Method for emptying an inertia cone crusher

摘要

A method for at least partly emptying a crushing chamber formed between an inner crushing shell and an outer crushing shell of an inertia cone crusher is provided. The inner crushing shell is supported on a crushing head. A central axis of the crushing head gyrates about a gyration axis with an rpm, for crushing material in the crushing chamber. The method includes the steps of interrupting the feeding of material to the crusher; measuring, directly or indirectly, at least one of a position and a motion of the crushing head during an amplitude control period; comparing the measured position and/or motion with at least one set point value; determining, based on the comparison, the measured position and/or motion to at least one set point value, whether the rpm should be adjusted; and adjusting the rpm when necessary.

1. A method for at least partly emptying a crushing chamber formed between an inner crushing shell and an outer crushing shell of an inertia cone crusher, the inner crushing shell being supported on a crushing head, said crushing head being rotatably connected to an unbalance bushing which is rotated by a drive shaft, said unbalance bushing being provided with an unbalance weight for tilting the unbalance bushing, such that a central axis of the crushing head will gyrate about a gyration axis with a rpm, crushing material in the crushing chamber, the method comprising the steps of:
interrupting feeding of material to the crusher; measuring, directly or indirectly, at least one of a position and a motion of the crushing head during an amplitude control period; comparing the measured position and/or motion to at least one set point value; determining, based on said comparing the measured position and/or motion to at least one set point value, whether said rpm should be adjusted; and adjusting, when determined necessary, said rpm.
