Product Description

HPC Primary Crusher
HPC Primary Impactor

The HPC Primary Compound Impact Crusher is ideally suited for crushing medium-hard rock down to a well graded product size of 0 – 2 inch. With its unique double rotor design, very high material reduction ratio and its proven operational benefits, this compound crusher is widely utilized within cement plants where raw grinding is performed by ball mills.

Housing System
Housing System

The primary crusher housing is a rugged, fabricated steel plate construction with heavy external bracing for increased strength. For quick and easy inspection of the internal wear parts, the housing is fitted with large doors which are secured/ opened by a special dovetail locking mechanism. The HPI is also equipped with a service platform for easy and safe accessibility to its roof area. The rear housing section opens hydraulically, permitting complete access to the internal wear parts. With emphasis on safety, the weight of the housing (open position) is transferred over center preventing it from closing on its own.

Liner System
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 80%. 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.

Apron System
Front Apron

The Front Apron (primary impact zone) is an extra heavy duty, fabricated component that is utilized for the initial flow control & reduction of the feed material. In its lower wear zone, the apron is fitted with a bolt-on, 3 inch thick wear-resistant impact liner. With simplicity and function in mind, these liners have been standardized to a common shape; interchangeable with the rear apron liners.

Rear Aprons

The Rear Aprons (second and Third impact zones) is a heavy duty, fabricated component that is utilized for the secondary flow control & reduction of the feed material. In its lower wear zone, the apron is fitted with a bolt-on, 3 inch thick wear-resistant impact liner. With simplicity and function in mind, these liners have been standardized to a common shape; interchangeable with the front apron liners.

Third Crushing Path
Third Crushing Path (Patented Design)

The third crushing path is designed as a series of impact steps, which provide an excellent level of control and consistency over the product grading. Each step is fitted with interchangeable, high chrome, replaceable wear caps. The patented design of the third crushing path is found in its unique, but highly advanced retraction system. When needed, the third crushing path reacts and retracts out of its working position, thus helping to eliminate potential damage, unscheduled downtime and excellent tramp iron control.

GSK Rotor

The success of the HAZEMAG GSK rotor can be found around the world. Its massive construction, combined with its smart and fully functional design, has resulted in a primary rotor system that delivers positive and beneficial results on every level. Its blowbars, offering a utilization factor of 50%, are secured into place by means of a massive backing bar and wedge. The forward profile design of the blowbar delivers excellent and consistent gradation results throughout the lifetime of its wearing zone.

HAZtronic System
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!


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.
