HSI crushing
We are the UK’s specialist national contractor for earthmoving, crushing and recycling, and sea and coastal defence works.
Producing well-shaped aggregates with efficient reduction ratios
Horizontal Shaft Impact (HSI) crushing uses high-speed impact force to fracture material along natural fault lines, producing well-shaped aggregates with efficient reduction ratios. It is particularly effective in recycling concrete and asphalt.
OEC deploys HSI crushers to sustain, protect and enhance material recovery operations. We sustain resource value by converting demolition waste into reusable aggregates. We protect downstream plant through controlled feed and integrated metal separation. We enhance output quality by producing cubical, evenly graded material.
HSI crushing is suited to:
- Recycling reinforced concrete
- Asphalt processing
- Secondary reduction after jaw crushing
- Producing high-quality sub-base material
Adjustable impact aprons allow control over final product size, while integrated screening circuits ensure accurate separation and minimal oversize recirculation.
Within complex construction and regulated environments, our impact crushing operations are delivered with disciplined dust suppression, noise control and environmental compliance.
All loading shovels are equipped with on-board weigh loaders and printers, ensuring accurate material measurement and transparent reporting. Excavators operate with pulverisers, hydraulic breakers and magnets, enabling efficient material segregation and preparation prior to processing.
As part of OEC’s wider crushing and recycling capability, HSI crushers provide flexible, high-output processing that improves material usability while maintaining operational control and programme efficiency.

Frequently Asked Questions
Need to Know More?
Horizontal Shaft Impact (HSI) crushing is used to break material using high-speed impact forces, producing well-shaped, evenly graded aggregates. It is particularly effective for recycling concrete and asphalt due to its ability to fracture material along natural fault lines.
Ovenden Earthmoving Co Ltd (OEC) provides mobile HSI crushing services across the UK as part of integrated recycling and crushing operations. We process reinforced concrete, asphalt and secondary crushed material to produce high-quality sub-base and construction aggregates.
OEC uses controlled feed systems, adjustable impact aprons and integrated screening to manage product size and consistency. This ensures cubical, evenly graded output while reducing oversize recirculation and maintaining efficient, high-output material recovery.
