PRODUCE UNIFORM, ROAD-MAKING MATERIAL
Usually positioned after your primary or secondary crusher, Vertical Shaft Impactors (VSI) consistently produce cube-shaped material. The shape and size of the final product is a spec required by most modern asphalt contractors including “Superpave.”
During production at the quarry, 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.
Compared to compression crushers like jaws and cones, impactors accept larger feed sizes, process higher tonnage and allow customization of particle shape and size.
Superior builds more than a dozen VSI models:
- Maximum feed size up to 8″ (203mm)
- Product size of 1″ – Minus #8 (-2mm)
- Maximum tonnage rate of 500 STPH (450 MTPH)
Features & Benefits
Belt Drive Model
Externally adjusted, it allows for safe modification of the feedtube without opening the crusher.
An integrated switch protects the crusher from failure caused by imbalance, while anti-vibration mounts isolate the crusher from surrounding equipment.
Cuts power to protect operators during maintenance while a support arm prevents the lid from lowering if hydraulic pressure is lost.
Simple hydraulic controls allow safe access to crushing chamber.

benefits of impact crushing
When utilized correctly, impact crushers are absolute rockstars! They produce some of the highest value, highest quality material in the aggregates industry
Most of the time, we rely on our dealers to stock Superior equipment. However, we typically have a small amount of factory stock.
Service & Parts
We always have been and always will be a privately-owned company. That means we can add more employees to our customer service team without Wall Street breathing down our neck. Isn’t that the way it should be?
They’re the same neighbors you’d trust to babysit your dog on the weekend. Our factory-trained dealers are a local connection for sales, service and parts.
Staffed by agents born to serve others, you’re welcome to call our technical service team 24/7/365. (If you call in the middle of the night, we can’t guarantee they’re in uniform!)
You know the old saying…”square pegs don’t fit in round holes?” It’s often the case with knock-off parts. Genuine Superior parts are forged from the same steel as our equipment
