HAZEMAG: Primary Impact Crusher HPI-H

Tough on Material, Gentle on Process Flow

This video demonstrates HAZEMAG’s HPI-H primary impact crusher, built for medium-hard rock. It delivers a well-graded output from zero to six inches, which makes it a common choice for aggregate, cement, and recycling operations — including pre-crushing of rubble in demanding environments.

The machine accepts feed sizes up to 1.2 m³ and covers capacities from 160 t/h to 600 t/h, depending on model.

Built for Tough Conditions

The housing is rugged welded steel plate with external bracing for heavy-duty workloads. Large doors and a hydraulic rear section give full access to the internal liners, which simplifies inspection and maintenance. The doors open hydraulically with a secure over-center mechanism that prevents accidental closure.

The 1¼-inch-thick wear liners share a common shape, giving about 95% interchangeability. That maximizes liner use, extends service life, and saves cost.

Apron and Rotor Design

The monoblock front apron is a forged manganese unit with an optional lower wear liner. Its added weight and wear zones reduce stress on the housing, improve product size control, cut downtime, and lower costs. The rear apron uses a multiblock manganese design, also fitted with a wear-resistant liner for longer life and better control of the product output.

At the core sits the heavy-duty Q rotor. Blow bars attach with a solid backing bar and wedge, so they can be rotated and reused — utilization can exceed 50%, which improves wear life and efficiency.

Grinding Path for Cement Applications

An optional grinding (third crushing) path refines the output for vertical roller mills and improves control over product grading. Adjustable steps and hydraulic retraction protect against overload and tramp iron, which supports safety, productivity, and uptime.

HAZtronic Control and Monitoring

The HAZtronic system provides computer-controlled hydraulic adjustment of the aprons and grinding path. Operators fine-tune gaps, manage product size, and work from pre-set configurations for different materials — which also reduces downtime and operating cost.

A touch-screen control panel handles aperture adjustments and real-time diagnostics: apron positions, bearing and hydraulic temperatures, and fluid levels.

What You’ll See in the Video

The footage shows the HPI-H at work: crushing cycles, the apron and liner systems, the rotor and blow bar arrangement, the grinding path, and the hydraulic adjustment and access features described above.

If you need a primary impact crusher that balances ruggedness, product control, flexibility, and safe maintenance for rock or recycling duty, the HPI-H is built for exactly that.
