PRIMARY CRUSHING

Rotor-type crushers are heavy-duty machinery, suitable for primary crushing of common limestone, of low or medium hardness. Their operation is based on the crushing of the rock through multiple impacts between their moving parts (rotor) and the fixed parts of the body and jaws. The output is mostly cubiform, free from fractures and natural weaknesses. These crushers are built in different sizes, according to the desired productivity, as shown in the following table and technical features.
