Study of Samples Strength of Material Formed by the Processes of Compaction, Extrusion and Tumbling Granulation

Abstract

In a period of industrial expansion, protection of the environment is often neglected during the mass manufacture of products. One of the problems of our society that is necessary to face at present is the provision, processing and then usage of waste composed of fine particles that are extremely dangerous for mankind. This study looks at the processing of the fine dust resulting from the manufacture of brake pads. The selected technologies for the process of dust treatment were compaction, extrusion and tumbling granulation, and their consequent comparison with the strength of a break and disintegration of agglomerates from fine dust. The experiments were performed on a unique equipment that made it possible to process such dust in the form of larger units and thus reduce their dustiness, with this dust being reintroduced into the technologies for repeat processing or used for energy processing, in a cement kiln, for example.

Research on Load on the Roll Press’ Shafts and Work Items

“…where δ is width between rollers in the makeshift layout, sb is the briquette compaction degree. Unit pressure course measurements were conducted in various scientific centres [10,[21][22][24][25][26][27]] and aimed at optimisation of the compacting process of pharmaceuticals in a roll press equipped with smooth rollers [1]. In order to assess a theoretical unit pressure course for compacted material, such as municipal sewage sludge, the nip angle α0 value as well as case-specific empirical formulas  =f(s) and μk=g(s) [18] must be determined.…”
