This article describes the existing methods of pelletizing. Their main methods and mechanisms are considered. The technologies of pellet formation are described in detail. In the work, the materials on the development of the technology of cold agglomeration of gas cleaning sludge in a mixture with rich dust of inertial collectors and dust after drying chrome ore were used as the studied materials. The material is a bulk substance obtained after drying chrome ore. The chemical composition of finely dispersed chrome raw materials is given. The binder is an organic substance, a solid and amorphous material polyacrylamide, which is a polymer based on acrylic acid amide, odorless, powder with a size of less than 1 mm, cement grade M400 / B22.5, clay powder for chrome pellets and inorganic binder EB. A comparative analysis and differences between the binders were made. The results of laboratory studies on agglomeration were also obtained. The pellets were tested for dropping, on a dropping strength tester, for impact and abrasion. The results of pellet strength tests are presented, the results are presented on the graph. The quality indicators of the obtained products and their resistance to transportation and multiple refills were assessed. The optimal mixture composition for pelletizing was selected.
