Jaw crusher mode-of operation and special characteristics

jaw crusher 

 

mode of operation:

Jaw crushers are equipped with one fixed and onemoveable crushing jaw (moving jaw), both of whichsupport crushing plates (wearing parts) in severalversions. They form a wedge-shaped crushing zone.The walls of the crushing zone are made of replace-able wearing sheets. Crushing is done between thetwo crushing jaws. The moving jaw of the singletoggle jaw crusher moves elliptically. A pendulummotion is being carried out by the double togglejaw crusher.

The crushing force is produced by an eccentricshaft. Then it is transferred to the crushing zone viaa toggle plate system and supported by the backwall of the housing of the machine. Spring pullingrods keep the whole system in a condition of non-positive connection. Centrifugal masses on theeccentric shaft serve as compensation for heavyloads. A flywheel is provided in the form of a pul-ley.

Due to the favourable angle of dip between the crushing jaws, the feeding material can be reduceddirectly after entering the machine. The final grainsize distribution is influenced by both, the adjusta-ble crusher setting and the suitability of the toothform selected for the crushing plates.
special characteristics:

An adjustable wedge system makes infinite adjust-ments of the crusher setting possible. The systems,spindles exert a direct influence on the thrust-bear-ing trestle. All parts of the adjusting system areaccessible, maintenance-free and easy to replace. All of the toggle plates are provided with replace-able tempered pressure bars on both sides, whichwork according to the move on rolling contact prin-ciple. They are maintenance-free. A lubricationsystem ensures sufficient grease supply to all other bearing points.
