The first crusher was a "basic" VSI in concept. We learned a great deal about manufacturing and applications since our first crusher was built in 1967, but that first machine is still running in a mine in New Mexico. CEMCO continued to build the TurboTM Vertical shaft impact crusher and entered into an agreement with WCA to also build the

Abstract The shape of concrete aggregate fines, with particle sizes between 3 µm and 250 µm, produced by high-speed vertical shaft impact (VSI) crushing of 10 different rock types from quarries in Norway, has been studied by both dynamic image analysis (DIA), which is a 2-D method, and X-ray microcomputed tomography (µCT) coupled with spherical harmonic (SH) analysis, which is a 3-D method.

Impact crushers are traditionally classified to two main types: horizontal shaft impact (HSI) crushers and vertical shaft impact (VSI) crushers. These different types of impact crushers share the crushing principle, impact, to reduce the material to smaller sizes, but features, capacities and optimal applications are far from each other.

The most important factor when designing a crushing circuit is how to apply the two primary methods of crushing aggregate – compression and impact. horizontal-shaft impact (HSI) crushers and vertical-shaft impact (VSI) crushers. Jaw crushers are generally considered a primary or first-stage crusher. The maximum feed size can be as

The product from VSI crushers have been used to show that this resulting product can be used instead of natural gravel. In other words, it has been used to remove the dependency on natural gravel in some regions, but some plants have not achieved this. Figure 3.

The Vertical Shaft Impactors or VSI Crusher are one type of impact crushers, which offer higher reduction ratios at a lower energy consumption. These impactors. can be considered as a ‘stone pump’ operating like a centrifugal pump. The 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.

What is an Impact Crusher? Compared to the compression style of crushing, impact crushing crushes rocks at high-speed with a rotor that hits and throws the rocks into the curtain or apron which further reduces particle size.. Given that the inserted rotors (VSI and HSI) operate at high speeds, impact crushers are best suited to materials with a low work index (low hardness), low silica levels
