METHOD FOR PRODUCTION OF CONSTRUCTION ARTICLES AND DEVICE FOR BURNING

摘要

The present invention relates to a process for the manufacture of building products (elements) and mortar application compositions from clay-like raw materials. The object of the invention is a reduction in the bulk of the equipment and in the energy consumption. According to Figure 1, two types of small grains (granules) of clay, limestone and coal are granulated by the granulators (21), (22), which grains are caused by the said coal to burn at different temperatures in a device (31), which is characterised in that it has no lining (cladding). The burnt product is moistened and stirred up, whereupon bricks are formed in a press (49) and treated in an autoclave or in a steaming chamber (51). The brick produced in this way has pleasing aesthetic properties. A Portland cement with additives can be produced in the device (31) without cladding.
