Carbon Rotary Kiln Introduction

What is carbon? Carbon is a non-metallic element (symbol C) widely present in nature. It is a non-metallic solid material formed by the combination of carbon and graphite. It generally features high conductivity and corrosion resistance, making it an ideal material for high-temperature and extreme environments. It is mainly used in the production of graphite electrodes, carbon radiators, carbon fibers, electric brushes, impermeable graphite, etc.

How is carbon produced? This brings us to the carbon rotary kiln.
The carbon rotary kiln is a crucial industrial equipment for high-temperature processing of carbonaceous materials. The cylinder is generally made of high-quality heat-resistant steel, with high-temperature refractory material lining the interior to ensure structural stability and thermal insulation performance in high-temperature environments. Carbonaceous materials enter from the kiln tail and are uniformly heated at high temperatures through the slow rotation of the rotary cylinder, completing processes such as calcination, graphitization, or activation. The carbon rotary kiln has the advantages of large production capacity, simple operation, stable operation, high thermal efficiency, and strong adaptability to materials, and is widely used in the electrode, lithium battery anode material, and metallurgical industries.

Carbon Rotary Kiln Working Principle

The working principle of a carbon rotary kiln is that carbonaceous materials are poured into a tilted rotating cylinder from a feed pipe located at the kiln tail (the high-end position of the kiln). The carbonaceous materials undergo a composite motion, allowing them to continuously complete calcination or graphitization treatment at high temperatures. During the movement of materials, they undergo multiple stages such as drying, preheating, decomposition, and calcination, completing a series of physical and chemical changes, and ultimately becoming qualified clinker, which is discharged from the kiln head into the cooler for cooling. Finally, the high-purity carbon material after calcination is discharged from the kiln head, and the exhaust gas is treated by the kiln tail dust removal and purification system to achieve continuous production.

Carbon Rotary Kiln Advantages

Reasonable structural design: The carbon rotary kiln adopts advanced and unique hydraulic gear devices. The kiln body is made of high-quality steel plates rolled, and refractory bricks are embedded inside, which not only ensures the strength and sealing of the kiln body, but also effectively resists the erosion of high-temperature materials and flames. The service life can be extended by at least three times.
Large production capacity: Carbon rotary kilns have diverse specifications and sizes, simple structures, stable processes, high output, easy operation, and high efficiency. They can continuously process large amounts of carbonaceous materials and meet the needs of large-scale industrial production.
High thermal efficiency: The kiln body is usually equipped with an insulation layer on the outside, which can maintain a moderate temperature, reduce heat loss, and lower energy consumption and production costs.
Easy and flexible operation: The carbon rotary kiln has heat exchange function and automatic temperature monitoring function, which can monitor and adjust the temperature, pressure, speed and other parameters inside the kiln in real time. Various raw materials can be processed by adjusting the process parameters, with high flexibility.
Good environmental performance: efficient dust removal equipment and exhaust gas treatment system are used to purify the dust and harmful gases generated in the kiln, making them meet emission standards and reducing environmental pollution.

The common faults of active lime calcination rotary kiln mainly include the following:

Cylinder deformation: Due to long-term high-temperature operation, uneven heating, or mechanical stress, the cylinder may deform, affecting the normal operation and sealing performance of the equipment:

Wheel and Belt Faults: For example, overheating of the wheel bearing, uneven wear of the wheel, cracking of the belt, etc., can affect the smooth operation of the rotary kiln.
Transmission System Faults: Such as gear wear of the reducer, damage to the coupling, motor failure, etc., may lead to transmission failure.
Failure of Sealing Device: Aging, wear or improper installation of sealing components can cause gas leakage inside the kiln, affecting thermal efficiency and working environment.
Damage to Refractory Materials: Long term high temperature and material erosion may cause the refractory materials in the kiln to fall off or break, affecting the insulation effect and service life of the kiln body.
Circles and Nodules: Abnormal adhesion and accumulation of materials in the kiln, forming rings and nodules that hinder the normal flow and heat transfer of materials.
Combustion Device Malfunction: Burner nozzle blockage, unstable fuel supply, incomplete combustion, etc., affecting calcination efficiency and energy utilization efficiency·

For these common faults, regular equipment inspections, maintenance, and upkeep are required to ensure the stable operation and long-term use of the rotary kiln.
