Nordberg HP4 and HP5 Cone Crushers from Metso

The Nordberg HP5 follows the successful HP4 as the second model of an all-new range of high-performance cone crushers, benefiting from the

very latest in Metso crushing technology. Its heavy duty design derives from our 70+ years of experience with the Symons cone crusher, known worldwide for its rugged construction and application versatility. Labor-saving features such as hydraulic setting adjustment, tramp release and cavity clearing recall the innovative Nordberg Omnicone and first generation of Nordberg HP crushers. The HP4 and HP5 achieve new heights with unique features that produce the highest reduction ratios, ease of operation and low maintenance requirements.
Highest performance
The HP4 and HP5 cone crusher enable you to produce much finer products with fewer crushing stages, thereby lowering costs and saving energy. With a combination of optimized speed and large throw, HP4 and HP5 provide the highest reduction ratios of any current cone crusher. Due to their highly efficient crushing action, the HP4 and HP5 have high power utilization per cone diameter. As a result, you save twice with lower energy costs per ton of crushed end product and with lower recirculation load.

Higher cavity density improves crushing action for end products with more consistent gradation and superior shape. The new crushers maintain the proven threaded rotating bowl design. Comparative tests show equalized wear and more consistent setting around the entire circumference of the crushing chamber. Also the use of a newly designed tramp release system, with fixed return point, ensures that the crusher setting is maintained even after passing a piece of tramp iron.

Less downtime
Another way the crushers deliver is less downtime and increased operator confidence. Dual-acting hydraulic tramp release cylinders let the HP4 and HP5 pass tramp iron that would stall, or damage, many other crushers. If the jaw crushers does stop under load, the dual-acting cylinders provide a large clearing stroke, independent of liner wear, to quickly clear the crushing cavity.

An advanced fastening system for the mantle and bowl liner makes backing material unnecessary, and makes liner changes faster. When liners are changed or the crusher is reconfigured, the same hydraulic motors that rotate the bowl for setting adjustment will rotate the bowl completely out of the adjustment ring threads, greatly simplifying liner replacement. A new fixed counterweight guard protects the counterweight and seals out dust.
Easy to maintain
Bronze bushings used throughout provide superior load capability in the dusty, high-shock crushing environment. They cost less than rolling element bearings and are easy to replace in the field with normal tools. The HP4 and HP5 are easy to disassemble. All components are accessible from the top or side. The bowl and head are easily removed with no interference fit.

Versatility
Due to their strength, speed range and ease of converting from coarse to extra fine applications, the HP4 and HP5 provide superior application flexibility.

• Save stockpile space by re-crushing excess or slow moving products without an intermediate crushing stage.
• Converting from coarse to extra fine application and back again just by changing liners and rpm.
• Liner and rpm combinations go from secondary applications to sand manufacturing.

Asset Protection
The new tramp release design also protects the main frame by smoothing out the impact forces and returning the bowl to its original position after passing tramp iron. Inside, a new fixed guard protects counterweight and seals out dust. An optional cover around the crusher protects employees from casual contact with adjustment and tramp release mechanisms. It also helps protect the workplace with reduced dust emissions. The environment benefits too from the advanced fastening system for mantle and bowl liner that do not require backing material.
