HPI Series
IMPACT CRUSHER
The impact crusher is a key technology for crushing medium-hard to hard rock. With its high reduction ratio, it efficiently processes large feed material and prepares it for downstream processes. Typical applications include the cement industry, aggregates production and the recycling of construction materials and demolition waste.
HAZEMAG impact crushers such as the HPI series are designed to reliably process even very large rock pieces while ensuring a uniform particle size distribution. This precise material preparation forms the basis for efficient downstream processing, for example in vertical mills or further crushing and screening stages.
Thanks to optional features such as hydraulic adjustment systems or the innovative HAZtronic electronic control system, operation and maintenance can be carried out flexibly and safely. The result is high throughput capacity, maximum plant availability and energy-efficient crushing, delivering both economic and environmental benefits.
Your Advantages of the PRIMARY IMPACT CRUSHER at a Glance
- High Reduction Ratio: The primary impact crusher ensures efficient pre-crushing of large feed material – up to 3 m³ – while maintaining a consistent product size and high throughput.
- Optional Grinding Path: Depending on the application, the crusher can be operated with or without a grinding path, allowing precise control of particle size distribution and effective limitation of oversize material.
- Energy-Efficient and Economical: The optimized HAZEMAG drive system significantly reduces energy consumption and lowers operating costs, even in demanding continuous operation.
- Easy maintenance: Thanks to wedge fixing systems and hydraulic adjustment, blow bars, grinding paths and impact aprons can be replaced quickly without fully emptying the crushing chamber. This minimizes downtime and simplifies regular inspections.
- Maximum flexibility – Ideal for demanding applications in recycling & quarries
