Belt-compatible crushing of large material volumes – directly at the extraction point
The Horizontal Impact Crusher HHI by HAZEMAG is a compact, complete primary crushing plant for crushing medium-hard rock, coal and recycling material with a high degree of size reduction. It was developed for applications where material needs to be picked up at ground level, crushed and conveyed directly onwards – without the need for elaborate foundation work.
Characteristic of the HHI is the horizontal material flow combining a single impact roll with an integrated heavy-duty chain conveyor, which serves as both the feed and discharge conveyor. The feed material is picked up directly on the conveyor and crushed beneath the impact roll. This design enables belt-compatible primary crushing – typically 0–250 mm – and, thanks to its compact design, makes the HHI ideal for surface and underground operation, tunnelling and spatially confined application areas.
Thanks to PLC-controlled monitoring of the impact roll and conveyor, the plant operates fully automatically and protects itself against overload or blockages. Various mobility options – from stationary to fully mobile on crawler tracks – make the HHI a flexibly deployable solution for changing locations and materials.

The Horizontal Impact Crusher HHI enables a high degree of size reduction at the same time as high throughput. By means of the variable gap setting through height adjustment of the impact roll and the coordinated conveyor technology, the result can be adapted to different material properties and transferred evenly to downstream processesifferent material properties and uniformly transferred to downstream processes.

Application Area of the HORIZONTAL IMPACT CRUSHER HHI
The Horizontal Impact Crusher HHI by HAZEMAG is used wherever large-lump, heavy or sticky material needs to be crushed and conveyed directly at the extraction point. Typical fields of application are surface and underground mining as well as the aggregates industry – with special applications in tunnelling and the recycling of concrete and demolition material.
The robust design allows reliable continuous operation and creates stable conditions for downstream conveying or processing systems.
Typical Materials
- Limestone and coal
- Ore and mineral raw materials (low to mildly abrasive)
- Concrete, demolition material and recycling material
- Clayey, sticky and cohesive materials – preferably with a run-of-mine bunker (risk of bridging)
Industries:
- Surface and underground mining
- Tunnelling and infrastructure construction
- Aggregates and cement
- Recycling and environmental technology
After-Sales Service
Even after commissioning your HAZEMAG Horizontal Impact Crusher HHI, HAZEMAG supports you with a worldwide service and support network. The goal is stable operation, plannable maintenance and economical use over the entire service life of the plant.

Questions and Answers about the HAZEMAG HORIZONTAL IMPACT CRUSHER HHI
A Horizontal Impact Crusher crushes material by means of a rotating impact roll that picks up and crushes the feed material in a controlled manner. The size reduction takes place in a belt-compatible manner in combination with integrated conveying technology.
In contrast to conventional impactors or roller crushers, the HHI combines crushing and conveying in one unit. The material is picked up at ground level, crushed and transported directly onwards – without additional handling processes.
The HHI is designed for large-lump, heavy and sticky materials. Typical materials are limestone, coal, ore, concrete, demolition material as well as wet or clayey materials.
The Horizontal Impact Crusher is used in surface and underground mining, in the aggregates and cement industry, the stone and earth industry as well as the heavy goods and bulk goods industry – particularly where high throughput capacities are required.
Through the direct transfer of the crushed material to the conveying technology, additional crushing or handling stages are eliminated. This reduces space requirements, simplifies the plant structure and supports an even material flow.
