Alquezar has a range of vertical sand mills with productions that vary from 150 Tn/h to 500 Tn/h, thus covering the majority of the demand of aggregate crushing processes. These are ideal for the secondary and tertiary crushing stages and as shape correctors, as the impact crushing provides for perfect cubic-shapes.
The vertical crushers are available in two versions: standard, where the crushing takes place due to the impact of the material against the actual material, obtaining rounded edge aggregate with a small percentage of fine grain, and the version with impact plates, where the aggregate knocks against cast iron hammers producing sharp-edged crushed material and a higher content of fine grain.
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 VA 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.
