Abstract
A screw adjust cone crusher with a top tramp iron relief system where the bonnet can be vertically adjusted by rotating the threaded bonnet support within the threaded lower section. The tramp iron system is disposed entirely above the bonnet, thereby creating a small footprint screw adjust cone crusher with overhead tramp iron release system.
Claims16
A system for crushing rock comprising:
- a lower section generally comprising a container with a top side opening with internal threads disposed inside a circumference of the top side opening;
- a gyrating cone coupled to said lower section;
- an upper section comprising:
- a bonnet support comprising external threads configured to mate with said internal threads;
- a bonnet disposed on said bonnet support, said bonnet configured to resist movement of rock caused by collision of rock with said gyrating cone;
- a tramp iron relief system comprising:
- a plurality of accumulators disposed above said bonnet.
4 more elements
A cone crusher comprising:
- a gyrating cone;
- means for supporting the gyrating cone;
- a bonnet;
- means for supporting said bonnet, such that rotation of an external ring gear rotationally coupled with said bonnet results in rotation and up and down movement of the bonnet, depending on a direction of rotation of the ring gear;
- and,
- means disposed substantially entirely above the bonnet, for releasing tramp iron from under the bonnet.
3 more elements
A cone crusher comprising:
- a gyrating cone;
- a bonnet, disposed above said gyrating cone;
- means for maintaining an adjustable vertical separation distance between said bonnet and said gyrating cone, where adjustment of the adjustable vertical separation distance is achieved by rotating two threaded objects with respect to each other in one direction to achieve an increased adjustable vertical separation distance and in an opposing direction to achieve a decreased adjustable vertical separation distance;
- and
- means, disposed substantially entirely above the bonnet, for releasing tramp iron from under the bonnet.
