The new Nordberg® HP450e™ cone crusher provides better performance and uptime in a more sustainable way. It offers enhanced performance, easier and safer maintenance, and a series of other improvements, making it the perfect choice for aggregate and mining operations.
- New enhanced kinematics and more efficient chambers.
- Up to +10% performance in Secondary and Tertiary application (compared to HP400).
- +10% more head motion.
- +13% more power (in kW and HP)
- +20% more force.
- No-backing liners for quick, easier and safer liner change.
- Head spin brake extends liner wear life.
- Enhanced tramp release cylinder mounting.
- New feed cone lifting tool, for safe lifting and handling.
- Three alternative kinematics to choose from.
- Alternative speeds.
- Enhanced chamber designs and application specific chambers.
- Exceptionally wide chamber offering.
Enhanced performance
Evolution in performance is achieved by four factors: kinematics, chambers, release force and power rating. New HP450e crusher’s performance is up to +10% (compared to traditional HP400 crusher) when used in secondary application and in tertiary application.
Tune the HP450e crusher into the wanted application by choosing the optimal kinematics. There are three alternative kinematics to choose from.
- Enhanced kinematics for maximum performance in terms of capacity and reduction.
- Classic HP400 kinematics for conventional HP400 performance. This is to reach the same performance level as before with the HP400 crusher. When aiming at exactly to the same performance as with HP400 before, in terms of throughput and reduction, and when maximizing part similarity in the machine.
- Reduced stroke for reduced throughput. To be used when further limiting throughput for rest of the circuit, when tuning the crusher into a specific application, or when limiting power and force.
Improved uptime and serviceability
HP450e cone crushers are fitted originally with no-backing manganese (mantle and bowl liner). This saves time in liner replacement as no time is needed for backing compound solidification.
Logistics is easier as there is no need to source, store and transport backing compound.
Liner installation process becomes much safer as there is no need to handle, mix and pour the backing material. Solution is environmentally friendly as backing material is not needed.
Specific feed cone lifting tool provides further safety improvement, it is designed specifically for safe lifting and handling of the feed cone. Further developed tramp release cylinders are made easier to remove and re-install for easier service and maintenance of the equipment.
Extended lined lifetime thanks to the head spin brake, which slows down head spin on idle. Optional ring bounce monitoring enhances machine protection.
Great parts compatibility between crusher generations
Majority of the spare and wear parts of the new HP450e and the HP400 cone crusher are compatible enabling economical, operational and environmental benefits for mixed fleet operations. With the bowl and head upgrade kit, the new no-backing liners can be installed in the HP400 cone crusher. Classic HP400 liners with backing material can be used in the HP450e crushers alternatively, too.
Wider application coverage
New application specific chambers:
- Coarse chambers EC (Extra Coarse) and C (Coarse) for the most efficient secondary crushing
- Fine end chambers for tertiary and fine crushing
- F-NF (Narrow Fraction) to maximize yield of typical aggregates fractions (for example 5-8mm / ¼” x 3/16”, 8-11 mm / ½” x ¼”)
