New Boratas Stationary Impact Crusher VSI Series - Closed Rotor stone crusher

Unlike other crushers using metal components, Boratas Stationary Vertical Shaft Impact crusher uses the fed rocks to break each other, thus minimizing operating costs considerably. The output result of these machines is of high quality with 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.

Process of the vertical axis impact crusher

The shaft is placed inside a chamber containing 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 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 the low need for maintenance. The robust rotor is made of cast steel, the hammers are made of alloyed manganese which strengthens and increases life span.

Advantage:

• Producing a product with a superior cubic form
• Ability to control product ranking by cascade and top speed
• Low wear costs due to the unique grinding of stone to stone
• Ability to process fine materials
