EPC solution for activated carbon manufacturing
Columnar Activated Carbon Production Line
CAPACITY: 3-30tpd
EQUIPMENT: ball mill, mixer, activated carbon rotary kiln, screener, packer, etc.
Columnar activated carbon is a hot-sale absorbing material, it is widely applied in many fields, such as wastewater treatment, air purification, desulfurization and denitrification, food processing, etc. Based on the increasing market demand and profitability of activated carbon at this stage, investment in activated carbon production lines has become popular.
Characteristics of columnar activated carbon
- High adsorption performance: Columnar activated carbon has a high surface area and high porosity, which can adsorb a large number of harmful substances such as organic matter, heavy metal ions, ammonia nitrogen in the water, and also the volatility organic compounds, smoke, odors, etc. in the air.
- High mechanical strength: Columnar activated carbon has good mechanical strength, is not easily broken, can withstand large pressure and friction, and is suitable for various application scenarios.
- Long life: The adsorption function of columnar activated carbon is not easily saturated and can be used for a long time, usually up to 3-5 years.
- Easy to regenerate: The adsorption function of columnar activated carbon can be regenerated through high-temperature steam or chemical agents, reducing the cost of use.

The process technology route for producing columnar activated carbon, regardless of the type of activated carbon product, can be roughly divided into five steps: raw material preparation, kneading and shaping, carbonization, activation, and finished product post-treatment. The following will introduce the main production processes.
STEP1- Raw material preparation
The raw material preparation process refers to the process of crushing, screening, or crushing qualified raw materials (raw coal or semi-coke) purchased from outside to prepare raw coal with qualified particle size. The so-called qualified particle size is generally 2-6mm for crushed carbon, while formed carbon should be made into powder with at least 180 mesh sizes. At present, the powder making equipment used in the domestic activated carbon industry mainly includes ball mills, vibration mills, suspended roller pendulum mills (Raymond mills), and airflow crushers.
STEP2- Kneading process
The kneading process refers to the production of columnar activated carbon. Pinching is the process of thoroughly stirring qualified coal powder with a certain amount of binder and additives at a certain temperature to form a uniform paste. The mixed paste is extruded under a certain pressure to form a certain diameter of raw carbon strips, which are called mold. At present, the commonly used kneading machine in China is the Z-type mixer, while the forming equipment often uses two or four columns hydraulic press.
STEP3 – Carbonization process
The equipment used in the carbonization process is called a carbonization furnace. At present, commonly used carbonization furnaces both domestically and internationally include internally heated rotary furnaces, fluidized bed furnaces, and rake furnaces.
STEP4 – Activation process
At present, the types of activation furnaces used in the gas activation method for producing coal-based activated carbon mainly include rake furnaces, skip furnaces, rotary furnaces, fluidized bed furnaces, and Stoke furnaces. The Slump furnace, also known as a vertical moving bed activation furnace, is based on the basic principle that the raw materials move downwards along the vertical material channel with the help of their own gravity, continuously contacting the horizontal direction of superheated water vapor during the movement process to achieve activation reaction. Its biggest advantage is self-thermal equilibrium, which means that there is no need for an external heat source in production, and a combustion reaction occurs between the quantitative air added outside the furnace and the water gas generated by the activation reaction. The heat generated by the combustion reaction is used to supplement the heat lost due to the heat absorption of the activation reaction.
STEP5 – Product handling
Post-treatment of finished products is mainly aimed at improving or enhancing product quality or characteristics of activated carbon. According to the characteristics of raw coal and the quality requirements of the produced products, the post-treatment process of finished products mainly includes processes such as acid washing, impregnation, drying, crushing, screening, powder making, and packaging. Acid washing and soaking are both aimed at improving the product quality of columnar activated carbon. The former is mainly to reduce the ash content of the finished activated carbon, and sometimes to adjust the pH value of the product. The latter mainly improves the surface adsorption characteristics of activated carbon. Drying is a necessary processing step for the finished carbon after acid washing or soaking. For the production of general activated carbon products, the post-processing of finished products mainly includes processes, such as crushing, screening, powder making, and packaging.
