The K Series Vertical Shaft Impact(VSI) crusher was improved on basis of the technology of Barmac,it has had a huge impact on the global quarrying and minerals processing industries. The Barmac K-Series VSI is unique due to its crushing process. Whereas most other types of crusher use metallic parts to crush rock, the Barmac VSI uses the rock fed into the machine to crush itself. This autogenous crushing process produces the best-shaped aggregate on the market today. The high velocity impact crushing achieved in a Barmac K-Series VSI improves the soundness and shape of stone, reducing product moisture and easing the screening task while producing superior products at a minimum cost.

• Produces a product of superior cubical shape;
• Ability to control product grading by cascading and tip speed;
• Low wear costs due to unique rock-on-rock  crushing;
• Accepts fine material in feed.
