High Reduction Ratio and Energy-Efficient Processing for Maximum Plant Performance
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.
- Robust construction: The patented GSK rotor cast-welded structure and wear-optimized blow bars ensure long service life and reliable performance – even when processing abrasive materials.
- 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.

Particle Size Curve without Grinding Path | HPI Series
The particle size curve shows the typical screening curve of the HPI primary impact crusher when operating without a grinding path. It illustrates the resulting particle size distribution depending on feed material, crusher settings and material properties, and supports the design of downstream screening and conveying stages.
Particle Size Curve with Grinding Path | HPI Series
This particle size curve illustrates the screening curve of the HPI primary impact crusher with grinding path. Due to the additional oversize control, the particle size distribution shifts toward more defined final product sizes. The diagram supports the planning of screening circuits, recirculation rates and the desired product quality.
Application Areas of the HPI Primary Impact Crusher
The HAZEMAG HPI primary impact crusher is used wherever large feed material must be reliably and energy-efficiently pre-crushed. Typical applications include the cement and aggregates industry, quarrying operations, and the recycling of concrete and demolition waste. With the optional grinding path, the crushing process can be flexibly adapted to different material properties – from soft limestone to harder dolomite.
The robust design of the impact crusher allows continuous operation even under harsh conditions. Thanks to its high reduction ratio, the machine produces a uniform particle size distribution, creating ideal conditions for downstream grinding mills or screening processes.
Typical Materials
- Mineral raw materials such as limestone, dolomite, granite, basalt, sandstone and shale
- Raw materials for cement and construction materials production such as lime, gypsum, clay and chalk
- Recycling materials such as concrete, reinforced concrete, demolition waste, bricks and masonry
- Aggregates such as gravel and crushed sand for asphalt and concrete mixtures
Example from Mineral and Industrial Processing
In a typical mineral processing plant, a HAZEMAG impact crusher can be used in a downstream crushing stage to further reduce pre-crushed material in a controlled manner. Depending on the application, materials such as limestone or comparable aggregates may be processed where a defined particle shape and consistent final size are required. Through impact-based crushing, the material can be efficiently fractured and optimally prepared for the subsequent screening stage.
Impact crushers can also be used in industrial processing operations to further process mineral bulk materials and achieve a stable screening curve for downstream process steps. This results in a homogeneous end product that can be reliably used in further industrial applications while supporting stable and efficient plant operation.

Questions and Answers about the Primary Impact Crusher HPI
An impact crusher works using impact energy. The material is accelerated by rotating blow bars and thrown against impact plates, where it breaks into smaller pieces. This process produces a uniform particle size distribution with high throughput.
A crusher is a machine used for the industrial size reduction of rock, ores and recycling materials. Common types include impact crushers, jaw crushers, cone crushers and roll crushers. The choice depends on material type, feed size, desired product size, throughput, energy consumption and wear requirements.
An impact crusher reduces material using impact energy. The feed material is accelerated and thrown against impact plates, resulting in high reduction ratios and a well-shaped final product. Impact crushers are commonly used in the cement industry, aggregates production, and in the recycling of concrete and demolition waste.
A roll crusher, in contrast, works with compressive and shear forces between two counter-rotating rolls. This process produces a very uniform particle size distribution with low fines and is particularly energy-efficient. Typical applications include the processing of limestone, clay, gypsum, coal and phosphate materials.
A primary impact crusher mainly processes medium-hard to hard rock as well as mineral materials with large feed sizes. Typical materials include limestone, dolomite, marl, sandstone, as well as concrete and demolition waste from recycling applications.
Due to its crushing characteristics, the primary impact crusher is particularly suitable for applications in the cement industry, aggregates production, quarrying and recycling, where high throughput rates and a consistent particle shape are required.
The HAZtronic control system is an intelligent electronic system for the automatic adjustment and monitoring of crushers. It ensures that impact aprons or rolls are positioned precisely, safely and reproducibly, enabling optimized crushing performance and stable operating conditions.
