Activated carbon is created during the coal production process. Powder Activated Carbon is typically ground and then sized to specified requirements. Activated carbon is used in plating solutions, water and air purification, and even in toothpaste, mainly due to its adsorption properties. Screening activated carbon can be a simple process when separating out coarse fractions. For fine separations of activated carbon, energy and finesse is required to get particles to efficiently separate out into the desired fractions.
