Features of the mobile jaw crusher
Hydrostatic drive:
Highly efficient hydraulic drive in both directions of rotation of the crushing unit. Thanks to the hydrostatic drive, one obtains a flatter load graph of the diesel engine despite the high load peaks in the crushing chamber, resulting in lower fuel consumption and longer life of the drive components.
Ultrasonic level measurement in the crushing chamber.
The level of the feed material is continuously measured by means of an ultrasonic sensor which proportionally controls the feed hopper to automatically level the set working height in the crushing chamber. This ensures maximum efficiency of the machine and ensures that the crushing chamber does not run empty regardless of the hardness of the material to be crushed.
Automatic toggle.
By means of a hydraulic cylinder arranged vertically on the moving jaw, the dropout opening is adjusted. This also ensures that, in the event of an overload or an unbreakable part that may be in the material being processed, it retracts the moving jaw and discharges the crushing chamber.
CSS position control:
After this action, the hydraulic cylinder automatically resets to its set value. In order to obtain as uniform a product as possible, this setting is continuously monitored during operation and, if necessary, adjusted on the central control panel. All functions and set values are clearly arranged via a screen on the central control panel of the machine.
The wear parts:
The moving and fixed jaw, are interchangeable and separately reversible.
Discharge belt:
With a length of 13500 mm as a standard design provides a large storage capacity. This conveyor can move up and down hydraulically and is quickly dismountable for easy maintenance.
Power source:
CAT C9 ACERT 350 HP (261Kw) engine in a spacious engine compartment easily accessible all around and an innovative hydraulic system provides major improvements for the benefit of fuel consumption.
