What is a double roller extrusion machine?

Double Roller Extrusion Machine: This is the central piece of equipment in the production line. It consists of two counter-rotating rollers with specific patterns on their surfaces. The raw materials, typically powdered or granular materials containing nutrients like nitrogen, phosphorus, and potassium, are fed into the gap between the rollers. As the rollers rotate, the material is compacted and forced through the small spaces between the rollers, resulting in the formation of granules.

What is the process flow of a roller extrusion fertilizer production line?

Crushing and Mixing Equipment: Before the raw materials are fed into the extrusion machine, they may need to undergo crushing and mixing processes to ensure uniformity and proper composition of nutrients. This equipment may include crushers, mixers, and other pre-processing machinery.
Screening Machine: Once the granules are formed through extrusion, they may need to be screened to remove any oversized or undersized particles, ensuring uniformity in size.
Coating and Packaging: After screening, the granules may be coated with additional substances such as anti-caking agents or micronutrients to enhance their properties. Finally, the finished fertilizer granules are packaged into bags or other containers for distribution and sale.
