Product Overview

The Triple Cylinder Rotary Dryer is a high-efficiency industrial drying solution designed for sand, minerals, and granular materials. It consists of three concentric cylinders (inner, middle, and outer) that work together to maximize heat exchange and reduce energy consumption.

Developed by Tongding’s R&D team with 26 invention patents, this dryer is widely used in building materials, metallurgy, mining, petrochemical, and foundry industries for drying materials such as mortar sand, fracturing sand, foundry sand, plate sand, glass sand, and descaling sand.

Compared with traditional single-drum dryers, the triple-pass design delivers 40% higher thermal efficiency, requires 60% less floor space, and achieves final moisture content below 0.5%.

Patent-Protected Design Innovations

  • Multi-bend sand lifting plates: Create a waterfall-like material curtain for maximum heat exchange (Patent ZL 2017 1 1292672.4, ZL 2017 2 1697400.8)
  • Serrated sand lifting plates: Increase contact area for secondary drying (Patent ZL 2017 1 1292674.3, ZL 2017 2 1697127.9)
  • Large double-layer kiln head: Anti-backflow design prevents material blockage and heat loss (Patent ZL 2018 1 1513638.X, ZL 2018 2 2074629.7)
  • Forged running belt: Dense structure, no casting defects, longer service life
  • Heavy hammer discharge valve: Reduces air loss and increases output (Patent ZL 2018 1 1513639.4)
  • Combined sand lifting plate inner cylinder: Optimized for uniform drying (Patent ZL 2017 1 1292967.1, ZL 2017 2 1697016.8)
  • Anti-clogging self-cleaning sand flow channel: Prevents material adhesion and ensures consistent flow (Patent ZL 2017 1 1292651.2, ZL 2017 2 1697357.5)

Flexible Fuel Options

The drying system supports multiple heat sources. We recommend the most cost-effective burner based on your local fuel availability:

  • Diesel / Natural Gas / LPG – Clean and efficient, ideal for environmental regulations
  • Biomass – Suitable for wood chips, building templates, agricultural residues
  • Heavy Oil – Cost-effective for large-scale operations
  • Coal – Where permitted, with proper emission control
