IHC Robbins recognized the design limitations and failings in Surge bin designs over twenty years ago and embarked on a development program to rectify the situation.
With the assistance of the Woolongong university in NSW, IHC Robbins modelled a variety of different design shapes, until the optimum shape was discovered.
Today IHC Robbins manufacture a range of Mass flow Surge bins which are incorporated in our own packaged plants or alternatively can be custom designed and built to suit existing plants.
Surge Bins are available in the following standard sizes but are not necessarily limited to these:
7.0, 9.0, 12.0 and 15.0m diameter.

All Surge bins are steeply sided, and supported on the bin base (not hung). All surge bins are supported additionally by pairs of braced columns. These are equi-spaced around the top perimeter of the bin. These can support equipment loads located above the bin and also resist any dynamic loading the bin may be subjected to.
The 7.0 & 9.0 metre surge bins are round to rectangular, while the 9.0 to 15.0 metre bins are round to polygon shape to aid transportation.
The unique bin profiles prevent stable arches from forming within the bin consequently hang ups and surging within are absent and hence they mass flow.
The overflow launder is located in board and is partially supported by bridging beams located at the bin top. These can also be used to support a boil box, which can be supplied as an optional extra.
Bin suction and injection water manifolds are horizontal spears designs and are rubber or urethane lined both inside and out. Dump hatches are provided or alternatively; pump-out systems can be custom designed. Off take nozzles are strategically positioned around each bin for DP instrumentation.
