The reversible impact crushers are studied and manufactured to produce sand and polyhedral aggregates with minimum filler content.
They can be equipped with rotor with 2 or 3 hammers on the basis of the working conditions.
According to the needs all the machines can be supplied with hammers and armour plating in Manganese steel or in special highly wear resistant alloys.

Frames are in steel plate bolted parts, for an easy disassembling.

The material, introduced in the machine from the top, is hit by the hammers and thrown on the armour-plates, to rebound again on the hammers; this operation is repeated up to the discharge opening. The reversibility of the machine enables to exploit to the utmost the hammers and the armour-plating.
