Pioneers of Impact Crushing

In the early 1960’s, after observing shortcomings in existing crusher technology, CEMCO (acquired by Superior in 2023) embarked on a journey to design a better crusher for chips and sand production.

The result was the creation of the modern vertical shaft impact (VSI) crusher, a pioneering design that has stood the test of time with the first unit still operating today!

Today, Superior’s Cemco VSI boasts global usage, persistently processing a wide range of materials in diverse industries.

T80 Cemco VSI -Simple Maintenance with hydraulic lifter lid

Hydraulic Lid Lifter

Provide quick access for routine inspections and quick and easy maintenance.


Interchangeable chambers

Accommodates several rotor and anvil configurations for application flexibility.


Replaceable Rotor Assembly

Pedestal style component is replaceable but can also be rebuilt in your shop.


Adjustable Feed Tube

Allows for external adjustment of the feed tube without opening the crusher.

How Does the Cemco VSI Work?

Feed material drops onto the impeller table or enclosed rotor which, through centrifugal force, throws the material against stationary anvils made up of composite alloys

When the rock impacts the anvils, it shatters along natural stress lines, creating a uniform, cubical product. This method of crushing is simple and economical to operate.
