Barmac VSI - How It Works (Russian)

The Barmac B-Series Vertical Shaft Impact (VSI) crusher is the original rock-on-rock VSI crusher - not a pretender.
The Barmac VSI is an ideal third or fourth stage crusher designed to crush the complete range of ores, rocks and minerals. The Barmac rock-on-rock crushing principle has revolutionised material reduction by providing a crusher that produces excellent reduction at a low operating cost.
Barmac VSIs combine high velocity impact crushing with attrition crushing to produce cubical product & quality sand. Barmac VSIs are unique amongst all vertical shaft impactors due to the pure rock-on-rock principle. Impeller shoes or impact anvils are not needed to achieve reduction.
