Nordberg HP (High Performance) Series cone crushers feature a unique combination of crusher speed, throw, and cavity design. This combination has proved revolutionary in providing higher capacity and superior product quality, and in providing a wider range of application suitability. From limestone to taconite, from ballast production to manufactured sand, and from small portable plants, HP cone crushers provide unbeatable performance in secondary, tertiary, and quaternary applications.
A history of quality
Nordberg HP cone crushers are built on the success of our 70+ years of CS cone experience, and 20+ years of Nordberg Omnicone experience. The CS cone is well known for its rugged construction and application versatility. The CS cone has set the standard in the mining industry, where 24-hour, high-reduction applications can destroy all but the most ruggedly built machine.
The Nordberg Omnicone introduced many new innovations to reduce maintenance and operating costs, and to provide designed-in modern features such as hydraulic setting adjustment, tramp release, and cavity clearing. The field-proven HP series combines the best of these technologies to provide the highest capacity, the best product shape, the highest on-spec yield, easy automation, and the greatest possible reliability and flexibility. All to help you achieve the highest possible levels of profitability.
Reach New Heights with Metso
Higher capacity: Thanks to the patented combination of higher speed and throw, which increases the machine’s power rating and throughput capability, HP Series cone crushers have the highest capacities for their size in the industry.
HP technology allows you to use either fewer or smaller units to get the highest possible production out of the smallest possible space. Metso pioneered the HP technology, having developed it in 1989 through extensive pilot and full-size prototype testing. Metso has been awarded patents for these innovative efforts.
Higher quality: The unique interparticle crushing action of HP Series cone crushers creates a higher value for your product by providing a more consistent gradation and a superior product shape (cubicity). The ability to operate at a fixed mechanical setting – instead of the head floating on a column of hydraulic oil – creates less setting drift and provides more stability throughout the circuit.
The proven benefit of a threaded rotating bowl maintains a consistent setting around the entire circumference of the crushing chamber. Also, the use of a tramp release system with a fixed return point makes sure that the crusher setting is instantaneously maintained even after passing a piece of tramp iron. HP Series cone crushers also enable you to produce a finer product with fewer crushing stages, lowering your capital costs and saving energy.
Higher yield: By operating the HP cone crusher on the lower end of its speed range, the product gradation can be shifted to produce fewer fines and a higher percentage of on-spec product. The HP cone crusher creates a higher value product with less waste.
Features and Benefits
Less downtime: Dual-acting hydraulic tramp release cylinders mean the HP cone crushers can pass tramp iron that would stall many competitors’ crushers.The large clearing stroke indepen-dent of liner wear reduces the effort required to clear a stalled crusher, reducing downtime and increasing operator confidence.
Hydraulic motors rotate the bowl for fine control setting adjustments that also rotate the bowl completely out of the adjustment ring threads for liner changeout, greatly simplifying liner change. Advanced liner retention technology increase reliability: Bowl retaining wedges engage a self-tightening helix on the upper section of the bowl liner, while a selftightening lock-bolt retains the mantle.
Easy to maintain: Bronze bushings used throughout provide superior load capability in the high-shock, dusty crushing environment. They’re lowcost, and easy to replace in the field with normal tools. HP cone crushers are easy to disassemble. All components are accessible from the top or the side. The head and bowl can be removed without upsetting a bolted interference fit.
Low maintenance costs: High performance non-contacting labyrinth seals provide high reliability by keeping out dust without wearing out. Their simple design means fewer moving parts come into contact with the rock and dust.
Excellent wear protection of all crusher components – including replaceable head ball, mainframe seat liners, mainframe pin bushings, countershaft box frame ring, counterweight guard, mainframe liners, and the dead-bed feed hopper – keep maintenance costs to a minimum.
Application flexibility: HP cone crushers can be converted from the finest to the coarsest cavity simply by replacing the mantle, bowl liner, adapter ring, and wedge bolts. Easy to operate Using the hydraulic motor setting adjustment with the adjustment under load capability makes it easy to balance the crushing circuit and optimize crusher productivity.
The addition of a hydraulic motor position transducer system to keep track of crusher setting is all that’s required to connect the crusher to a plant DCS system for full automation applications.
Cone Crusher Capacities
Cone crusher capacity charts are developed for use as an application tool to properly utilize the HP crusher’s capabilities. The capacity figures shown apply to material weighing 100 pounds per cubic foot or 1600 kg per cubic meter. The crusher is one component of the circuit. As such, its performance is in part dependent on the proper selection and operation of feeders, conveyors, screens, supporting structure, electric motors, drive component and surge bins. Where used, attention to the following factors will enhance crusher capacity and performance.
1. Proper selection of crushing chamber for material to be crushed.
2. A feed grading containing proper distribution of the particle size.
3. Controlled feed rate.
4. Proper feed distribution 360° around crushing chamber.
5. Discharge conveyor sized to carry maximum crusher capacity.
6. Properly sized scalping and closed circuit screens.
7. Automation controls.
8. Adequate crusher discharge area.
