Different designs for soft and non abrasive feed material or for medium hard and slightly abrasive material are available. For hard and abrasive material, crushers have special heavy-duty design of the body, rotor and the breaker bars and blowbars are with higher chromium content castings. These crushers are also equipped with a third breaker plate producing higher amount of fines.

MEKA MSI Series Secondary Impact Crusher is ideally suited to crush soft to medium hard materials of medium to low silica content such as limestone, gypsum.  MEKA MSIH Series Secondary Impact Crusher is the economical alternative to cone crushers for hard stone. They are suitable for several raw mineral materials with varying degrees of hardness, from soft to brittle materials to hard rocks and iron free recycling material.

The materials are crushed by the impact force generated by the blowbars fixed on the rotating rotor.With the impact of the material on the blowbars on the rotor, the material hits the opposite breaker plates and a secondary crushing takes place.

Secondary impact crushers are designed for the secondary stage for high throughput and cubical end products. High reduction ratio and high production make impact crushers ideal crusher for large capacity projects .Energy cost per ton of product produced is low.

Secondary Impact crusher is used in the secondary stages of the crushing process for different kinds of materials. They produce cubical and high percentage of end products, and the fines production rates in the end product are also very high.
