Method of controlling an inertia cone crusher

摘要

A method of controlling the crushing of material in an inertia cone crusher includes the step of charging material to be crushed from a feeding hopper to a crushing chamber formed between an inner crushing shell being supported on a crushing head, and an outer crushing shell of the inertia cone crusher. An unbalance bushing, which is provided with an unbalance weight and rotatably connected to the crushing head by a drive shaft, is rotated such that a central axis of the crushing head gyrates about a gyration axis. The number of revolutions of the unbalance bushing is sensed using an rpm sensor. The number of revolutions of the unbalance bushing is controlled by a control system and the material is crushed in the crushing chamber.

1. A method of controlling crushing of material in an inertia cone crusher, comprising the steps of:
charging material to be crushed from a feeding hopper to a crushing chamber, the crushing chamber being formed between an inner crushing shell supported on a crushing head, and an outer crushing shell of the inertia cone crusher; rotating an unbalance bushing, which is provided with an unbalance weight and rotatably connected to the crushing head, by a drive shaft, such that a central axis of the crushing head gyrates about a gyration axis; sensing the number of revolutions of the unbalance bushing using an rpm sensor; controlling the number of revolutions of the unbalance bushing using a control system; sensing a power value of the inertia cone crusher; applying a constant power input to the inertia cone crusher by adjusting the number of revolutions of the unbalance bushing; and crushing material in the crushing chamber.
