| 摘要 |
The invention relates to a process for manufacturing brickworks mouldings by mixing a moulding compound consisting of a granular clay-containing material with a lean material and, if required, other additives from which moulding compound green products are moulded, which are dried and burnt, which process permits a recycling of residual materials by using as clay-containing material a residual material consisting predominantly of clay minerals, especially a dry fraction, consisting predominantly of annealed clay minerals, of an ash, preferably brown coal ash, and by producing the moulding compound by mixing the fraction with the lean material and other additives as well as water, water being used in a quantity such as to produce an earth-moist moulding compound which is then pressed in portions on a press to form individual, inherently stable green products.
