What are VSI crusher trail plates?

VSI (Vertical Shaft Impact) crusher trail plates are components used in the construction of VSI crushers, which are machines used to crush rocks and other materials into smaller, more uniform particles. The trail plates are a type of wear part that is designed to protect the metal surfaces of the crusher’s rotor and body from excessive wear and damage caused by the materials being crushed.

The trail plates are typically made from high-quality steel or other wear-resistant materials and are located at strategic points along the rotor and body of the crusher. They are designed to be easily replaceable as they wear down over time, allowing for the continued operation of the crusher without compromising its performance or efficiency.

Overall, the trail plates play an important role in ensuring the longevity and effectiveness of VSI crushers, which are commonly used in the mining, construction, and aggregate industries.

Trail plates wear problem

Check trail plates for wear. Replace if badly worn or rotor build-up needs adjusting.

In some applications, trail plates are changed at the same time as the rotor tips – just to keep the stone bed profile constant. Regular change of trail plates maximizes rotor tip life and is often very cost-effective.

Selection of trail plates

The trail plates are the heart of the rotor. The size, position and angle of the trail plate controls the size of the rotor build-up and the flow of material through the rotor.

Incorrectly sized or shaped trail plates can result in premature wear on every rotor wear part.

Many trail plate profiles are available. For information regarding trail plate options, contact your plant representative.

The use of different-sized trail plates can create uneven build-up which may cause severe vibration. Ensure that trail plates are matched in size and shape. Differently positioned trail plates in each port may create uneven build-up which may cause vibration.

Trial plates removal

Access through the service door.

Remove trail plate retaining bolts. Bolts will be covered with build-up and will have to be knocked out with a hammer and punch. Care should be taken not to damage threads.
If trail plate is held in by the build-up, a sharp blow with a hammer will break away the build-up and allow the trail plate to fall free.
