1. Introduction to PQ45 Disc Granulator
The Huludao PQ45 Disc Granulator is designed for granulating mixed powders (including gold mine tailings, quartz stone, and phosphogypsum) into soil conditioners. Phosphogypsum, a major solid waste requiring treatment in China, is efficiently processed using this equipment. Through extensive testing and market validation, the disc granulator has proven to be the optimal solution for converting phosphogypsum powder into uniformly sized particles. Key features include uniform pellet size distribution, adjustable tilt angle, energy-efficient operation, and user-friendly maintenance.
2. Working Principle of PQ45 Disc Granulator
Powered by a main motor, the system drives a pulley and belt, which transfers motion to a reducer and pinion gear. The pinion meshes with a large gear fixed at the base of the rotating disc, enabling counter-directional operation. The disc, supported by a robust shaft and frame structure, works in tandem with a sprayer system. As materials enter the disc, the continuous rotation and spray action facilitate cohesive agglomeration into spherical granules. An integrated automatic wall-cleaning device prevents material buildup, enhancing equipment longevity. With continuous material input and motor operation, the system achieves high-volume production for uninterrupted workflows.
