Description
1000℃ High-Temperature Energy-Saving Rotary Electric Kiln
The 1000℃ high-temperature energy-saving rotary electric kiln is an industrial-grade rotary kiln specifically designed for the continuous heat treatment of powders, granules, and lumpy materials. It is suitable for processes such as sintering, roasting, calcination, drying, activation, and heat treatment.
The equipment adopts an electrically heated rotary kiln structure, integrating an intelligent temperature control system, a variable frequency speed regulation system, an automatic screw feeder, an electric lifting mechanism, and a continuous cooling and discharging system. It can achieve continuous feeding, continuous heating, and continuous discharging, significantly improving production efficiency and reducing labor costs.The kiln body adopts a double-layer air-cooled structure, a high-purity alumina lightweight lining, and a four-layer energy-saving insulation design, featuring rapid heating, uniform temperature, high thermal efficiency, and low energy consumption.
Product Features
- Adjustable Tilt and Lifting, Wide Speed Range
The furnace tube features a split design with electric double-screw lifting. The tilt angle is adjustable from 1-15 degrees (lifting height controls the discharge speed). The speed is adjustable from 1-30 r/min. The flexible combination of tilt angle and speed allows for precise control of material residence time and throughput within the furnace tube, adapting to the calcination process requirements of different materials.
- Stainless Steel Screw Extrusion Feeding, Continuous and Stable Production
The feed inlet uses a stainless steel screw extrusion feeder with a diameter of 150mm and a length of 1800mm. This achieves continuous, uniform, and stable automatic feeding, suitable for large-scale industrial continuous production, improving production efficiency.
- Long-Distance Cooling Device, Discharge Temperature ≤50℃
The discharge port is designed with a 2300mm cooling device to ensure the discharge temperature remains below 50℃. The material is fully cooled before discharge, eliminating the need to wait for natural cooling before proceeding to the next process, significantly improving production efficiency.
- Four-layer insulation structure, energy saving of over 80%
The furnace lining uses vacuum-formed high-purity alumina lightweight material. The insulation material adopts a four-layer structure: alumina fiber cotton, alumina fiber board, alumina (polycrystalline) fiber board, and lightweight insulating bricks. This improves energy saving by over 80% compared to older electric furnaces. The furnace shell temperature remains below 45℃ during long-term, uninterrupted operation.
