Impact crusher PZ MG

Impactors PZ MG for minerals crushing

The Pozzato PZ MG impact crushers have been designed in order to treat the aggregates of 30 – 150 mm and to produce 0 – 50 mm mix. This product is normally sent to the final screening (dry or washing).

Like the whole range of the Pozzato impact crushers, the PZ MGs are well known for the easy maintenance process and are equipped with four doors that are openable sideways. No special tool is required to have access into the crushing chamber when the castings are worn.

In order to hold the same sieve analysis of the product as long as possible, the PZ MG impact crushers are equipped with a special harmours-adjusting system. It also allows to change the kind of the product when it is needed, by increasing or decreasing the distance between the hammers and the harmours.

The hammers and the harmours are all made in Chrome – Molybdenum steel alloy, that guarantees the best wear resistance and long-lasting lifetime nowadays. Only the rotors protections are made in Manganese.

Normally the PZ MG impact crushers are equipped with three hammers in order to obtain the highest sand percentage possible (about 40%), but they can also be supplied with special rotors fitted with four hammers, in order to reduce the fines and increase the aggregates.

The latest version is often used after a primary jaw crusher to treat hard and abrasive rocks, like basalt, in order to produce the ideal polyhedral fractions to feed the asphalt plant.
