POWDER AND PARTICLE PROCESSING – Applications – Chemicals – Activated Carbon Processing of Activated Carbon Activated carbon seen through an SEM microscope Activated carbon is an industrially manufactured, carbonaceous product that has a porous structure and an extremely large inside surface. This can range from 500 to 1500 m²/g. Activated carbon is used to absorb undesirable or noxious colouring, flavouring and odorous substances from gases, vapours and liquids, and also to recover valuable solvents in the chemical fibre, paint, synthetic resin and the metal producing and working industries, etc. In the pharmaceutical industry, activated carbon is used to absorb toxic substances in the gastrointestinal tract (carbo medicinalis). The system below was designed and delivered for processing activated carbon recovered from wood chips. The feed size is less than 2.5 mm. The required end-product fineness is 90 % < 175 µm, whereby a max. of 20 % < 45 µm is permitted. The required system performance is 300 - 400 kg/h. A combination comprising a fluidised bed opposed jet mill AFG and a Turboplex classifier ATP meets the requirements. Because of the abrasive nature of activated carbon, the product-contact system components are protected with PU elements and the classifying wheels are in aluminium oxide design. Zoom with legend
