Product Features Rotary Kiln
- Multi-section structure, integrated process flow
This equipment is a large-scale multi-section rotary kiln, approximately 40 meters in length, consisting of a feeding section, a drying furnace (5 zones), a calcining furnace (5 zones), a tail gas purification furnace (4 zones), and a cooling section. It integrates drying, calcination, tail gas purification, et refroidissement, achieving continuous and automated production of material heat treatment processes.
- Large-diameter, long furnace tubes, outstanding processing capacity
The drying and calcining furnaces have furnace tubes with a diameter of 1030mm and a length of 6000mm. The cooling section also has a diameter of 1030mm and a length of 6000mm. This allows for large-scale, continuous industrial production with a large single-batch processing capacity.
- Independent zone heating, flexible process
The drying furnace has 5 heating systems, the calcining furnace has 5 heating systems, and the tail gas purification furnace has 4 heating systems. Each heating zone can be independently controlled. The control panel has a manual heating start knob, and the touchscreen allows engineers to manually operate each heating zone and flexibly adjust process parameters.
- Fully Automatic PLC Control, Remote Monitoring
Utilizing an S7-1500 series central CPU controller, the system implements sequential, conditional, timing, and counting control of the process electrical control equipment, PID adjustment, 485 communication, and Profinet interface control functions, as well as automatic accumulation and data processing of flow and energy parameters. It supports network topology and remote monitoring.
- Exhaust Gas Purification System, Environmentally Compliant
The exhaust gas purification furnace is equipped with four heating zones and four temperature control points, providing high-temperature purification of waste gas generated during drying and calcination, effectively removing harmful substances and meeting environmental emission requirements.
- Cooling and Waste Heat Recovery, Energy Efficient
The cooling section is equipped with two temperature measurement points: one at the waste heat recovery inlet and one at the outlet, as well as a water pressure gauge with electrical contacts. Except for the waste heat recovery motor, all other motors in the cooling section—feed motor, furnace tube rotary motor (two 4KW frequency converters), waste heat recovery motor (4KW frequency converter), and spray motor (2.2KW)—use direct start control, achieving efficient cooling and waste heat recovery.

Application Areas Rotary Kiln
- Continuous Production of Battery Materials: Suitable for the continuous production of precursors for lithium-ion battery cathode materials (lithium iron phosphate, ternary materials, etc.), including drying and calcination. A 40-meter-long furnace enables a continuous process from feed to finished product.
- Catalyst Calcination: Suitable for the continuous drying, calcination, and activation of catalyst supports, molecular sieves, and other materials. Multi-stage temperature control meets complex temperature profile requirements, and a tail gas purification system ensures environmental compliance.
- Metal Oxide Reduction: Suitable for the continuous reduction of metal oxides such as iron oxide, copper oxide, and tungsten oxide to prepare high-purity metal powders.
- Chemical Raw Material Calcination and Decomposition: Suitable for the continuous calcination and decomposition of chemical raw materials such as carbonates and hydroxides. High capacity and efficiency, suitable for large-scale industrial production.
- Mineral Roasting: Suitable for mineral pretreatment processes such as spodumene roasting, iron ore magnetization roasting, and rare earth mineral decomposition. Multi-point temperature control and adjustable atmosphere meet the roasting requirements of different minerals.
- Solid waste pyrolysis treatment: Suitable for the pyrolysis, incineration, and harmless treatment of industrial solid waste, sludge, and hazardous waste. The large-diameter furnace tubes and long furnace body design are suitable for large-scale continuous processing.
- Waste heat recovery and energy-saving production: The waste heat recovery system in the cooling section can recover and utilize the heat from high-temperature materials, preheating incoming materials or using it for other processes, significantly reducing energy consumption.
