Jaw Gyratory Crusher Pro – next gen underground crushing
In primary crushing operations, your crusher needs to be able to deal with everything that’s thrown in it – including the big stuff. With an enlarged feed opening, the Jaw Gyratory Crusher Pro is the ideal solution for underground and block cave mining applications. No material too coarse, no chunks too large.
What we offer
All the benefits of a gyratory crusher – with the largest feed opening
The Jaw Gyratory Crusher Pro is engineered to handle bigger chunks of material than comparable gyratory crushers of the same mantle diameter. This gives you greater flexibility in your crushing operation, and reduces the tendency for bridging in the feed zone. Despite being capable of handling large feed materials, the Jaw Gyratory Crusher Pro still delivers a fine and uniform product thanks to its higher crushing ratio.
The main characteristic of our jaw gyratory crushers is their enlarged feed opening, which is located on one side of the crusher only. It is normally serrated and, together with the upper part of the mantle, it forms the initial crushing zone. The coarsely crushed material is then reduced to the desired product size in the crushing chamber below.
The Jaw Gyratory Crusher Pro combines all the advantages of a common gyratory crusher, including:
- Hydraulic adjustment of crushing gap to compensate for wear
- Hydraulic main shaft adjustment for overload protection
- Gyramatic monitoring and control system
- Direct drive via disc-pack coupling with floating shaft and safety coupling
- Cyclo-palloid spiral bevel gear for smooth operation and use of high-capacity drive motors
- High starting torque allows start of crusher under load (in emergencies)
Key benefits
A mining primary jaw gyratory crusher for large, coarse materials
The main benefit of the Jaw Gyratory Crusher Pro is its ability to crush bigger chunks of material at high throughput rates – without succumbing to blockages and bridging. What’s more, maintenance is easy by design, so you can keep downtime to a minimum.
- Enlarged feed opening can handle large chunks of material without bridging
- The enlarged feed opening ensures this primary crusher can manage all the materials coming from your mine without an issue. Reduced bridging. Reduced downtime.
- High throughput rates above 4000 tph
- The Jaw Gyratory Crusher BK 63-75 Pro is designed for capacities above 4000 tph, giving you the productivity you need.
- Maintenance-friendly design
- The Jaw Gyratory Crusher Pro is designed with easy access to all heavy components from above, so no one has to be underneath the crusher to carry out maintenance work. The machine is also designed for optimum strength and low wear, so maintenance is kept to a minimum.
- Adaptable for increased safety and performance
-
The flexibility of this machine ensures we can customise your crusher to meet the specific needs of your application.
There are several options to increase safety and performance, including:
- Double mouth spider with hydraulic spider fixing unit
- Spherical spider bearing
- Eccentric removal trolley
- Concave mounting rack
- Concave dismantling device (concave pans)
- Main shaft stand
- Hydraulic nuts
- Enclosure of hydraulic unit, comparable to IP 54
- Different liner configurations etc.
Product features
An impressive high-performance crusher
When it comes to primary crushing, any loss in performance has the potential to become a bottleneck within your process. The Jaw Gyratory Crusher Pro is designed to withstand the harsh environment of an underground or block cave mine, while still offering pro performance and optimum safety.
The Jaw Gyratory Crusher Pro combines all the advantages of a common gyratory crusher, including:
- Hydraulic adjustment of crushing gap to compensate for wear
- Hydraulic main shaft adjustment for overload protection
- Gyramatic monitoring and control system
- Direct drive via disc-pack coupling with floating shaft and safety coupling
- Cyclo-palloid spiral bevel gear for smooth operation and use of high-capacity drive motors
- High starting torque allows start of crusher under load (in emergencies)
The optimised crushing chamber with huge feed opening also ensures you benefit from:
- High throughput rates
- Less tendency of bridging
- High crushing ratio
- Two crushing stages
- More fine and uniform product
- Low operating and wear costs
Crusher drives
Our gyratory crushers are typically driven directly via a disc-pack coupling with a floating shaft and a safety coupling.
The disc-pack coupling compensates for geometric misalignments between the motor shaft and the countershaft, while the safety coupling protects the crusher motor from overload when uncrushable tramp material enters the crusher. The floating shaft allows the countershaft to be removed without having to remove the motor.
The “Gyramatic” monitoring and control system for our gyratory crushers ensures easy, safe operation of these crushers in a range of applications. This compact, robust unit consists of a control cabinet with a touch screen terminal. The terminal can be used interactively to input set points and read off operating data.
Services
Whenever you need us, our maintenance and repair crews are on hand to help, from specialist advice, inspections and modifications through modernisations and performance enhancement, to damage analyses and repairs, which are performed exclusively by our highly qualified assembly personnel using high-quality, certified spare parts.
If necessary, we will maintain and repair your crusher at one of our service centers. You can call on these services not only for crushers from our own production lines, but also for machines manufactured by other suppliers.
