Activated Carbon Making Machine is specialized equipment used to convert raw materials such as wood, coconut shell, nutshells, coal, and bamboo into high-quality activated carbon. Due to its large surface area, developed pore structure, and excellent adsorption performance, activated carbon is widely applied in water treatment, air purification, food decolorization, gold recovery, chemical industry, and pharmaceuticals.

With the increasing global demand for activated carbon, the use of modern activated carbon equipment not only greatly improves production efficiency but also achieves energy saving and emission reduction, fully meeting the trend of green and sustainable development.

2. Production Principle of Activated Carbon

The manufacturing process of activated carbon mainly includes carbonization and activation stages:

1. Carbonization Stage
   The raw materials are heated in a low-oxygen or oxygen-free environment at 400℃–700℃, undergoing pyrolysis to remove moisture and volatile substances, forming initial carbonized material (char).
2. Activation Stage
   The carbonized material is further treated at 800℃–1100℃ with steam, carbon dioxide, or chemical agents to remove non-carbon impurities and develop a porous structure, resulting in activated carbon with strong adsorption ability.

The activated carbon making machine is designed based on these two fundamental processes.

3. Main Components of Activated Carbon Making Machine

A complete activated carbon production line usually consists of the following systems:

1. Raw Material Processing System
   • Crusher: Crushes wood, coconut shell, nutshell, coal, etc. into suitable particle sizes.
   • Dryer: Removes moisture to improve carbonization efficiency.
2. Carbonization Furnace
   • Types: Vertical carbonization furnace, continuous carbonization furnace, rotary kiln carbonization furnace.
   • Function: Converts raw materials into char while recovering combustible gas for heating, reducing fuel consumption.
3. Activation Furnace
   • Types: Rotary activation furnace, multi-stage furnace, vertical furnace.
   • Function: Develops micropores in the carbonized material by introducing steam or CO₂ under high temperatures.
4. Cooling & Screening System
   • Prevents freshly activated carbon from burning when exposed to air.
   • Classifies the finished product into powder, granular, or pellet activated carbon.
5. Exhaust Gas Treatment System
   • Includes dust collector, scrubber, and flue gas purification devices.
   • Ensures compliance with environmental protection standards.
6. Automatic Control System
   • PLC control with user-friendly interface.
   • Enables intelligent regulation of temperature, atmosphere, and feeding.

4. Advantages of Activated Carbon Equipment

Compared with traditional manual or simple kiln methods, modern activated carbon machines offer significant advantages:

1. Energy Saving & Eco-Friendly – Waste gas recycling and smoke purification system.
2. High Automation – PLC control reduces labor intensity and improves safety.
3. Stable Product Quality – Produced activated carbon features high porosity and stable adsorption value, iodine number up to 800–1200 mg/g.
4. Wide Raw Material Adaptability – Coconut shell, nutshell, wood, bamboo, and coal can all be processed.
5. High Economic Benefits – Strong market demand and fast investment return.

5. Suitable Raw Materials

The activated carbon manufacturing machine can process a variety of raw materials, such as:

• Coconut shell activated carbon
• Nutshell activated carbon (walnut, apricot, almond shells)
• Wood-based activated carbon (wood, bamboo, sawdust)
• Coal-based activated carbon (anthracite, bituminous coal)
• Other agricultural & forestry wastes (palm shell, rice husk, etc.)

6. Applications of Activated Carbon

1. Water Treatment – Removes chlorine, color, odor, and organic pollutants from drinking and industrial water.
2. Air Purification – Used in air purifiers, industrial exhaust treatment, and automobile emission control.
3. Gold Recovery – Widely applied in mining CIP/CIL processes for gold adsorption.
4. Food & Beverage – Decolorization and purification of sugar, wine, edible oils.
5. Medical & Chemical Industry – Used for pharmaceuticals, solvent recovery, and gas separation.

7. Market Prospects

With stricter environmental regulations, higher standards for wastewater treatment, and growing demand for air purification, the global activated carbon market is expanding rapidly. In the next 5–10 years, activated carbon making machines will see significant growth opportunities in Asia, Africa, and South America.
