GH-HP400RFSD Portable Plant

Nordberg HP400 Cone Crusher, The heart of the plant is the high performance HP Series cone crusher. Designed for portable installations, this cone crusher is the most compact, economical to operate and productive machine in its class. The HP Series offers substantially higher production capacity over traditional cone crushers. It also provides excellent product shape, making it suitable for both secondary and tertiary crushing.

Equipped with manganese steel crushing members, bronze bearings and replaceable main frame seat liners. Features include hydraulic bowl clamping and adjustment, automatic tramp iron release and hydraulic clearing of the crusher chamber. Remote control station mounted to side of plant allows convenient operation for adjusting the closed side setting, or for clearing the crusher.

Additional HP cone features include a package lubrication system consisting of an internal independent pump, oil pressure switch, temperature switch, oil tank with strainer, oil level gauge, thermometers at three locations, (2) oil heater with control panel, oil filter and oil cooler (air-radiator type), and crusher tools.


400 HP Crusher Drive Motor, 1800 RPM, 460 Volt, 3 Phase, 60 Hz, TEFC Crusher Duty, including motor platform with hydraulic slide motor base.  Motor guard with removable panel for easy sheave changes.

The Crusher Feed Basket is a weldment which sits over the feed opening, it directs material into the crusher feed opening and reduces spillage. The feed basket is made of 1/4" mild steel with a 3/8" base plate. Windows allow the operator to view the material level in the feed basket. The feed basket may need to be removed for highway towing.

The Overflow Chute is a steel trough that bolts to the side of the crusher feed basket. When an overflow condition occurs, the excess is directed to a discharge conveyor, bypassing the crusher. The chute is 17" wide and constructed from 1/4" mild steel. Because overflows should be rare occurrences, AR liners are not required or provided.

The Feed Basket Overflow confines the material to the crusher feed opening.  Overflow material is directed to the discharge conveyor.
