Concrete Crushers v. Impact Crushers

Lower costs. Better efficiency. Increased performance.


Two of the most popular aggregate processing machines are concrete crushers and impact crushers. Both types of crushers serve the same purpose, to break large rocks into smaller fragments, but what are the differences between these two machines? Which one is right for your operation? And, where do you find concrete crushers for sale? Keep reading to find out.

What is a Concrete Crusher?

Concrete crushers are the industry go-to for primary concrete and rock crushing. They are able to handle the hardest and most abrasive materials like quartz, granite, and riverstone. Concrete crushers are also able to process materials that have rebar or wire mixed in. Some concrete crushers have a magnetic conveyor, like the Senya 6, that automatically removes metals.

Concrete crushers work by compressing raw materials to reduce their size. A boulder is fed into a V-shaped chamber with two plates – one is stationary and the other moves back and forth to squeeze the rock. When the rock is small enough, it falls through the opening at the bottom of the chamber. Raw materials are reduced to a size between 1 and 35 centimeters depending on the desired output settings. The aggregate produced is unevenly shaped with sharp edges. Concrete crushers also produce less dust than other rock crushers.

What is an Impact Crusher?

Impact crushers are better suited for softer materials like clay, coal, and limestone. Though concrete crushers can be used in secondary crushing, an impact crusher can be used instead to produce smaller aggregates. Reduced aggregate is less than 20 centimeters in size. Impact crushers produce more uniform shaped aggregate that can be used to sell items like decorative gravel.

Impact crushers reduce materials using a flywheel with blow bars attached that throw the material against the wall of the crusher. Materials that react to moisture, like asphalt, are processed especially well with an impact crusher.

Which One Should You Pick?

Whether you pick a concrete crusher or an impact crusher will depend entirely on your production needs. Things to consider when picking a concrete crusher are how the crusher works, the types of materials you intend to crush, and the type of aggregates you want produced.
