The rotor, being the heart of the Vertical Shaft Impactor (VSI), is designed for high capacity with a low power consumption. The wear parts for a VSI rotor are contained both within and on the outer surfaces of the rotor. Different parts have material technology to resist either impact or abrasive wear.
Selection of the correct wear parts for the application required is fundamental to ensure the desired performance.
NFLG holds a huge stock inventory of premium quality compatible spare parts and wear parts to suit a popular range of VSI, including:
Eliminator series rotor is the traditional and well-established style of rotor for Barmac capable of performing in all applications. NFLG holds the most spare and wear parts of this kind of rotor in-stock to support your machine. The features of this rotor are:
Now NFLG is able to supply the lastet technologies of Metso Barmac VSI rotors, the RC series rotor. It keeps your VSI crusher up and running longer than ever before. The features of this rotor are:
Barmac B-Series VSI crushers have many different wear parts inside the Rotor. Including:
The wear parts that are worn the most inside the rotor are the Distributor plate, Rotor Tips, Lower wear plates and Feed tube. This happens because these parts have direct contact with the feed material at all times as it passes through the rotor.
The distributor plate is the wear part that receives the most impact wear(material feeding), and will normally wear out the fastest in standard applications. There is only 1 distributor plate in each dressed rotor.
The Rotor tips are the last thing to touch the feed material as it exits the rotor. They can have a Tungsten insert that improves wear life. We often use the life of the tips as a reference point for the other rotor wear parts.
These wear plates are designed to protect the upper and lower faces of the inside of the rotor from the feed material as it passes through the rotor (the material build-up protects the sides).
The back-up tip is designed to protect the rotor if and when a rotor tip gets broken or worn out. When this happens the Tungsten insert in the rotor tip has split and is now letting feed material run against the Tungsten insert of the back-up tip.
Tip / Cavity Wear plates are designed to protect the outside edges of the rotor against excited particles in the crushing chamber. As the rotor spins, it impacts against particles that have rebounded from the chamber build-up after their initial exit from the rotor.
The Trail plates are designed to hold in the material build-up inside the rotor behind the rotor tips. They can be the least expensive wear part in a rotor, but as they are responsible for keeping the build-up in place, they are very important.
The Feed tube is subject to high abrasive wear as all of the feed material going through the rotor will pass through it. The Feed tube is secured into the Spider assembly of the crusher using a clamp plate and spring handle.
The Feed eye ring is subject to minimal wear in normal operating conditions, and in some rotors can be turned 3 times to maximise wear life. The Feed eye ring is secured to the feed opening of the rotor either with bolts or by dropping into slots and rotating to lock.
The Top and Bottom wear plate are designed to protect the top and bottom outside surfaces of the rotor. The top surface can get worn when the feed tube and feed eye ring are worn letting material though the gap created in the rotor feed opening. The bottom surface can get worn when material build-up in the crusher base becomes excessive and starts pushing upwards against the rotor.
NFLG® offers different designs and manufactures various solutions of blow bar for an extensive range of OEM vertical shaft impact crusher brands including: Metso Barmac, Sandvik CV, Trio TV, Canica and others.
