Sodimate’s patented mechancial silo unloader features a vertical spindle fitted with flexible blades to ensure the mechanical discharge of powders from silos, rigid bins and hoppers. The unloader rotates within the container bottom to prevent non-flowing materials from jamming, bridging, compacting or rat holing as seen with vibration and fluidization systems. The mechanical silo unloader was specifically designed for difficult dry chemicals such as lime, soda ash, Trona and PAC. The discharger can also integrate up to four precise volumetric screw feeders. Each screw feeder is totally independent and can feed up to 15,000lb/hr with different lengths and throughput variations.
