TURBIN MIXER PREPARES MATERIAL FOR FINAL DISPOSAL.
Waste-to-energy processors are helping to reduce reliance on landfill sites. But they still have a disposal problem: fly ash from waste incineration, which can contain toxins that require safe handling. An industry customer asked DustMASTER to design a system for processing WTE fly ash with water to achieve a safe product for landfill disposal.
DustMASTER conducted tests on the material using our 40TPH Series II base unit. The system includes a Turbin style pan mixer with a hydraulically operated discharge door, metered water system and control with a programmable controller which includes 100% manual override and load cell readout. Manual tests of mixing the material, monitoring and recording the added moisture percentage proved the suitability of the system. The lifting and rolling action of the mixer paddles quickly produces balls of material formed with enough moisture to hold together.
In the actual installation, the Turbin mixer is mounted directly underneath the silo storing the fly ash. The final product is dust free, with 18% water addition and a 60-second cycle time. The WTE fly ash is then acceptable for transport and landfill disposal.
