With the evolution of modern industrial production, there is an increasing demand for raw material processing that meets higher standards regarding material hardness and environmental sustainability. To address this, we developed the pan granulator, offering an innovative and comprehensive solution for industrial manufacturing. Distinguished by its unique design, efficient performance, and commitment to environmental protection, this equipment is the ideal choice for granulating a wide range of materials—including bauxite, chemical raw materials, clay, sludge, fly ash, slag, and fertilizers—and serves key sectors such as petrochemicals, construction, fertilizers, refractory and insulation materials, and petroleum fracturing proppants.

1. Introduction

The pan granulator is specialized in producing high-quality spherical products ranging from 1 to 25 mm, such as clay ceramsite, proppant, molecular sieves, and refractory ceramsite. With a compact design, flexible control, and stable operation, it not only ensures uniform particle size and high output, but also fully embodies the modern industrial concepts of environmental protection and efficient production.

2. Working Principle 

The core mechanism of this granulator lies in its sophisticated process: a variable-frequency motor drives the granulation pan to rotate at a specific angle via a speed reducer and an intermediate transmission assembly—a design that is both scientifically sound and highly effective. During rotation, the material rolls within the pan while being subjected to a uniform spray of solution; the solution rapidly contacts and adheres to the material particles, forming a thin liquid film. As the rolling continues, this film continuously picks up surrounding material, causing the granules to gradually grow in size and increase in density. Throughout this process, the application of mechanical force further enhances the granules' compactness and mechanical strength; finally, through precise control, the process yields specification-compliant raw granules that are discharged via the discharge gate.
