IHC Robbins recognized the design limitations and failings in Process bin designs over twenty years ago and embarked on a development program to rectify the situation.
Today IHC Robbins manufacture a range of Mass flow process bins which are incorporated in our own packaged plants or alternatively can be custom designed and built to suit existing plants.
Process Bins are available in the following standard metre sizes but are not necessarily limited to these:
0.9, 1.2, 1.5 and 2.0m square
3.0, 4.0 and 5.0m diameter.

All bins are steeply sided and are supported on the bin base (not hung). Bins 3.0 metre and larger 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 smaller bins from 0.9 to 2.0 metres are profiled from square to rectangular. The 3.0 to 5.0 metre bins are round to rectangular.
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 however pump out systems are recommended.
Off-take nozzles are strategically positioned around each bin for DP instrumentation.
