Lime Rotary Kiln
Lime rotary kiln has many advantages in the calcination of lime. It is also known as the lime kiln, and is a professional, strong calcining equipment. Its main advantages include great production capacity, no noise, low energy consumption, and stable product quality.
LIMING Machinery Co., Ltd. manufactures this equipment with over 30 years of industry experience, ensuring reliable performance, high efficiency, and long service life. Our equipment is widely used in cement plants, mining operations, and mineral processing facilities worldwide.
Applications
Mainly for lime production line and calcined dolomite production.
Our equipment is designed to handle various materials and operating conditions, providing consistent performance and output quality. The robust construction and advanced control systems ensure stable operation even under the most demanding industrial environments.
Performance Advantages
New Technology
Main drive system adopts AC frequency conversion speed regulation technology. More energy-saving, wide speed regulation range, high efficiency, precise speed control, and stable operation.
Installation Accuracy
Supporting device base welding eliminated of stress through vibration aging treatment, guaranteeing machining accuracy and significantly improving installation reliability.
Smooth Operation
Overall structure optimization for kiln head and end sections, solving problems of return materials and dust leakage.
Stable Quality
Limestone is uniform in heat, stable in product quality, low in over-burnt rate, especially suitable for calcination of high activity lime for steelmaking.
Flexible Process
Vertical preheater can be configured to make full use of high-temperature flue gas, preheat limestone, and improve product activity.
Working Principle
Limestone is fed into the kiln through the chute at the end of the kiln. Due to the tilt and slow rotation of the kiln body, the limestone rolls along the circumference on one side and moves from the end to the kiln head along the axis. The fuel is sprayed into the kiln from the burner for combustion, and heat is transmitted to the limestone by radiation, convection and conduction. After the limestone is calcined into quicklime during the moving process, it is discharged from the end of the kiln, and the high-temperature flue gas enters the dust removal system.
The working principle of the Lime Rotary Kiln reflects our commitment to engineering excellence. Each component is precisely designed and manufactured to ensure optimal performance, energy efficiency, and minimal maintenance requirements. The integrated control system allows for easy operation and monitoring of all key parameters.
