Pioneers of Impact Crushing. In the early 1960's, after observing shortcomings in existing crusher technology, CEMCO (acquired by Superior in 2023) embarked on a journey to design a better crusher for chips and sand production. The result was the creation of the modern vertical shaft impact (VSI) crusher, a pioneering design that has stood ...

1. Introduction. Impact crushers have become particularly useful in manufactured aggregates production because of the nature of the breakage mechanisms, which allow direct fragmentation of the particles without leaving residual stress in them (Wills and Finch, 2016).As such, material produced in a particular size range, which may …
Use a spirit level to be sure the rotor balance machine is level. Make sure there is no loose material or wear parts in the rotor that could move as it is turned. Balance the rotor with top and bottom wear plates.
This force rotates with the shaft. Normally N is used to denote shaft speed in RPM. Example 2.2 Rotor Unbalance Eccentricity and Force Given: A rotor mass has an unbalance of U= 10 oz-in (7.064 N-mm) and a weight of W= 500 lbf (2, 225 N) The rotor speed is N= 8, 000 RPM. Objective: Find the unbalance eccentricity eu, shaft angular …
The results have revealed that a daily energy cost saving of 41.93% can be realized. The authors in Numbi and Xia (2016) have conducted a study aiming to minimize the energy cost of a crushing circuit based on a vertical shaft impactor. The results have shown that up to a 49.7% energy cost saving can be achieved. Show abstract.
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 …
The VSI crushers are delivered with a fixed rotor speed depending of the crusher model. It is possible to order different pulleys and taper locks that will change the rotor speed. However, the fixed rotor speed is chosen with many years' experience in mind and the benefits of changing to other rotor speed can only be seen in few cases.
Produce Uniform, Road-Building Material. Compared to compression crushers (jaws and cones), impact crushers – like the Valor Vertical Shaft Impactor (VSI) – process a wider range of material at higher tonnages and allow for more customization of rock shape and size. Our Valor VSI offers significant application flexibility because of options like …
Horizontal shaft impactors (HSI) offer the adaptability and capacity required to meet producer expectations. With three- or four-bar configurations, large feed opening and high-performance MPR rotor, Astec impact crushers are well-suited for a variety of applications. With 30% more uptime and 25% more production than competitive models, our ...
1. Introduction. Vertical shaft impact (VSI) crushers are processing machines which are usually used in tertiary crushing stations of both aggregate and mining industries for crushing of hard rock material or ores when a product material with cubical shape and large amount of fines is required [1], [2].When compared to other tertiary …
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 …

Type A: Rotors without journals, balanced on a vertical machine (or balanced on a horizontal machine …
The vertical shaft impact (VSI) crusher is a commonly-used machine in aggregate production. A comprehensive understanding of the physical phenomena that influence the power consumption and the ...
Vertical Shaft Impactor Benefits Enclosed metal rotor shoe on metal anvil The enclosed top plate on a rotor primarily prevents material from escaping from the top of the rotor, which could happen with an overfed open top rotor. Vertical Shaft Impactor Applications VSI Crushers (Above: Rock shelf when VSI at rest.
To improve the balance condition of most high speed flexible rotors, the following procedure is generally followed: 1. Balance the bare shaft without added components. a. Assure that any keyways are fitted with half keys in accordance with ISO 8821 unless two keys are located at the same axial position and are 180⁰ apart. 2.
The efficient and versatile design of the Astec vertical shaft impactors (VSI) delivers highly consistent end products for jobs that demand precision. Astec 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 autogenous ...
The model developed in Section 2 has been implemented in an in-house FORTRAN code. It has been validated with pilot-plant experiments performed on a horizontal-shaft impact crusher with rotor diameter and width of 0.65 and 0.45 m, respectively. The rotor radius is R=0.325 m; the height of the rotor impact bars is H b …
In a VSI, material is accelerated by centrifugal force by a rotor against the outer anvil ring, it then fractures and breaks along natural faults throughout the rock or minerals. The …
A rigid rotor can be balanced at the two end planes and will stay in balance when in service. A flexible rotor will require multi-plane balancing. If a rotor is balanced on a low speed balancing machine assuming it is rigid and then in service becomes flexible, then unbalance and thus high vibration, will be the result.
