Промышленная вращающаяся печь

Industrial Rotary Kiln are used for continuous heat treatment of powdered or granular materials. As the kiln rotates, the material is constantly tumbled during the heating process, resulting in more uniform heating and a more stable reaction.

This equipment is suitable for medium to large-scale production environments and can complete calcination, drying, reduction, and other heat treatment processes under high-temperature conditions. Different temperature zones and atmosphere control systems can be configured according to process requirements.

Особенности продукта (Промышленная вращающаяся печь)

1. Continuous Dynamic Heat Treatment, Large Processing Capacity

This industrial rotary kiln employs a rotating cylinder structure. Materials continuously tumble and move within the cylinder, achieving large-scale dynamic heat treatment with continuous feeding and discharging.

2. Uniform Material Heating Due to Cylinder Rotation

The cylinder is driven by a motor with stepless speed regulation. The material is constantly scooped up and tumbled inside the cylinder, making full contact with the hot airflow and heating evenly. This prevents localized overheating or uneven sintering, thus ensuring product quality.

3. Adjustable Tilting Angle, Controllable Residence Time

The cylinder's tilt angle can be adjusted according to material characteristics and process requirements. Combined with speed control, the residence time of materials within the furnace can be precisely controlled. A larger tilt angle and faster speed result in faster material flow and shorter residence time.

4. Multi-zone independent temperature control, precise temperature curves

Multiple independent heating zones (preheating zone, high-temperature zone, cooling zone) are set along the length of the cylinder. Each zone can be individually temperature-set, achieving precise control of heating, проведение, and cooling curves to meet complex process requirements.

5. Multiple cylinder material options

The interior of the furnace tube can be lined with heat-resistant steel, stainless steel, or ceramic, depending on the characteristics of the material and the operating temperature. It is resistant to high temperatures, corrosion, and wear.

Области применения (Промышленная вращающаяся печь)

• Battery Materials: Suitable for continuous sintering of positive electrode materials for lithium iron phosphate, ternary materials, lithium cobalt oxide, lithium manganese oxide, и т. д., as well as carbonization and graphitization of negative electrode materials. Nitrogen or argon gas can be introduced for protection to prevent material oxidation.
• Catalysts and Supports: This is particularly suitable for the continuous calcination, activation, and regeneration of materials such as catalysts, molecular sieves, and activated carbon. The dynamic rotation method ensures that the materials are heated very evenly, guaranteeing both catalytic activity and product consistency.
• Metal Oxide Reduction: Suitable for the reduction treatment of metal oxide powders such as iron oxide, copper oxide, tungsten oxide, molybdenum oxide, и т. д., to prepare high-purity metal powders. Hydrogen or carbon monoxide reducing atmosphere can be introduced to achieve efficient reduction.
• Chemical Raw Material Calcination: Suitable for continuous calcination and decomposition of chemical raw materials such as calcium carbonate, aluminum hydroxide, barium sulfate, titanium dioxide, и т. д., to remove water of crystallization or carbon dioxide and obtain high-purity products.
• Mineral Processing: Suitable for pretreatment processes such as roasting, oxidation, and reduction of minerals, including spodumene roasting, iron ore magnetization roasting, and rare earth mineral decomposition.
• Solid Waste Treatment: Suitable for the pyrolysis, incineration, and harmless treatment of industrial solid waste, sludge, and hazardous waste. Dynamic rotation ensures full contact between materials and hot air, resulting in thorough combustion and good volume reduction.
• Порошковая металлургия: Suitable for the reduction and pre-calcination of metal powders and alloy powders. A protective atmosphere can be introduced to prevent oxidation and improve powder activity and sintering performance.
• Building Materials Industry: Suitable for continuous calcination of building material raw materials such as ceramsite, lightweight aggregate, cement clinker, lime, and gypsum.
• Новый материал R&D and Pilot Production: Suitable for pilot-scale R&D and mass production of high-end materials such as special ceramic powders, nanomaterials, и композиционные материалы, providing process verification for industrial scale-up.

Часто задаваемые вопросы (Часто задаваемые вопросы)

1. What is the difference between an industrial rotary kiln and a laboratory rotary kiln?

Industrial rotary kilns are large in size, have high output, and can operate continuously for 24 hours; laboratory rotary kilns are used for small-batch research and development.

2. What is the kiln diameter?

From 0.5 meters to over 3 meters, and the length from a few meters to tens of meters, настраивается в зависимости от объема производства.

3. What is the maximum temperature?

500℃-1600℃, depending on the material's process requirements.

4. Why is the kiln tilted?

The tilt allows the material to automatically move from the high end to the low end during rotation, achieving continuous feeding and discharging.

5. Can it handle corrosive or sticky materials?

Specific designs can be adopted.
