Valor® Vertical Shaft Impactor (VSI)
Produce Uniform, Road-Building Material
Compared to compression crushers (jaws and cones), impact crushers – like the Valor Vertical Shaft Impactor (VSI) – process a wider range of material at higher tonnages and allow for more customization of rock shape and size.
Our Valor VSI offers significant application flexibility because of options like adjustable chamber configurations and several unique rotor options. Investments are backed by an industry-leading 2-year or 6,000-hour warranty.
Applications:
Manufactured Sand
Material Benefication
Precious Metals Recovery
Re-Crushing Inventory
Fractured Gravel
Cubicle Products
Man-Made Materials
Cement Clinker
Concrete Rock
Chips
Shaping
Asphalt
Advantages
01.
Hydraulic lid
Along with additional defenses, a hydraulically-controlled lifter allows safe access to chamber.
02.
Feed Tube Adjustment
Allows operators to externally adjust the feed tube for production control without opening the crusher.
03.
Air Transfer System
Available on all models, the design reduces harmful dust emissions during operation.
04.
Vantage® Automation
Designed and supported in-house, automation allows precise control, warns of harmful conditions, and improves efficiencies.
How Does A VSI Work?
During operation, feed material contacts the VSI’s rotor which rapidly launches it against stationary anvils. This collision causes the rock to break along its natural fault lines.
VSI’s are typically positioned after primary or secondary crushers and consistently produce cube-shaped material, including Superpave, which is often required by most modern contractors.
