What are the differences among the three types of extrusion fertilizer granulator
1. Double roller granulator
The double roller granulator is suitable for making soluble or non viscous particles, especially for chemical fertilizer particles. It is not suitable for granulating organic fertilizer with sticky rice husk and chicken manure with certain water content. It is easy to plug the die hole. It is necessary to clean the mold hole regularly, resulting in the consequence of not working continuously. It is suitable for granulation of compound fertilizer, medicine, chemical industry, feed and other raw materials with high granulation rate.
2. Flat die extrusion granulator
The fertilizer granulation machine is suitable for granulation of crude fermented organic fertilizer. It is mainly suitable for coarse fiber granulation, such as sawdust, rice husk, cotton stalk, cottonseed skin, weeds and other crop straws, domestic garbage, waste plastics and factory wastes, granulation, briquetting and rod making of materials with low adhesion rate and difficult to form, and low temperature granulation of biological bacterial fertilizer, organic fertilizer and compound fertilizer. Production capacity: 1.0 ~ 4.0 T / h; pelletizing rate: more than 95%, less return material; power: 22 ~ 90 kW.
Flat die organic fertilizer granulation machine consumes a lot of energy and has a higher extrusion strength. When iron and steel waste is mixed with organic fertilizer raw materials, it is easy to damage the granulation template and sometimes block the holes of the granulation template. Additional equipment care and replacement of consumables are required. At the end of each shift, it is best to add anti-clogging materials to pelletize to prepare for the next shift.
3. Ring die extrusion granulator
Ring die granulator is similar to flat mold extrusion granulator, which can be widely used in small and medium-sized aquaculture, food and feed processing, livestock farms, poultry farms and individual farmers.
