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.

 Rock-on-rock process action

Barmac K Series VSI is usually applied in the last phase of the crushing circuit. The quarrying and construction industry has always been Barmac K Series VSI 's main application area with thousands of units operating around the world, followed by many demanding manufactured sand, heap leaching, pre-grinding, industrial minerals and recycling applications. This is possible because of the unique free-impact crushing and grinding action combined with the ability to accept fines in the feed and to fine-tune the crusher's performance by simply changing the rotor speed or cascade ratio.

Cascading optimizes quality

The primary path for the feed material is through the stone lined rotor where material can be accelerated up to rotor tip speeds of 80 m/s (262 ft/s) before being discharged into the crushing chamber. Additionally, material may be cascaded into the crushing chamber, bypassing the rotor.
