They are recommended in many industries such as aggregate, metal recycling, cement and sugar industries for crushing brittle materials of low hardness. The hammer crusher consists of a row of swing hammers that are hinged in a central shaft. The high-speed rotation of the rotor helps the raw material to be crushed by the hammers into the crushing case.
