JAW RETENTION fixed and moving jaws are retained with a wedge locking system. The main frame and swing jaw holder are protected from wear due to the unique design of the jaw faces that protect the inlet and outlet points of the crushing chamber. Wedges actuate from the side of the crusher for easy installation and maintenance.
In the jaw crusher, the ore is crushed and reduced to the required particle size. When the moving plate moves away from the fixed plate, the ore is sliding down freely from the upper portion of the crushing chamber to the discharge port under the action of gravity.
Most crushers employ a combination of all these crushing methods. Impact Impact refers to the sharp, instantaneous collision of one moving object against another. During the collision, both the objects may be moving, such as a cricket bat hitting a fast moving ball, or only one object may be moving, such as a rock being struck by hammer blows.
With jaw crushers, if you allow the jaw dies to move during operation they can cause damage to the frame of the jaw crusher. Similarly, loose liners in cone crushers may damage the head or bowl.quot; It is also advisable that operators frequently look for holes, cracks, or flat spots, which could potentially damage the machine long term or be an ...
The finite element analysis software ANSYS was used in the numerical simulation of the frame of CJ411 jaw crusher and the main causes leading to the frame crack were analyzed. The accidental load led to the evolution of the defects in the casting member of the crusher that was under high stress, leading to the flaws.
Jaw Crushers are sized by the top opening of the crushing chamber. For example, a 32 x 54 Jaw Crusher measures 32quot; from jaw die to jaw die at the top opening or gape opening and 54 across the width of the two jaw dies. The narrower bottom opening of the crushing chamber is used to size the discharge material.
