Hello everyone.
My questions are regarding to maintenance of the primary gyratory crushers.
Does anybody know any kind of sensor to monitoring head spin of the main shaft of the primary gyratory crusher?
During the measurement of the spider bushing clearance, I need to remove the spider cap and then check clearance using a feeler gauge. (Please the picture attached).
It takes me more than 2 hours to do that. I would like to know if anybody knows any device or another method to control the spider bushing clearance without the removal of the spider cap.
