HPI-H | PRIMARY IMPACTOR

Liner System

With simplicity and function in mind, the housing is fitted with 1¼ inch thick, interchangeable, wear-resistant liners that have been designed as a common shape. The liners have an interchangeability level of approximately 95%. A further benefit with this liner design is realized in the form of increased wear metal utilization. A worn liner, for example, can be repositioned from a high wear zone (within the rotor circle), to a low wear zone (outside the rotor circle), thus extending its service life. The standardized design of the housing liner system helps to further reduce the impactor cost of operation. 

Monoblock Apron

The Monoblock Front apron (primary impact zone) is designed and cast as a massive, single piece manganese component. In primary crushing applications such as the processing of shot rock limestone, the monoblock apron is fitted (bottom impact zone) with a heavy duty, replaceable wear resistant liner. Due to its massive weight and increased impact / wearing zone, the design of the monoblock apron provides a level of improved benefits such as: reduced stress to the housing system, increased service life, increased control over the product size, reduced downtime / maintenance and reduced operating costs. Depending on the application and characteristics of the feed material, such as concrete with steel, the monoblock apron can also be supplied without the lower wear liner. 

Rear Apron, Rear Wall and Inlet Section – Multiblock System

The rear apron (secondary impact zone) has been designed and cast as a single piece, manganese multiblock (interchangeable system) component. For extended service life, reduced operating costs and increased product size control, the rear apron multiblock is fitted (lower section) with a heavy duty, wear resistant replaceable liner. With simplicity and function in mind, the rear apron multiblock (movable), rear wall multiblock (fixed) and inlet section multiblock (hydraulically movable) are interchangeable. 

Third Crushing Path (Patented Design)

The third crushing path (grinding path) is found in our HPI-H Third Crushing Path line of primary impactors. The third crushing path is designed as a series of impact steps (or ledges) which provide an excellent level of control over the product grading, enhanced product soundness and very high cubical product shape. The third crushing path can be adjusted (top & bottom settings) through external hydraulic cylinders.

HAZtronic system

The exclusive and unique computer-controlled hydraulic adjustment system for the impact aprons (and third crushing path) allows for quick gap adjustments, optimum control over the product size, smoother crusher operation, tramp iron protection, reduced downtime and reduced operating costs. In our technically advanced HAZtronic system, the impactor performance can be optimized with recipes or pre-programmed apron settings, which further enhance the quality and consistency of the product. The HAZtronic system also allows you to optimize the correct apron settings with the varying material characteristics within the quarry. When fitted with either system, the impactor achieves a level of performance and economical operation that remains second to none. You are in control – producing the products you sell the most!

OPERATION, ADJUSTMENT AND CONTROL

With simplicity and function in mind, optimizing the performance of the HPI impact crusher is enhanced by a touch screen control panel. Opening the impactor housing and adjusting the impact aprons is performed at the touch of a button. This system also monitors and visually displays the apron positions, bearing temperatures, hydraulic fluid temperatures and hydraulic fluid levels.
