Definitions
- Quarried material is often processed by means of crashing plant, for the production of aggregate, for example.
- crashing plant for the production of aggregate, for example.
- a jaw crusher There are various known forms of crashing plant for the comminution of rock material and the like, one of which is referred to as a jaw crusher.
- One conventional j aw crasher consists of a frame having side walls and a pair of j aws, a fixed j aw and a swing j aw, disposed therebetween.
- the fixed j aw and a swing j aw each have a crashing face, the crashing faces being arranged in a spaced apart relationship to define a crashing chamber for receiving material to be crashed.
- the swing j aw is movable between a first position in which the crushing face of the swing j aw is inclined to the crashing face of the fixed jaw, and a second position in which the crashing face of the swing j aw is brought substantially parallel to the crashing face of the fixed jaw, at a predetermined spacing therefrom.
- the predetermined value is greater than zero and may be between 300 and 500 bar.
- the cylinders are mounted in the apertures in the walls, the load from the cylinders is transferred directly on to, and in line with, the walls, which greatly reduces the stresses within the crusher frame for any given weight of stracture.
- This enables a substantially compact design of j aw crusher, which has particular advantage for use on a mobile crasher plant.
- the mobile chassis can be significantly narrower than is conventionally required, thus reducing the weight of the plant and increasing the movability of the plant.
- a toggle plate 54 is provided between the rear face of the swing j aw 18 and the cross beam 42, respective ends of the toggle plate 54 being movably received in a toggle seat 56 provided on each of the cross beam 42 and the swing jaw 18, for communication therewith.
- the toggle seats 56 have an arcuate internal profile against which the respective ends of the toggle plate 54 are in contact.
- the ends of the toggle plate 54 each have an arcuate profile which is shallower than that of the toggle seats 56, the toggle plate 54 thereby being able to self-centre in the toggle seats 56.
- Material to be crushed is introduced into the crashing chamber 26 through the top of the jaw crasher assembly 10 and crashed material is discharged through the spacing between the lower end of the two jaws 16, 18.
- the cyclic movement of the swing jaw 18, as described above, causes impelling forces for crushing the material present in the crushing chamber 26.
