The article includes authors’ further thermography studies on the classical pillow-shaped briquetting process (instead of the saddle-shaped ones that were previously conducted) of four materials (calcium hydroxide and water mixture, mill scale, charcoal fines and starch mixture, as well as a mixture of EAFD, scale, fine coke breeze, molasses, and calcium hydroxide). However, it is known that the pressure exerted on the briquette is different for different compaction systems. Nevertheless, the distribution of stress in the briquetting material is still a subject of scientific study. ![]() The distribution of temperature on the surface of the briquettes may determine the pressure used locally on them. ![]() By the process of generating different types of pressure on the surface of briquettes, their compaction is different as well. The pressure of the unit is not constant and the changes in value depend on a given place on the molding surface. This parameter is a result, among other factors, of the geometry of a compaction unit and also the properties of the consolidated material. ![]() When the briquetting process of fine-grained material takes place in the roller press unit, the pressure reached is over a hundred megapascals. ![]()
