METHOD OF CONTROLLING AN INERTIA CONE CRUSHER

摘要

A method of controlling the crushing of material (49) in an inertia cone crusher (1) comprising  charging (100) material (49) to be crushed from a feeding hopper (50) to a crushing chamber (48) formed between an inner crushing shell (18) being supported on a crushing head (16) and an outer crushing shell (12) of the inertia cone crusher (1);  rotating (112) an unbalance bushing (26) which is provided with an unbalance weight (30) and rotatably connected to the crushing head (16) by a drive shaft (38) such that a central axis (S) of the crushing head (16) gyrates about a gyration axis (C);  sensing (114) the number of revolutions of the unbalance bushing (26) using an rpm sensor (47);  controlling (1 16) the number of revolutions of the unbalance bushing (26) using a control system (46); and  crushing (118) material in the crushing chamber (48).
