CONE CRUSHERS

GRAU Cone Crushers are based on Roller Bearing System which makes them superior compared to cone crushers with bronze hydrostatic bearing. All cone crushers are equipped with dynamic closed side setting system.

CONE CRUSHERS

ROLLER BEARING TYPE DESIGN

GRAU technological bearing system allows the cone crushers to operate at higher RPMs. High RPM combined with aggressive eccentric stroke and wide-angle crushing chamber ensure optimum capacity and cubical product. High reduction ratio is obtained especially in secondary applications.

 

FRICTIONLESS LABYRYNTH SEAL SYSTEM

Each section of GRAU Cone Crushers has been designed and manufactured for durability. Frictionless labyrinth seal system offers great protection for the main bearing shell against dust. It allows the cone crusher to run cooler and requires less oil. Therefore, less motor power is wasted on friction and cooling.

 

HYDRAULIC ANTI-SPIN SYSTEM

GRAU Cone Crushers are equipped with Hydraulic Anti-Spin System. The system prevents the head from spinning when running with intermittent feed. The cone crusher requires no additional resetting or maintenance and is designed to work out of the box.

    SUPERIOR ROLLER BEARING DESIGN
    GRAU Cone Crushers are based on Roller Bearing System which makes them superior compared to cone crushers with bronze hydrostatic bearing. Since GRAU Cone Crushers do not have upper bearings, their inlets are completely open. This enables homogenous feeding into crushing chamber in coarse feeding applications.
  • EXCEPTIONAL HYDRAULIC PROTECTION
    Hydraulic pistons around the cone crusher body provide protection against metal and other non-crushable parts that may be present in the feed material. These pistons lift and separate the upper body from the lower body. The hydraulic system is equipped with sensors that sense the excess load and lift the upper body until the metal part passes through. The system works separately from the machine settings and does not change the CSS values. The same pistons can be used for cleaning of the material in case of electric failure during operation.

    DYNAMIC CLOSED SIDE SETTING
    GRAU Cone Crushers are equipped with dynamic setting system which allows to adjust the CSS during the operation and from remote locations. This system is powered by a hydraulic power unit that rotates the mantle on a thread and changes the distance between the bowl and the mantle. The system operates by a single press of a button and helps with fine adjustments in order to minimize the abrasion effects. Thanks to its rapid releasing option, the same mechanism enables rapid removal of bowl housing without removing the upper body. The same system also utilizes a hydraulic locking mechanism that fixes the setting values.
PRODUCT HIGHLIGHTS
GRAU Cone Crushers operate on rubber buffers that minimize the vibrations on the chassis both horizontal and vertical.
Hydraulic Self-Adjusting Motor Base
This system automatically adjusts the belt tension that may have changed in different weather condition and ambient temperatures.
