circuit crushing is designed to avoid the formation of excessive amounts of fine particles and dust and to minimize energy consumption, especially at high degrees of fineness applied in one crusher (Grzelak, [ 37 ] Kurdowski [ 38 ] ).
Scheme of the model jaw crusher: 1a, 1b – crushing plates, 2a – fixed jaw, 2b – moving jaw, 3a, 3b front end rear toggle, 4 – pitman, 5 – eccentric shaft, a, b– width and length of the inlet slot, I – force measurement system, II – moving jaw displacement measurement system
Crushing forces were measured by means of
