Pan Granulator — Core Equipment for Standard Pelletizing

With the development of modern industrial production, higher requirements have been placed on the hardness and environmental‑friendliness of raw material processing. Our self‑developed pan granulator delivers an innovative and comprehensive solution for industrial production. Featuring unique design, reliable performance and eco‑friendly concept, it is an ideal option for granulating diverse materials such as bauxite, chemical raw materials, clay, sludge, fly ash and slag, and is widely applied in petrochemical, construction, fertilizer, refractory & thermal insulation material, proppant for petroleum fracturing and other key sectors.

1. Equipment Introduction

The pan granulator specializes in producing high‑quality spherical products ranging from 1 mm to 25 mm, including clay ceramsite, ceramsite sand, molecular sieve and refractory ceramsite. It features compact structure, flexible control and stable operation. It guarantees uniform particle size and high output of finished pellets, and fully embodies the modern industrial philosophy of environmental protection and efficient production.

2. Working Principle

The granulator operates on a sophisticated process flow: a variable‑frequency motor drives the inclined granulating pan through a reducer and intermediate coupling device. As the pan rotates, materials tumble inside while solution is sprayed evenly onto them. The solution contacts and adheres to material particles to form a thin liquid film. With continuous tumbling, the liquid film absorbs surrounding materials, so seed balls gradually grow and become denser. Mechanical force further improves the compactness and mechanical strength of green balls. Under precise process control, green balls meeting specifications are discharged through the discharge gate.

3. Performance Features

- **Eco‑friendly enclosed design**: The fully‑enclosed structure effectively suppresses dust pollution, improves working conditions and reduces material loss. It also delivers strong adaptability to various raw materials, high production efficiency and stable product quality.

- **Intelligent variable‑frequency drive**: Advanced variable‑frequency speed regulation reduces impact load during operation, ensures smooth running, extends motor service life and cuts energy consumption by over 30%.

- **Superior pelletizing performance**: High pelletizing rate and easy particle‑size adjustment. Produced ceramsite features uniform granularity and excellent strength. Full‑pan pelletizing greatly improves overall production efficiency.

- **Precision manufacturing technology**: Key frame components are integrally processed by large‑scale boring‑milling machines, ensuring high assembly accuracy and laying a solid hardware foundation for long‑term stable operation of the whole unit.
