Consistent quality sand manufacturing with Barmac VSI crusher
The more cubical, rounded and consistent the sand is, the better is the performance in concrete and asphalt. Whereas most other VSI crushers use metallic parts to crush rock, Barmac VSI uses the rock fed into the machine to crush itself. This autogenous crushing and grinding action provides the lowest cost per ton of any impact crushing method. The high velocity impact crushing achieved with Barmac VSI improves the soundness and shape of the material.
Barmac VSI offers unique benefits for sand manufacturing. The gradation curve can be controlled by a wide rotor tip speed range and cascading material into the crushing chamber by passing the rotor. Another great benefit is consistent end product quality throughout the lifetime of wear parts.
Improved concrete quality
Key performance indicators in the concerete industry are workability, strength and production costs. High-quality sand is the most significant component affecting these.
Higher compressive strength with manufactured sand
Savings in cement due to consistent sand quality
