Australian Made Vibrating Screens and Vibrating Feeders

Vibration isolators are required on vibrating screens and vibrating feeders to prevent vibration from passing into supporting structures.
The three types of isolators are:

Steel Coil Springs

Steel coil springs are the most common type of isolating support on vibrating equipment. This is due to their low cost, high isolation and reliability.

On vibrating screens and vibrating feeders the springs can either be attached via a spigot or bolted via pig tail ends.

Oscillating Mounts

Oscillating mounts are a steel and rubber assembly designed to provide a greater vibration isolation. Their cost is higher but they work better when starting and stopping direct drive equipment compared to steel coil springs.

They allow vibrating screens to be suspended from above easily and the bolted connections add a level of comfort that the unit will not bounce away.

The rubber section of the mounts does eventually degrade and will fail faster in dusty applications.

Rubber Mounts

These are simple isolating pads made of rubber which are cheap and reliable. They work well when the vibrating unit’s stroke is low.

The rubber surface is easy to clean and works well in food applications when cavities are undesirable.
