Vertical Shaft Crushers

VSI crushers are the tertiary type of crushers used to crash the hard and abrasive materials between 0-45 mm, bring them into cubic shape and obtain sand. VSI crushers are produced in two types as closed rotor and open rotor. The vertical shaft types of crushers with closed rotor are fed with stones maximum size of 0-45 mm. because some large material in return of the crashed material can leave on the screen; these types of crushers are not suitable for crashing the returned material.
VSI crushers shoot and crush the material, which entered into the rotor, by throwing them to the lining of stones "stone box" which formed in the stator naturally and to the materials which entered in the system from the outside of the rotor with a speed of 67 - 80 m / s approximately (crushing stones by hitting stones). VSI crushers are used to crush the materials having hardness lower than the grade 9 with a moisture content of less than 9%. Non-flammable and non-explosive mining materials have to be used.
