If your aggregate or mining operation demands higher sand output, superior cubicity, and operational flexibility, RD VSI are the ideal solution. With advanced process adaptability and automation capabilities, they empower you to optimize performance and achieve consistent, high-quality results.
RD VSI – Engineered for precision. Built for performance. Designed for your success.
A Vertical Shaft Impact (VSI) is an impact crushing technology to crush rock-on-rock or rock-on-steel by utilizing the kinetic energy of fast moving material․
The feed material is introduced into the center of a spinning rotor and ejected outward against stationary anvils or a chamber lined with rock․ Rock-on-rock impact crushing is the method of choice for the manufacture of uniformly shaped‚ high quality aggregates․
The VSI has a very strong build which allows it to perform efficient size reduction․ Thanks to the strong rotor and crushing chamber‚ material size can be easily controlled‚ as can the overall throughput‚ by adjusting both the rotor speed and the feed rate into the machine․
At RD Group‚ our VSI deliver outstanding manufacture with fantastic value․ At the core of each VSI is a customer benefit driven design that ensures outstanding benefits to productivity‚ reduced costs and extraordinary quality:
RD VSI Delivering performance, efficiency, and profitability in every operation.
At the core of every RD VSI lies its intelligently engineered rotor—designed to deliver maximum performance with minimum wear. Built with a strong focus on serviceability and durability, the RD rotor ensures reduced maintenance and longer operational life.
Its optimized design allows greater material intake and smoother material flow through the rotor, significantly reducing power consumption while minimizing rotor and wear part damage. This results in improved efficiency, lower operating costs, and consistent high-quality output.
With RD’s advanced rotor technology, you get enhanced productivity, superior reliability, and maximum return on your investment.
RD Rotor – Engineered for power, efficiency, and long-lasting performance.
VSI Crushers generate high-quality cubical aggregates, provide much better product consistency, and can achieve lower operating expenses because of less wear and high efficiency in using energy.
VSI is effective in grinding hard and medium-hard granites such as basalt and granite and recyclable materials, such as concrete, asphalt, and slags.
The rotor flings the material and it hits other rock material which walls the chamber of a crusher. This promotes the fracture along grain lines giving a good quality cubical production.
Our VSI crushers are constructed of long-wearing materials and wear-resistant liners with a long life of operation- usually many years even considering maintenance and specific end uses.
Yes. The ability to regulate rotor speed gives operators the chance to optimize particles sizes and shape as per the specific applications.
