Abstract. This paper presents the results of research on improving the effectiveness of the agglomeration process. Improving effectiveness was obtained as a result of the application of the convergent sleeve. The sleeve is mounted before the multi-holes die in the dry ice agglomeration machine. The empirical part of the paper presents the results of research on which FEM model was based. The numerical part of research presents the FEM model of the agglomeration process. The FEM model with a known uncertainty level was used to determine the influence of geometrical parameters of the sleeve on the limit value of the agglomeration forces. The model will be one of the starting points for the design and construction of the machine for the compaction and granulation of dry ice.

The study presents a control and measurement system for the drive parameters of screw compactor machine with open working chamber for shredded materials. The study demonstrates the construction and working principle of the force sensor for measuring the axial force at the compacting screw. The calibration method for the measuring system was presented together with example measurement results for compaction of broken up rye straw, oat straw and hay. The study results were analyzed for feasibility of use for the compaction of materials with specific thermomechanical properties. The conclusion presents the possible forms of application of the established solution in mass production.

“…Powders and shredded materials need to be compacted to give them the appropriate geometrical form and mechanical properties [9][10][11][12][13][14][15]. The manufacturing of renewable solid fuel from broken down lignocellulosic materials requires proper preconditioning of the material, breaking it down, drying and mixing.…”

The study presents the possibility to measure the torque and axial force of the working system of the screw compactor machine with open working chamber. Attention was drawn to the relationship between the two parameters and the geometric properties of the working system and the thermomechanical properties of the compacted materials. A functional construction coefficient was proposed and defined to bound together the value of torque and axial force. Its usability was demonstrated for identifying the parameters of compaction process together with its applicability for controlling these types of processes.
