    Manufacturing processes of artificial lightweight

    Aug 01, 1986 An overview is given on manufacturing processes of artificial lightweight aggregates from fly ash. Agglomeration techniques and hardening methods are described. ... Sintering of green pellets can also be effected using types of equipment other than a sintering grate. These include rotary kilns and shaft kilns, such as those employed in the

    US5342442A - Lightweight aggregate from flyash and

    A method is shown for producing a lightweight aggregate by treating flyash and sewage sludge. The flyash and sewage sludge are mixed together and then agglomerated into pellets, with or without the use of a binder. The pellets may be coated and then are dried. The dried pellets are introduced into a rotary kiln in a direction that is co-current with the flow of fuel and air through the kiln

    The Deposit Formation Mechanism in Coal-Fired Rotary Kiln

    Due to its lightweight and fine particle size [49,50], the coal ash floats towards the tail of the rotary kiln with the airflow, finally scattering on the rolling pellet layer and the kiln lining . In particular, the SiO 2 , Al 2 O 3 and CaO in deposits mainly come from coal ash
