Abstract
Abstract
Manufacturing of ceramic goods most often involves compaction of granulated powder. There are numerous phenomena that complicate rheological equations of densification during the compaction process and therefore render these equations practically useless without computer assist. We present a simple generalized model of densification of granulated ceramic powder based on Ballhausen-Gąsiorek’s, Messing’s and Pascal’s models. Experiments have proven a linear variation of density along the direction of compression and changes of dynamic and kinematical coefficients of friction. The variation of the dynamic coefficient of friction is in the range from 0.15 to 0.25.
