Rotary kiln is the most important production equipment in activated carbon plants, which can directly affect the quality and output of activated carbon. Based on different production stages, the activated carbon rotary kiln can be divided into biomass carbonization rotary kiln, carbon activation rotary kiln, and activated carbon regeneration rotary kiln. They respectively meet customers’ production needs in different process stages.
Biomass Carbonization Rotary Kiln
Production Stage: biomass material carbonization
Production Principle: biomass material is decomposed at a high temperature inside the rotary kiln to discharge non-carbon substances, finally forming fixed carbon with a skeleton structure and a certain strength.
Carbon Activation Rotary Kiln
Production Stage: carbon activation
Production Principle: carbon contacts water vapor and other oxidizing gases under a high temperature inside the rotary kiln, until a developed pore structure is formed, which has a strong adsorption capacity.
Activated Carbon Regeneration Rotary Kiln
Production Stage: waste activated carbon reactivation
Production Principle: adsorbed saturated activated carbon contacts water vapor and oxygen at high temperatures inside the rotary kiln so that the organic matter blocked in the carbon is removed and its adsorption performance is restored.

Biomass Carbonization Rotary Kiln
AGICO carbonization rotary kilns can be divided into indirect fired rotary kilns and direct fired rotary kilns.
Production Process:
After the biomass material gets into the carbonization rotary kiln, they move slowly from the feeding port to the discharging port, depending on the inclination and rotation of the kiln body, and gradually passes through the drying zone, the pyrolysis zone, and the carbonization zone. In this process, the carbonization kiln heats the material through thermal radiation so that the material is decomposed at a high temperature to discharge non-carbon substances such as oxygen and hydrogen and finally form fixed carbon.

Carbon Activation Rotary Kiln
Production Process:
With the rotation and inclination of the kiln body, the carbon passes through the preheating zone and enters the activation zone, where it contacts water vapor and oxygen at a high temperature and then a developed pore structure is formed inside. After that, it gets into the discharge pipe of the cooling zone, gradually cools down to 200 ℃, and then automatically slides down to a water cooling device outside the kiln to reduce to a normal temperature.

Activated Carbon Regeneration Rotary Kiln
Production Process:
With the rotation and inclination of the kiln body, the waste activated carbon slowly passes through the preheating zone (drying) and enters the carbonization and desorption zone. At this stage, water vapor and oxygen penetrate through the waste activated carbon and undergo a gasification reaction with it so that the micropore surface is cleaned and its adsorption performance is restored.
