Typical Problems

18

Substances kept in bulk storage silos generallyattract moisture which eventually causes the materialto bind and adhere to the walls or form clumps,consequently resulting in blockages of the valveoutlets and build-up along the sidewalls and the baseof the vessel.

Silo Whip

The whipping head is suspended inside the silo andefficiently removes build up using an air-driven or hydraulicrotary cutter with a 360 degree rotation and an operatingdepth of up to 50m.

Cleared material simply falls to the base of the silo forextraction. The whip is controlled from the top and outsideof the silo.

Cardox Blasts

20

Cardox tubes are filled with liquid carbon dioxide. When energized bythe application of a small electrical charge, the chemical heaterinstantly converts the liquid carbon dioxide to a gas expanding the CO2

and building up pressure until the rapture disk at the end of the tubebursts, this releases the CO2 now 600 times it original volume. Aspecial discharge nozzle is employed.
