A vertical shaft impact crusher, or a VSI crusher, is mainly used in the construction industry to produce premium-shaped aggregates, high-quality manufactured sand for building roads, etc. Besides, in some areas like Africa, Australia, and Brazil, VSIs can also be used in the mining industry. The rotor is the most crucial part of a VSI crusher.

Design to represent the crusher and rotor geometries in the system. The modelled VSI is based on measurements from a Barmac 5100SE VSI crusher taken from a mobile crushing plant located in a quarry in Gävle at the time. Eight different rotor designs were created in a systematic way using a Design of Experiments approach.
VSI crushers include a patented, 3-port rotor, hopper design and Bi-Flow™ technique to create a more cost-efficient output. Fewer parts in the upper part of the rotor and a smart bearing design reduces out-of-balance forces and power consumption, achieving a lower cost per ton and greater uptime.
VSI crusher can be considered a 'stone pump' that operates like a centrifugal pump. The material is fed through the center of the rotor, where it is accelerated to high speed before being discharged through openings in the rotor periphery. The material is crushed as it hits of the outer body at high speed and due to rocks colliding against ...
Published Mar 7, 2023. + Follow. A VSI (or Vertical Shaft Impactor) crusher works by accelerating material into a crushing chamber where it is then impacted by a high-speed rotor. The rotor is fed ...
Rotor body X. There are different rotor body styles. Most common are 3-bar and 4-bar rotors. This example is a 4-bar rotor that can be operated in the following two operation modes: 4 high bars: this mode is for processing small materials (e.g. asphalt millings or gravel) or in a secondary crushing application (e.g. after a jaw crusher)
B Series Deep Rotor VSI Crusher is a series of vsi crusher, ... modular-design hammer, just to replace worn parts when wear out, it can reduce cost more than 30%. REMco's common VSI questions. Can VSI crushers make the same products as a cone crusher? Yes! ... If the REMco VSI rotor is in proper balance, vibration is nil or often non-existent.
Design to represent the crusher and rotor geometries in the system. The modelled VSI is based on measurements from a Barmac 5100SE VSI crusher taken from a …
A VSI operates differently from other crushing machines, such as jaw crushers or cone crushers. It uses a high-speed rotor and anvils to create impact forces that break down the materials. This unique mechanism requires a deep understanding to ensure efficient and effective operation. ... The efficient design of the VSI rotor ensures …
The rotor of deep rotor VSI crusher has been specially optimized design which makes the capacity increased by about 30%. Around guard adopts innovative design to improve the service life of over 48%. Increase vice hammer to prevent from damaging the side plate after the main hammer wear and tear.
Furthermore, the capacity ot the dedusting system can be reduced. The open design of the patented rotor with two chambers allows the maximum possible material outlet size (89° per side of the rotor). This significantly reduces the risk of clogging. In the twin-chamber rotor, a material bed forms along the centrifugal chambers, resulting in...
Nesans CF Series Vertical Shaft Impact Crusher are high impact force, tertiary stage, high output ratio crushers. Uniquely designed to achieve the required product gradation for the production of m-sand. With dynamically balanced rotor design and robust rotor tips, CF Series Vertical Shaft Impact Crusher can save a huge on your maintenance costs.
Published Jan 4, 2023. To reduce the noise from a VSI crusher, you can use acoustic enclosures, which surround the machine and absorb the sound. Additionally, you can switch to less-noisy parts ...

The purpose of this article is to present a novel mathematical-physical model for the design of a new conical-shaped centrifugal rotor for vertical shaft impact crushers (VSI's) to reduce energy consumption. Many models of flat disced centrifugal rotors have been developed, however, these models do not use mathematical-physical relations to ...
The efficient and versatile design of Kolberg-Pioneer, Inc.'s Vertical Shaft Impactors (VSI) delivers highly-consistent end products for jobs that demand precision. Our VSI crushers are available in both stationary and portable configurations and produce up to 500 tons per hour. With the ability to run in standard, semi-autogenous and fully ...
Rotor speed is the rate in RPM that the rotor is spinning in the crushing chamber. We cal-culate the Rotor speed (RPM) using the fol-lowing formula: Motor RPM x Motor Pulley diameter (mm) / Crusher Pulley diameter (mm) Tip speed is the speed in metres per second that the rotor tip is spinning on the outside of the rotor.
Barmac® crushers are particularly successful in producing road-base, top dressing chip, concrete and asphalt aggregates. In these applications, Barmac® VSI crushers can be operated either in open or closed circuit, depending on the types of aggregates and the specifications required. Manufactured sand production.
