What is Coal Based Activated Carbon? What Kind of Grinding Equipment is Generally Used?

Coal-based carbon (also called coal-based activated carbon) is a porous carbon material. It is made from coal (such as anthracite, bituminous coal, etc.) through a series of physical or chemical methods. Due to its highly developed pore structure, large specific surface area, and good adsorption performance, coal-based carbon is widely used. It is applied in water treatment, air purification, decolorization, deodorization, solvent recovery, and as a catalyst carrier, among other fields.

Main Characteristics of Coal Based Activated Carbon

• High Adsorption Performance:
  Coal-based carbon has a developed pore structure. It effectively adsorbs impurities and pollutants from gases and liquids.
• High Strength and Wear Resistance:
  Coal-based carbon typically has high mechanical strength and wear resistance. It is suitable for use in various industrial environments.
• Acid and Alkali Corrosion Resistance:
  Coal-based activated carbon has some resistance to acid and alkali corrosion. It is applicable in various chemical environments.
• Good Regeneration Performance:
  Coal-based carbon can be regenerated through thermal or chemical methods. This restores its adsorption performance and extends its service life.

Processing Technology of Coal Based Activated Carbon

• Raw Material Selection:
  Suitable coals, such as anthracite and bituminous coal, are selected as raw materials.
• Carbonization:
  The crushed coal is subjected to carbonization at high temperatures (usually 600-900°C). This removes volatile components, resulting in the initial carbonized material.
• Activation:
  The carbonized material undergoes activation through either physical methods (e.g., steam or CO2 activation) or chemical methods (e.g., zinc chloride or phosphoric acid activation). This increases its porosity and specific surface area.
• Post-Processing:
  After activation, the coal-based carbon undergoes washing, drying, and screening to obtain the final product.

Coal-based Activated Carbon Preparation

Coal-based activated carbon grinding typically uses the following equipment:

Raymond Mill:

Applicability: Raymond mills are suitable for grinding materials with low hardness and low moisture. Coal-based carbon has medium hardness, making it suitable for fine and ultrafine grinding with a Raymond mill.

Features: The Raymond mill is efficient, energy-saving, and easy to operate. It produces coal-based carbon powder with a fineness of 80-400 mesh.

Ball Mill:

• Applicability: Ball mills are suitable for grinding materials with higher hardness and larger particle sizes. They are commonly used for both coarse and fine grinding of coal-based carbon.
• Features: The ball mill has a simple structure and broad applicability, but it consumes more energy.

Vertical Roller Mill (VRM):

• Applicability: Vertical roller mills are ideal for large-scale production and fine grinding. They are an efficient choice for fine and ultrafine grinding of coal-based carbon.
• Features: The VRM has a small footprint, low energy consumption, and low noise. However, the equipment investment is relatively high.

Superfine Grinding Mill:

• Applicability: Superfine mills are suitable for processing coal-based carbon powder with high fineness and purity. They can produce ultrafine coal-based activated carbon powder with a fineness above 400 mesh.
• Features: The superfine grinding mill offers high fineness, large output, and low energy consumption. However, it requires higher maintenance.
