The unit pressure in the fine-grained material consolidation process in the roller press can reach over hundred MPa and is a parameter which results, among other things, from the properties of the consolidated material and the compaction unit geometry. The distribution of temperature on the surface of the briquettes may testify the pressure used locally on them. However, it is known that the pressure exerted on the briquette is different for different compaction systems. The aim of the work was to analyze the briquetting process of fine-grained materials in a roller press equipped with saddle-shaped briquette-forming rollers based on the conducted thermography studies. The tests were carried out on the forming rollers described in patent PL 222229 B1. The end point of the work was to show different temperatures on the surface of briquettes. Two mixtures of hydrated lime with water, a mixture of scale and a mixture of iron-bearing dust were used for the tests. In most mixtures, the highest temperatures were achieved in the middle-upper part of the briquettes.
