Steel bins, hoppers and chutes – built for flow, wear and load

The shape of a hopper decides how a bulk solid flows. In mass flow the whole contents move when the outlet opens – first in, first out, no dead zones – which needs steep, smooth walls. In funnel flow material flows through a central channel while the rest stays still – a simpler, lower bin, suitable for free-flowing, non-degrading materials.

Wall angle, outlet size and liner are selected from the flow properties of the material. World Steel fabricates to your bin designer's geometry or prepares the detailed design when the flow data and loads are available, with stiffeners, ring beams and supports sized for the pressures that bulk solids exert on the walls.
