Grey Iron Foundry

Foundry operations produce a variety of byproducts—baghouse dust, grinding residue, dusts from molding and handling, and spent sand. A large manufacturer enlisted DustMASTER to develop a solution for managing all of their dusts from   collectors throughout the plant, which are transported by a pneumatic system into a single storage silo.

DustMASTER specified a 60 TPH Series I mixing system, which is fabricated with components such as a Turbin style pan mixer with a hydraulically operated discharge door, material weigh hopper, metered water system and control with programmable controller which includes 100% manual override and load cell readout.

We conducted manual testing of the material at our test facility as well as on site at the foundry to stabilize the dust, which included cupola dust at 500°F and general foundry dust. We monitored and recorded the moisture percentage added in by weight, which resulted in a final product that was fully suitable for landfill disposal. It was then run for an additional five minutes, for a total of seven minutes, with no visible change in product consistency. This demonstrated the efficacy of our batch mixing system for foundry industry applications.

The Turbin mixer is installed next to the silo, and continuously mixes the combined waste and discharges it into a roll-off box. Operators then pick up the full box and transport it to the company-owned landfill.
