heat exchange with the heat from the hot blast furnace.
4. The rotary drum cooling machine is to cool the pellets through natural or strong cooling air.
5. After the rotary screening machine, the large pelletes are crushed by the crusher and then returned to participate in the formation of ball.
6. The qualified products after screening are transported to the coating machine for coating.
7. Then they can be transported to automatic packaging scale for weighing, packaging and storage.
