Primary Impact Crusher
A primary impact crusher is an HSI-type machine used at the first crushing stage where the material is suitable for impact crushing. Rotor-mounted blow bars strike the feed at high speed and direct it toward impact surfaces inside the crushing chamber.
Typical Applications
Primary impact crushers are widely considered for limestone and similar materials in quarry, aggregate and recycling processes where a high reduction ratio and shaped product are required.
Main Wear and Service Components

Capacity and Model Selection
The Turkish legacy article gives a broad 200–900 t/h range and other generic figures. These are not used as universal specifications. Feed size, material properties, rotor dimensions, crusher setting and model determine actual performance.
