How a VSI Crusher Works
Feed material drops through the feed tube onto the impeller table or enclosed rotor which, through centrifugal force, throws the material against stationary anvils made up of composite metal 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.

The Science Behind VSI Crushing
The Science in Vertical Shaft Impact (VSI) crushing is based on the fundamental principle of conservation of energy.
In order to provide the most energy efficient crusher on the market, CEMCO considers the complexity of three dimensional collision forces and investigates the projectile of the material by taking into account five major physical components:
1. Free fall of a body with variable mass and geometrical configuration;
2. Conversion of energy and momentum;
3. Internal and external ballistic properties including the projectile's initial velocity and impact force over time;
4. Conversion of the physical properties of solid bodies into a fluid model and replacing the classical Newtonian physics with Bernoulli's dynamic kinematics of fluids;
5. Friction.
The five major physical components of the VSI are employed into a three dimensional real time mathematical model representing functional logic relationships. A mathematical model is then utilized to observe the collision process and forces to reveal solutions for a better final product, higher energy efficiency and a lower wear cost. By using advanced next generation computer applications, CEMCO is able to import the mathematical model or CAD programs such as Solidworks and Matlab.
