Detection of bridging in gyratory or cone crusher
A method, crusher, computer program and crushing plant, in which bridging generated on an arm is detected in a crusher that has a body, an outer wear part fixed to the body, an outer wear part fixed to the body; a support cone rotatable inside the body via a main shaft); an inner wear part on a cone...

| description | A method, crusher, computer program and crushing plant, in which bridging generated on an arm is detected in a crusher that has a body, an outer wear part fixed to the body, an outer wear part fixed to the body; a support cone rotatable inside the body via a main shaft); an inner wear part on a cone surface of the support cone; and a support of the support cone. The support contains a group of arms inside the body and extending inwards from the body; a main shaft radially supported to the arms; and a thrust bearer supported by the arms for supporting the main shaft and for axially supporting the support cone via the main shaft. The crusher crushes mineral material between the inner wear part and the outer wear part. Measurement information is received describing stress of the support of the support cone; and bridging formed onto an arm is detected from the measurement information. |
