The purpose of the work is innovative rhombus briquetting mechanism model development. Mechanism model simulation is a tool for the transition from the prototype to the real machine design. For simulation Working Model 2D software was used. The Working Model 2D software is capable of modelling the motion of rigid bodies that may be connected by a variety of joints and constraints. For simulation result evaluation energy consumption for pressing cycles was determined as 2.6 kJ for laboratory experiment and 2.5 kJ for simulation. Difference in the energy consumption results is 4 % for 6.5 grams briquette pressing.
