1946 – 2026: The Invention of Impact Crushing
An idea born in 1946 continues to shape industrial crushing to this day.
With the invention of the Andreas Impact Mill, a new
principle was established that has influenced and con‑
tinuously evolved impact crushing technology ever sin‑
ce. This innovation not only laid the foundation for a
new technology, but also marked the beginning of
HAZEMAG’s history as a pioneer in impact crushing.
1946 – The Beginning
The Patent That Changed Everything
In 1946, Dr. Andreas was granted the patent for his Andreas Impact Mill.
For the first time, the principle of controlled impact force was
systematically applied to the crushing of mineral materials. This
invention marks the origin of modern impact crushing – and the
starting point of HAZEMAG.
Post‑War Period – Technology for Reconstruction
New Challenges Require New Solutions
In the years following the Second World War, the demand for high‑performance crushing technologies increased significantly. Large volumes of mineral materials had to be processed and reused. Impact crushing opened up new possibilities: efficient, flexible, and capable of producing improved product shape – forming the basis for HAZEMAG’s future development.
The Andreas System
A Patented Principle Becomes a Standard
The so‑called Andreas System describes the core structural
concept of the early impact mill.
Multiple precisely arranged impact zones enable controlled,
step‑by‑step material reduction. This system differs fundamentally
from classic compression crushers and became the foundation
of modern impact crusher concepts.
The Foundation of HAZEMAG
An Invention Becomes a Company
Building on the patented impact principle, HAZEMAG was established as a technology‑driven company.
From the very beginning, the ambition was clear: not only to
manufacture impact technology, but to continuously develop it
– practical in design, application‑oriented, and closely aligned
with industrial processes.
Decades of Development
Experience Shapes Engineering
Over the following decades, impact technology was consistently
refined.
Designs became more robust, wear concepts more efficient, and
adjustment mechanisms more precise. While the fundamental
idea of 1946 remained unchanged, it was continuously optimized from an engineering perspective.
Broad Industrial Application
Flexibility as a Success Factor
Impact crushing established itself across a wide range of industries.
Wherever high reduction ratios, controlled particle shape, and
flexible process control are required,
the impact principle has proven to be a key technology in modern processing plants.
Modern Impact Crushers
Further Developed – Not Reinvented
Today’s HAZEMAG impact crushers are still based on the original impact principle of the Andreas Impact Mill.
This principle has been enhanced by modern materials, optimized wear solutions, hydraulic adjustment systems, and digital
control technologies – meeting the requirements of today’s
plant concepts.
2026 – 80 Years of Impact Crusher
A Legacy with a Future
In 2026, HAZEMAG looks back on 80 years of impact technology.
From the first patent to today’s impact crushers, this development follows a clear principle:
efficient material reduction through controlled impact force.
80 Years of Impact Crusher – An Invention Becomes a Benchmark
What began with a patent in 1946 continues to define impact crushing today. One idea, one technology, one success story.
