There are two main types of impact crushers: horizontal shaft impactors (HSI) and vertical shaft impactors (VSI). HSI crushers utilize a horizontal rotor that throws the material on stationary anvils or curtains, which results in the material breaking upon impact. VSI crushers, unlike the traditional crushers, have a vertical rotor which ...

The vertical shaft compound crusher is a new type of crushing equipment developed and designed based on the technology of similar crushers at home and abroad. It can perform fine crushing and coarse grinding of many types of materials. It has a large crushing ratio, low energy consumption, energy saving and environmental protection, stable operation, …
In this thesis, the use of vertical shaft impact crushers to crush aggregate rock to rounder particles is investigated. The main aim of this is to develop and further the understanding of the relationship between the machine and material properties with respect to the resulting crushed product with the purpose to achieve an improved product.
Vertical shaft impact crushers take the full advantage of so-called rock-on-rock crushing process. In vertical shaft impact crushers, the crushable material is fed through the centre of the rotor, where it is accelerated to high speed before being discharged through openings in the rotor periphery.
A full size vertical shaft impact crusher duplicates each of the models in the ® Canica family of crushers.
The cone crusher is one of the most popular and commonly used crushing equipment in quarries, mines, and other industries. It is designed to crush materials with high hardness and medium hardness, such as basalt, granite, limestone, gravel, quartz, iron ore, copper ore, and so on. In this article, we will provide a detailed understanding of the …
A jaw crusher mainly works on the principle of reciprocating motion exhibited by the moveable jaw of the jaw crusher. The repeated movement of the jaws results in the development of compression force that further causes the breakdown of the rock or the ore placed between the two jaws into smaller pieces. The movement of the jaw crusher is ...
Two types of impact crushers exist. These are the horizontal shaft impactor (HSI) and the vertical shaft impactor (VSI). HSI crushers are the more common of the two types and can be used in primary or secondary crushing applications and construction and demolition waste recycling. VSI crushers are typically used in secondary or tertiary crushing …
Vertical shaft impactors (VSI) have a vertical shaft and enclosed rotor that turn at high speeds. There are two main types of VSI crushers, rock-on-rock (autogenous) and shoe and anvil. Rock-on-rock crushers have pockets filled with rock lining the entire circumference of the chamber.
Vertical Shaft Impact crushers have been used for a long time to reduce the size of particles and to give particles a cubical shape profile. Very few investigations have been performed on the inner workings of the VSI crusher and even fewer attempts have been made to model the particle breakage and collisions that occur inside it.
Vertical Shaft Impactor Applications VSI Crushers (Above: Rock shelf when VSI at rest. In operation, the brown rock fills the chamber to the upper roof ring. Rock impacts rock in operation.) Enclosed autogenous rock rotor table on autogenous rock shelf Any time the material or rock is used as an impact wear surface the term autogenous is used.
