MATCON USA, INC.

Matcon-Buls Intermediate Bulk Container (IBC) system discharges materials from portable bulk storage containers. Using Matcon's patented discharger/valve principle, each IBC has an "in-bin" cone valve at its discharge. When the IBC is placed on its discharge station, the inverted cone mates with a probe within the station. The probe pneumatically raises the cone into the material and vibrates it, causing the material to break up and flow through the annular gap created by the lifted cone. Varying the cone's height and lift time allows metering the material. Weigh frames and controllers are available for accurate batching or continuous feeding. Because the cone and probe create a dust-tight seal during operation, the IBCs can be filled, transported and discharged with no dust contamination. Partially filled IBCs can be removed from the station with total containment of product. Containers constructed of stainless or mild steel or polyethylene. Capacities to 100 cu ft available.
