<p>A method for the production of construction articles and preparation of a mixture for making them from a clay raw material, providing for production of two kinds of granules: one from a mixture of clay, limestone and coal, and the other from clay, and burning them using said coal up to different temperatures. Then the burnt product is moistened and construction articles are formed, for example bricks, with subsequent treatment in an autoclave or a steam chamber. A technological line is also proposed, as well as a method for burning a mixture and a construction article obtained by said method, and a device for burning characterized by the absence of a heat-resistant lining.</p> |
