Coil springs supporting crushing and screening equipment have to put up with a lot in life.
Not only are they expected to function reliably in often wet and corrosive environments, but also they have to cope with rapidly changing loads and sudden severe impacts.
Not surprisingly, many suffer trauma as a result. One problem is noisy coil chatter as loads change. Under constant battering, coils may also suffer spring set, or permanent compression below their original design height. This means they do not perform to their original specifications.
In the worst cases, they break. Then there is not only downtime to consider, but also maintenance workers have to get right into some of the most inaccessible entrails of industrial equipment.
“And even when they are functioning perfectly, the row produced by conventional coils can be a hazard to hearing – not to mention sanity,” says actuation and isolation specifier Simon Agar.
Mr Agar, who has 15 years experience in his field with Air Springs Supply Pty Ltd, is developing the use of quieter and more efficient actuators and isolators, including proven rubber-and-fabric Marsh Mellow springs from Firestone.
Marsh Mellows are in use world wide in applications such as shaker screens, crushing equipment, vibrating bins and other vibrating equipment used in applications including food processing, manufacturing, materials handling, quarries, mineral processing and primary product processing.
