Primary Crusher an overview ScienceDirect Topics

The primary crusher converts the feed size to one that is acceptable to the secondary crusher. Pivoted hammers are pendulous, mounted on the horizontal axes symmetrically located along the perimeter of a rotor and crushing takes place by the impact of material pieces with the high speed moving hammers and by contact with breaker plates. A cylindrical grating or screen is placed beneath

Selecting the right type of crushing equipment Quarry

4/7/2016 Vertical shaft impact crushers Generally recognised as a tertiary crusher, vertical shaft impact crushers (VSIs) have material fed into the centre of the crusher through a feed tube and onto the centre of a rotating table or rotor. The material is then accelerated to high velocity and is thrown into the anvil ring or outer shell. Crushing takes place upon impact with the anvil ring or

1/4/2019 Generally, in the primary stage, rotors with four blow bars are used at rotor speeds of 25 35 m/s. In secondary crushers, pre-crushed material with edge lengths of 150 280 mm gets crushed. Even harder rocks like granite or basalt can be processed. The rotor rotates at around 35 48 m/s and is equipped with four blow bars. With this, a product of < 35 mm can be produced. Secondary
