Abstract
A method for detecting wear in crushers, having a wearing part (2) mounted on a drive shaft (1), during idle operation is described in which downtimes that impair crusher productivity can be eliminated and nevertheless reliable wear detection is made possible with low risk of injury to machine operators. The drive shaft (1) is accelerated from a starting angular speed (ω1) to an end angular speed (ω2) with a specified acceleration, and the drive energy required for this is ascertained, whereupon the wear of the wearing part (2) is ascertained as the value assigned to the required drive energy in a specified wearing-part characteristic curve (3, 4, 5).
Claims18
A method for detecting wear in a crusher in idle operation, the crusher having a wearing part mounted on a drive shaft, said method comprising:
- accelerating the drive shaft from a starting angular velocity (ω1) to an end angular velocity (ω2) with a predetermined acceleration;
- and
- determining the drive energy required for the accelerating;
- and
- determining the wear of the wearing part as a value associated with the required drive energy in a predetermined wearing-part characteristic curve.
