Unlike other crushers that use metal components, our vertical axis mill uses the fed rocks to break itself, thus minimizing operating costs considerably compared to other crushers. The output result of these machines is of high quality with an improved cubic shape, thus making the product adequate and more demanded by the construction industry.
These crushers are used in the last stages of crushing, in other words in the tertiary and quaternary stages.
The shaft is placed inside a chamber that contains a special crushing chamber having a rock-lined ring. The material is fed into the top of the chamber with the primary amount of the feed entering the top of the rotor. The rotor throws the material centrifugally out towards the crushing chambers at extremely high speed. A secondary amount of material feed falls into the accelerated primary feed at the crushing chamber. Thus all the material is reduced in a highly turbulent material cloud contained within the crushing chamber. Reduction occurs by impact, attrition, and abrasion.
The components of our machines, as well as the materials used, are the reason for their low need for maintenance. The rotor, which is made of cast steel, is very robust, the hammers are made of alloyed manganese which strengthens its last and increases its long life.
