Abstract
A method of determining wear of a rotary impact crusher includes adjusting the position of an impact rocker relative to an impact rotor with an actuator by a first adjustment value until a crushing section of the impact rocker contacts an impact bar or an impact circle of the impact rotor. The first adjustment value is compared to a first reference value to make a first comparison corresponding to total wear of the impact rocker and the impact bar. The position of the impact rocker is adjusted relative to the impact rotor by a second adjustment value until the impact rocker contacts a reference measurement section. The second adjustment value is compared to a second reference value to make a comparison corresponding to wear of the impact rocker.
Claims18
A method of determining wear of a rotary impact crusher, the rotary impact crusher including:
- an impact rotor and at least two impact bars connected to the impact rotor, the impact bars each having a radially outer end, wherein the radially outer end of at least one of the impact bars forms an impact circle during rotation of the impact rotor;
- at least one impact rocker operably associated with the impact rotor such that in an operating position a crushing gap is formed between the impact circle and a crushing section of the at least one impact rocker;
- and
- an actuator configured to adjust a position of the at least one impact rocker relative to the impact rotor;
- wherein the method comprises steps of:
- (a) adjusting the position of the at least one impact rocker relative to the impact rotor with the actuator by a first adjustment value until the crushing section of the at least one impact rocker contacts the at least one of the impact bars or the impact circle;
- (b) comparing the first adjustment value to a first reference value to make a first comparison corresponding to total wear of the at least one impact rocker and the at least one of the impact bars;
- (c) adjusting the position of the at least one impact rocker relative to the impact rotor by a second adjustment value until the at least one impact rocker contacts a reference measurement section defined on the impact rotor;
- and
- (d) comparing the second adjustment value to a second reference value to make a comparison corresponding to wear of the at least one impact rocker.
