| 摘要 |
Apparatus is disclosed for controlling the outlet gap of a cone crusher, comprising a detecting core disposed within a main shaft of the cone crusher and a plurality of coils fixedly disposed with respect to the detecting core and forming therewith a differential transformer. A suitable electrical circuit is associated with the differential transformer to develop an electrical signal to be applied to a suitable measuring means such as a meter for providing an indication of the size of the outlet gap. In an illustrative embodiment of this invention, the measuring means is adapted to control the vertical movement of the main shaft of the cone crusher to adjust the outlet gap, thus enabling minerals to be crushed to a predetermined size.
