Quartz Sand Drying production line

Product Introduction:

The triple-pass rotary dryer is mainly used in industrial production for drying all granular, non-sticky, free-flowing materials such as quartz sand, yellow sand, clay, slag, coal, iron powder, etc. It is also suitable for drying bulk materials in compound fertilizer, phosphate fertilizer, and metallurgy industries.

The triple-pass rotary dryer is constructed by assembling three cylinders of different diameters together based on the single-pass rotary dryer. It generally adopts roller transmission, driven by 2-4 motors, and synchronized by a frequency converter. The cylinder is horizontally installed without inclination, making installation relatively simple and requiring a small footprint.

The middle and outer cylinders of the triple-pass rotary dryer are completely sealed, significantly improving thermal efficiency. During design and manufacturing, factors such as equipment material and the sturdiness of lifting plates are fully considered. With reasonable design and fine workmanship, the service life of the triple-pass rotary dryer is greatly extended.

Main Features:

1. The initial moisture content of materials is 15%, and the final moisture content is guaranteed to be below 0.5-1%, making it a reliable choice for cement plants, slag micropowder, and dry-mix mortar production lines.
2. The cylinder has self-insulation, with thermal efficiency as high as 80~85%. The outer cylinder wall temperature is below 60℃, significantly saving fuel compared to single-pass dryers.
3. The equipment's length is reduced by 60% compared to single-pass dryers, occupying less space and benefiting overall process layout.
4. The discharge temperature is <50℃, allowing direct entry into the storage silo.
