Process for recycling esp. asbestos contg. cement materials

摘要

Cement-bonded materials, partic. asbestos cement, are recycled by a process in which the materials are used as at least one starting material for combustion to mfr. cement clinker. Water contg. raw sludge is prepd. in tube mills and is used in the rotary kilns normally applied for clinker formation by the wet process. Filter equipment for specific fibres is provided for the treatment of waste gas in the dry stage of the process to remove any asbestos fibres that are present.
