Impact crushers are used as primary and secondary crushers. As primary crushers, impact crushers are used in limestone mainly where a high content of fines, good cubicity and angularity and a high output are required.
In modern recycling of concrete, asphalt and rubble, thanks to their high output and excellent final product quality they are indispensable. In contrast to pressure crushing, they are able to extract all reinforcing steel from the concrete and thus achieve a largely iron-free final product.
As secondary crushers, they are often used behind jaw crushers to create final products that meet the standards.
