Loss in Silo Capacity?

Whether it be Cement, Clinker, Slag, Coal, Raw Meal, Soda Ash Or Clay, silos are prone to developing dead material, which is both wasteful of capacity and misleading for inventories.

It is imperative, that silo are always kept at optimum storage capacity to maintain the smooth, continued operation of production lines, overall plant effectiveness and profitability.

Typical problems include cone build-up of hardened or moist material as well as material chunks blocking the flow of material. This article explores two state of the art, safe, hygienic, economical and fast methods of silo cleaning. Both of these silo cleaning methods don’t involve any human entry into the silos, which are classified as confined spaces. 

Cardox Blasting:

Air and CO2 Liquid filled tubes that release a high pressure wave in a concentrated blast. Cardox Blasting is mainly used wherever build up cannot be reached by equipment from above the silo or from underneath at the cones. Sockets are welded onto the structure from the outside shell (steel or concrete) and the tubes are placed into the socket through an opening made in the structure.

In other cases blasting may be done from the top of the silo. This entails lowering the tube safely onto the blocked surface where blasting is required.

Silo Whip:

Hydraulic powered rotating head with knuckled chains attached rotates within the silo from a fixed point on top of the Silo. This method can only be used on the roof through an opening of 450cmX450cm square of the silo as it requires anchoring points, point of entry and room to maneuver. This is predominantly used on silos that have dead material lying on the side walls of the silo, taking up material capacity for the silo and reducing your silos total capacity. 16-60 Meters High and 10-15 Meters wide inside diameter.
