Introduction to the production of organic fertilizer from livestock manure by
rotary drum granulation process:
The processed livestock manure (cow manure, sheep manure, chicken manure, pig manure, duck manure, etc.) is directly transported to the raw material silo (or raw material mixer).
The material is fed with saturated steam (or water) to the drum pelletizer, and the material is formed into a rolling bed by the friction generated by the rotation of the drum pelletizer, and the extrusion pressure generated by the rolling makes the material containing liquid phase agglomerate into small particles, which become the core and adhere to the surrounding powder to form qualified particles.
Conveyed to the organic fertilizer dryer, with the heat from the hot air furnace heat exchange.
Conveyed to the thermal screening in the sorting particles, fine particles directly back to the drum granulator, as the core continue to participate in the adhesion of particles into balls.
After screening, the semi-finished pellets are transported to the organic fertilizer cooler, where the fertilizer is cooled by natural or forced cold air.
The granules are crushed by the pulverizer and then returned to the drum granulator to continue to participate in pellet formation.
After screening, the qualified product is conveyed to the wrapping machine for film coating.
Conveyed to automatic packaging scale for weighing, packaging and storage.
Drying, cooling and workshop dust are treated by cyclone dust collector, labyrinth dust chamber and wet scrubbing in three stages and then exhausted to the standard.
