Most operations will use a gyratory, jaw or impact crusher for primary crushing. In the secondary and subsequent stages, the stone is further reduced and refined for proper size and shape, mostly based on specifications to produce concrete and asphalt. Between stages, screens with two or three decks separate the material that already is the ...

The use of vertical shaft impact (VSI) crushers is one possible solution, since VSI crushers can create particles with a good aspect ratio and smooth surfaces for use in different applications ...

RUBBLE MASTER mobile impact crushers use a proven and powerful diesel-electric drivetrain. Contrary to many traditional crusher manufacturers RUBBLE MASTER has been using this highly efficient drivetrain since our beginning in 1991 because of …

Impact stone crusher involves the use of impact rather than pressure to crush materials. The material is held within a cage, with openings of the desired size at the bottom, end or at sides to allow crushed material to escape through them. Impact stone crusher is used with soft materials, medium to hard stones and medium hard metallic ores.
