Processed material has a high percentage of fine with a cubical shape. There are impact armors instead of rock reservoirs in VSI crushers that have a close-type rotor.

There are 3 types of crushing chambers that can be installed according to the application.

1. Stone box system with closed rotor: This system will be generally used for processing the most abrasive and hard materials. In addition to that this system offers the lowest costs in maintenance expenses.
2. Anvil system with closed rotor: This system will be generally used for processing the medium abrasiveness and hardness. In addition to that, this system combines closed rotor systems with low maintenance costs and anvil systems with high and homogenous crushing.
3. Anvil system with open rotor: This system will be generally used for processing less abrasive and soft material. This system offers a high crushing percentage and has the advantage of accepting larger materials.
