The article presents the results of the preliminary analysis of the algebraic sensitivity of the model describing the change in the limit values ​of densification stress in the process of dry ice agglomeration using multi-channel dies in the reciprocating technique. In the available literature, it was noted that the limit value of compaction stresses significantly exceeds the effective value. This justifies the sense of undertaking work on the development of a multi-channel die that allows the reduction of the value of the indicated stress, which will reduce the consumption of electricity necessary for the production of dry ice pellets. The sensitivity analysis performed is related to the attempt to determine the significance of the impact of individual geometric parameters of the multi-channel die on the value of the limit stress. The results will significantly contribute to the development of a work program related to the optimization of geometrical parameters of the tools used to implement the indicated process.
