The technological parameters were determined for the production by the foam method of a lightweight granulated filler of apparent density 0.5-0.7 g/cm from raw kaolin without the addition of a nonplastic material to the batch. When the operations are carried out separately, the duration of the production cycle is 2.5-3 h, which includes the firing of the porous lump material by passing flue gases through a layer up to 500 mm in depth and demonstrates that in principle it is possible to set up a line for the production of foam-kaolin filler by the new method. The filler can be used, e.g., with good results as aggregate for heat-insulation concrete. [ABSTRACT FROM AUTHOR] |
