1050°C Batch Processing Large Intermittent Lift-Tube Rotary Kiln

Product Name

GWDL-1050SSR-LD1430-6000 Large Intermittent Lift-Tube Rotary Kiln

Product Introduction

The GWDL-1050SSR-LD1430-6000 is a high-capacity intermittent rotary kiln featuring a liftable furnace tube, designed for precision calcination and sintering of bulk materials in ceramics, metallurgy, electronics, chemicals, refractories, advanced materials, and related industries.
Its adjustable tube inclination, variable rotation speed, and automated feeding/cooling functions enable efficient, repeatable processing in a fully programmable environment, with high thermal uniformity and optional atmosphere control.

Working Process

1. Feeding Stage
   • The stainless steel screw feeder automatically delivers material into the high-temperature furnace tube.
   • Feeding is PLC-controlled with a limit switch; once the set volume is reached, the system stops automatically.
2. Positioning & Heating
   • After feeding, the furnace tube angle is adjusted to the processing position.
   • Heating elements (SiC rods) are activated in top-and-bottom zones, with PID temperature control for each section.
   • Atmosphere gases (O₂, N₂, or Ar) can be introduced depending on process requirements.
3. Calcination / Sintering
   • The tube rotation speed (1–10 r/min) ensures even material exposure to heat.
   • Temperature precision of ±1°C guarantees uniform thermal treatment across the entire batch.
4. Cooling Stage
   • After the heating cycle, the tube is tilted to transfer material to the cooling section.
   • The double-layer shell and forced-air cooling system maintain an external temperature ≤45°C, protecting operators and equipment.
5. Discharge
   • Material is discharged once the target cooling temperature is reached.
   • The furnace tube is returned to its starting position for the next batch.

Design Features

• Liftable & Tiltable Tube – Adjustable inclination (0–35°) for optimal material movement during feeding, heating, and discharge.
• Fully Automated PLC Control – Siemens S7-1500 system enables recipe programming, PID self-tuning, auto heating/holding/cooling, and remote operation.
• High Thermal Uniformity – Multi-zone heating with ±1°C accuracy ensures consistent product quality.
• Flexible Atmosphere Control – Supports multiple process gases for specialized treatments.
• Durable High-Temp Materials – Furnace tube made from high-temperature stainless steel; insulation uses high-purity alumina fiber for efficiency and longevity.
• Efficient Cooling – Double-shell design with optimized airflow for safe operation.
• Continuous Batch Turnover – Rapid cycle changeover with minimal downtime.
• Unmanned Operation Ready – Programmable cycles and automatic alarms allow 24/7 operation without constant supervision.

Application Fields

• Ceramics – Structural and electronic ceramic sintering.
• Metallurgy – Heat treatment of metal powders and specialized alloys.
• Refractories – Firing of high-performance refractory components.
• Advanced Materials – Processing of composites and functional powders.
• Chemical Materials – Controlled-atmosphere thermal reactions.
