摘要

PCT No. PCT/EP86/00519 Sec. 371 Date May 11, 1987 Sec. 102(e) Date May 11, 1987 PCT Filed Sep. 9, 1986 PCT Pub. No. WO87/01305 PCT Pub. Date Mar. 12, 1987.A method and apparatus for adjusting the gap width between a rotatable crusher cone and a crusher housing includes determining a reference position of the crusher cone relative to the crusher housing, storing a first quantity representative of the reference position, rotating the crusher cone, moving the crusher cone to the reference position, moving the crusher cone from the reference position toward the crusher housing until a limit is reached and measuring the distance of the crusher cone from the reference position, storing a second quantity representative of the distance, repeating the preceding three steps a plurality of times while separately storing each of the second quantities, obtaining a new reference position based on each of the second quantities, and determining an operating position of the cone crusher based on the new reference position. The apparatus includes a control device, a memory, a position detecting device for detecting the position of the crusher cone, and an apparatus for detecting whether the crusher cone is moving.
