Cone crusher with fabricated upper and lower main frames - has anti-spin mechanism allowing mantle to rotate only in one direction unless excess force is applied

摘要

The cone crusher has a fabricated frame, an anti-spin mechanism and crusher setting indicator. The frame, includes a number of tubular members, a number of annular members and a number of ribs, all of which are welded together to provide a rigid, strong frame. The anti-spin mechanism comprises a unidirectional valve and a spring loaded ball valve, permitting the rotation of the mantle of the crusher in one direction while barring rotation of the mantle in the opposite direction unless a force exceeding a pre-selected magnitude is applied to the mantle. The crusher setting indicator, includes a rod supported by the crusher, the rod abutting the cone support bearing seat of the crusher, the position of which seat is directly related to the position of the mantle.
