Introduction to aggregates & sand
The Barmac VSI can manufacture sand and aggregate to meet the highest specifications for all concrete, asphalt road and other construction purposes. The Barmac VSI's unique rock-on-rock crushing action transforms low grade material into premium aggregate products, all the while ensuring low wear and operating costs.
The Barmac VSI crushes a wide range of materials and will process hard, highly abrasive rocks as a matter of course.
The high velocity impact crushing achieved in a Barmac VSI improves the soundness and shape of the stone, reducing product moisture and easing the screening task while producing superior products at a minimum cost.
In a tough market place, the best stone wins contracts. By improving product shape across the range, the Barmac VSI turns otherwise unsaleable material into premium aggregate sizes.
