Vertical Shaft Crusher (VSI) produces high quality aggregates while providing low consumable costs thanks to its working principle. It is highly preferred in aggregate production, especially when cubic material is desired. They take part in the tertiary stage in the crushing and screening processes. It produces highly thin material.
There are two different designs of the crushing chamber. Stone cushioning arrangement with closed rotor is the most used type. This design is used for breaking harder and highly abrasive materials. The maintenance cost is very low.
The other type is the open rotor and armor ring cushioning arrangement. This type of design is used for breaking soft and low-abrasive materials. The size reduction rate is high. The production rate is high. Larger materials can be fed compared to the closed rotor design.
ROCK-ON-ROCK
Vertical shaft impact crusher or VSI is used as an alternative to tertiary impact crushers. It can be applied in sand quarries, quarries, ready mixed concrete and mining areas. Suitable type for this machine are stones such as hard basalt and medium granite, such as tertiary impact crushers. The main purpose is to obtain aggregates of 0-5 mm (sand) size and cubic shapes.
Advantages
Obtaining aggregate sizes suitable for concrete and asphalt production;
High sand and cubic material capacity.
Low operating cost
