The Alquezar mills are designed with maximum operating economy in mind, optimising the durability of the wear parts and minimising the maintenance operations and consumable replacement times. The operation costs of the Alquezar ZS mills are 60 to 86% less than the operation costs of traditional bar mills. The costs are reduced because of the rotor wear linings and the change of the cast iron hammers in the version with the impact plates.

The ZS series is comprised of high-performance machines with which the granulometric curve of the material can be adjusted by varying the rotation speed of the rotor and with which an aggregate with an excellent shape coefficient and with few internal fissures is obtained, perfectly satisfying the strictest quality requirements. The rotor can be adapted to the size of the aggregate processed, using closed rotors for aggregate of up to 30 mm and open rotors for larger aggregates.
