Jaw crusher is widely used in crushing field, because of its simple structure, reliable performance, and easy maintenance.
The moving jaw of single toggle jaw crusher is hanging in the eccentric shaft directly to connect rod without separating connecting rod.
Since the movable jaw is directly driven by the eccentric shaft of the eccentric, so the active jaw may also do the vertical and horizontal complex swinging.
Swing trajectory of each point in Hubei board is close to a circle by the top of the continuous change to the lower part of the oval, and the more oval to the lower flat.
Horizontal stroke moving jaw grows from the bottom up changing, but also plays the role of crushing stones not only from the crushing, but also chipping.
The steering direction of eccentric shaft is counterclockwise, and the direction of motion of each point on the movable jaw is conducive to promoting nesting, so it has a high crushing efficiency, a higher rate, even granularity which are mostly cubical shape.
Compared to simple jaw crusher, the single toggle jaw crusher is lighter with a simpler structure and higher working efficiency.
But the vertical movement of single toggle jaw crusher is longer, so the wearing of jaw plate is more serious. So more energy will be consumed and more dust will be produced.
The single toggle jaw crusher is mainly composed of the rack, jaw, side guard plate, spindle, flywheel, toggle plate and adjusting mechanism.
The body of the crusher is its base which is a Quartet bucket with the upper and lower openings.
It is used primarily for supporting the eccentric shaft and withstand the reaction force of the broken materials, and therefore required to have sufficient strength.
The segments of large crushers are cast separately, and then bolt assembly together.
The casting process is more complicated.
Homemade small jaw crusher can be welded with 40 to 50 mm thick steel plate, but its strength is not so good as cast.
