The increase in demand of industrial salt by internal and external beneficiaries, the increase of the diversity of salt that is demanded and the physical and moral wear of the existing pre-grinding station (functioning since 1997) compels the Ocna Dej salt mine to fiind a new grinding flux, which is to be modern, have increased productivity and quickly shift from one sort of salt to another sort of salt. This paper presents a basic chart of the grinding installation for a capacity of production of 300 tons/hour for the sorts of salt of 0 – 15 mm and 0 – 4 mm. The paper also presents the sizing stages of the 800 mm roller conveyers for lengths up to 100 metres and angles of up to 30 degrees and 3D modellation of its elements in order to obtain an easy and fast flux of transportation of the installation.
