The roller press granulation production line is a key complete set of equipment for organic fertilizer molding and processing. With its core advantages of “no drying required, low energy consumption, and uniform granules,” it has become the preferred solution for small and medium-sized organic fertilizer production. Through multi-stage collaborative operation, it transforms powdered organic fertilizer raw materials into regular granules, improving the convenience of product storage and transportation while ensuring stable nutrient release.
Breakdown of the production line’s core stages: First, raw material pretreatment: powdered organic fertilizer needs to be screened and mixed to remove impurities and ensure uniform composition, guaranteeing that moisture and nutrients meet standards, laying the foundation for granulation; the core granulation stage is completed by the fertilizer compaction machine. The pre-treated raw materials enter between two rollers, forming sheet-like material under high-pressure extrusion, and then uniform granules are obtained through crushing and screening; finally, through the finished product screening and return system, unqualified granules are returned to the crushing stage for secondary processing, maximizing raw material utilization.
Compared with other granulation processes, the roller press granulation production line has significant advantages. It requires no drying process, and the granules have high strength and regular shape, making them less prone to caking; it is adaptable to a wide range of raw materials, and can process various powdered raw materials such as livestock and poultry manure fermented fertilizer and straw organic fertilizer, with minimal nutrient loss.
Its application scenarios focus on small and medium-sized organic fertilizer production projects, especially suitable for production needs with strict energy consumption control and stable raw material supply. Whether it’s single-material granulation or multi-nutrient compound granulation, precise adaptation can be achieved by adjusting the roller press parameters.
