TG-VSI 200 Vertical Shaft Impact Crusher

Centrifugal Impact Crushing with Self-Renewing Chamber Lining

The TG-VSI 200 uses centrifugal force to accelerate material against a rock-lined crushing chamber, fragmenting brittle metal through high-velocity impact rather than compression or shear. Feed material enters the rotor from above, is accelerated outward through centrifugal impeller channels, and thrown against the chamber wall at high speed. The impact shatters brittle metal along grain boundaries and existing micro-cracks. Material that does not fragment on the first impact falls back into the rotor path for repeated cycles until it reaches discharge size.

The defining feature is the autogenous rock-on-rock chamber. Instead of metal wear plates as impact surfaces, the chamber is lined with the feed material itself-accumulated fragments form a self-renewing wear layer. Incoming material impacts this layer rather than bare metal, which eliminates chamber liner replacement entirely.

VSI vs. HSI: Which Impact Crusher for Your Application

Both VSI and horizontal shaft impact (HSI) crushers use impact force, but the delivery mechanism and resulting particle characteristics differ:

• Rotor orientation: VSI uses a vertical rotor accelerating material centrifugally. HSI uses a horizontal rotor striking material as it passes through.
• Impact surface: VSI uses an autogenous rock-lined chamber. HSI uses steel impact curtains that are a primary wear item.
• Particle shape: VSI produces more cubical, equidimensional fragments from multi-directional impact. HSI produces more angular, elongated fragments.
• Wear cost: For abrasive feed, VSI wear cost per tonne can be significantly lower since the autogenous lining eliminates chamber liner replacement.

What It Processes Well

• Metal chip and swarf reduction: Brittle machining chips reduced to uniform size for briquetting or remelting.
• Cast iron and aluminum casting fragmentation: Brittle cast components shatter under impact, producing clean fragments for foundry charging. Cubical shape improves furnace charging density.
• Slag and dross processing: Metal-bearing slag impact-crushed to liberate trapped metal particles for downstream recovery.
• Final shaping of pre-crushed metal: Material from a jaw or cone crusher passed through the VSI for particle shape improvement before screening.

The VSI is optimized for brittle, pre-sized material. It is not a primary crusher for large solid castings or thick structural sections. Ductile metals (copper, aluminum sheet) may deform rather than fragment. Confirm feed material characteristics at inquiry.

Rotor and Impeller Wear Management

The rotor impeller channels are the primary wear components. Wear parts include:

• Impeller tip plates: Bolted hardened alloy steel. First wear item to inspect and replace. Reversible where design permits.
• Distribution plate: Sits atop the rotor, distributes feed into impeller channels. Replace when wear groove depth exceeds specification.
• Rotor guard plates: Line the inner rotor housing. Inspect at scheduled intervals.

The autogenous chamber walls require no replacement-the lining continuously renews from feed material. This is the primary wear-cost advantage over HSI for abrasive applications.

Drive and Control

The vertical rotor is driven from above via V-belt drive. Rotor speed determines centrifugal acceleration and impact energy-higher speed produces finer output, lower speed produces coarser output. If a VFD is installed, the operator can adjust rotor speed to tune output size without changing mechanical components. The control panel includes motor amperage monitoring, vibration sensor, and automatic shutdown on sustained overload or excessive vibration.

Wear Parts and Support

Spare impeller tip plates, distribution plates, and guard plates are available as individual replacements. Our engineering team can configure rotor speed and impeller channel dimensions to match specific feed material characteristics. Each machine ships with a spare-parts kit; standard lead time for replacement wear parts is under 45 days. Installation supervision, operator training, and a 12-month warranty are included.
