What is vertical shaft impactor crusher (VSI crusher)?

The origin of vertical shaft impact crusher

Vertical shaft impact crusher is a kind of mining machinery equipment for crushing rock and making sand, which has been widely used in China since 1980s. It is widely used in the fine crushing operation of hydropower, construction, cement, metal mining and other industries.

Main types of Vertical Shaft Impact Crushers

There are two main types of vertical shaft impact crushers, one is the material is thrown to the jaws of the crusher shell, called rock impact metal crusher, the second is the crusher has a crushing chamber that forms the shell, the rock can be natural rest angle stacked in the shell, the material with great speed impact on the rock layer.

So that some degree of crushing occurs, the rock is thrown to an inclined surface, then deflected upward to the upper part of the crushing chamber, thus turning into a crusher. The upper part of the crushing chamber, thus turning to move downward, and then continuously the rock thrown from the rotor and subjected to the second crushing action, known as impact rock crusher.

How does a VSI crusher (Vertical Shaft Impact Crusher ) operate?

A Vertical Shaft Impact (VSI) operates using a spinning rotor mounted to a vertical axis shaft. The rotational speed of the rotor (into which rock is fed vertically) in conjunction with the machine configuration (Rock on Rock, Rock on Steel, or Steel on Steel – also known as Hammer & Anvil) determines the finished product particle size.

VSI crushers are often used in tertiary, or quaternary stages of the crushing circuit, although some may be used in secondary applications depending on the size and friability of the feed material and machine configuration. These styles of crushers are used in applications ranging from sand & aggregate production to mineral processing.

In quarrying, for example, they are commonly used to produce cubical shaped aggregates ideal for concrete and asphalt applications, manufactured sand production as well as beefing up the fines content in the road base.

What are the most important VSI crusher parts?

VSI Crusher Parts
Vertical shaft impact crusher (VSI crusher) spare parts and wear parts are many, such as Anvils, Impeller shoes, Rim liners, Lid liners, Table liners, Feed tubes, Feed disks, Pedestal liners etc.

How VSI crusher parts work?

The Rotor tips are the last thing to touch the feed material as it exits the rotor. They 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.

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.

The back-up tip has a small Tungsten insert in it that will last for about 8 -10 hours of wear in normal operation. If this backup is broken again, or it wears out then the feed material can seriously damage the rotor due to abrasion.

VSI CRUSHER PARTS: CAVITY WEAR PLATE

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. As the TCWP are the furthest wear part from the centre, and on the leading faces of the rotor, then they are most susceptible to this type of wear.

These VSI crusher parts are positioned in two places on the rotor, firstly they are put on top of the rotor tips to protect the vulnerable areas of the parts, and secondly on the other side of the rotor port to protect this leading edge from wearing away and compromising the rotors efficiency.

VSI CRUSHER PARTS: UPPER AND LOWER WEAR PLATES

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).

Wear plates are kept in place using the centrifugal force of the rotor as it is spinning, there are no nuts and bolts, only some clips for the plates to slide under. This makes them easy to change and remove.

The lower wear plates generally wear more than the upper wear plates due to under utilization of the rotors maximum throughput and the use of an incorrectly shaped trail plate.

VSI CRUSHER PARTS: DISTRIBUTOR PLATE/DISC

VSI crushers have many different wear parts inside the Rotor.

Including:

Rotor Tips, Back-up Tips, Tip / Cavity Wear Plates to protect all areas of the exit ports

Upper and Lower internal wear plates to protect the inner body of the rotor

Internal distributor plate to receive initial entry impact and distribute the material to each port

Feed Tube and Feed Eye Ring to guide the material centrally into the rotor

Internal Trail plates to maintain rotor stone beds formed during operation
