The disc granulation production line is an efficient fertilizer production equipment that realizes raw material agglomeration into granules through an inclined rotating disc, widely used in the manufacturing of granular fertilizers such as organic fertilizers, compound fertilizers, and bio-organic fertilizers. The production line mainly consists of a disc granulator, raw material mixer, belt conveyor, dryer, cooler, screening machine, etc. It can form uniform granules from powdery or wet raw materials by adding an appropriate amount of water or binder under the rotation of the disc. With simple process and convenient operation, it is especially suitable for small and medium-sized fertilizer production enterprises, capable of meeting the demand for granules of different particle sizes (2-6mm). The produced granular fertilizers are applicable to farmland, gardens, fruit and vegetable planting and other scenarios, featuring stable fertilizer efficiency and convenient application.
