CONICAL CRUSHER WITH STRUCTURE FOR MEASUREMENT OF POSITION OF CRUSHING HOUSING Russian patent published in 2015 - IPC B02C2/04 B02C25/00 

FIELD: mining.

SUBSTANCE: crusher contains external (22) and internal (28) crushing housings with the discharge slot (30) between them. The element (14) of the top frame supports the external housing in engagement with the element (16) of the lower frame. The engagement is implemented with a possibility of regulation of vertical position of the external housing with reference to the element of the lower frame to provide regulation of width of the discharge slot. The structure (64) of the sensor is fitted with the sensor element (72) on one of elements of the lower frame and the top frame for measurement of vertical position of the external housing. One of indicator devices (76, 80, 70) and the sensor element (72) are implemented with a possibility of following the vertical movement of the element of the top frame and movement one with reference to another. The sensor element contains the vertical sensitive array (74) in the vertical direction, lengthways, at least, of the range section. The indicator device can move at regulation of vertical position of the element of the top frame within the range section. The indicator device is implemented with a possibility of detection in various vertical positions along the vertical sensitive array.

EFFECT: invention improves the accuracy of measurement of vertical position of the adjustable crashing housing.
