Sliding Frame Silos

Similar to the Push Floor, Schwing Bioset’s unique Sliding Frame Silo design provides for a low cost method to store a large volume of material while awaiting final disposal.  The SBI sliding frame discharge system is installed on the floor of the silo and allows for metered unloading into trucks or an SBI pump.  Biosolids are typically pumped into the silos using the proven Schwing Bioset piston pump.

Sliding frame silos serve three primary roles in wastewater treatment plants:

• Silo can be used to provide intermediate storage in the process streams enabling surges in solids production to be equalized.
• Silos can also be used for truck loading.
• Silos can be used as truck receiving stations to accept biosolids hauled in from other WWTP’s.

The Sliding Frame Silo is a simple machine consisting of either one or two hydraulic cylinders which actuate an elliptical frame across the silo floor. The frames action breaks any bridging that may occur over the extraction screw and also serves to push and pull the material towards the silo center for discharge.  The biosolids are then fed into a metering screw conveyor or twin screw feeder for discharge.
