During the operation of the machine, the fastening of the bolt and nut can become loosened due to vibration, heat, etc. To prevent this, a washer is normally used before tightening the nut and locking it with a split pin after tightening. Spring washers and the use of two nuts tightened in opposite directions are some other methods of locking.

The crusher is easy to adjust, and, in common with most machines of the jaw type, is a simple crusher to maintain. As rock particles are compressed between the inclined faces of the mantle and concaves there is a tendency for them to slip upward. Slippage occurs in all crushers, even in ideal conditions. Only the particle’s weight and the

The HYDRAULIC CONE MOUNT is a combination of a spring component and a hydraulic shock absorber in the shape of a cone. With this both components can be tuned to each other. For good vibration insulation you need a low dampening coefficient but for movement control you need a high dampening coefficient.
