DISCHARGING AIDS

DISCHARGING AID WITH TEXTILE HOSE


In silos or tanks, a hose system consisting of special textile material is used which is permeable to air on one side. With this hose system, the stored, powdery bulk material is aerated and prepared for transport. 

The fluidised air distributed evenly over the entire cross-section ensures continual discharging and prevents core flow in the silo.

The demand for air and thus for energy is remarkably low. Every silo can be easily retrofitted with this system and adapted to any condition on site. 

Retrofitting of the approx. 110mm wide aeration hose is possible in all silo geometries. Mounting systems for all silo materials are available.

SYSTEM FUNCTIONALITY


A one-sided air permeable special textile hose is equipped with an inner, stabilising aluminium strip. For fluidisation, compressed air is conducted into the hose using a ring line installed inside or outside with a positive operating pressure of 0.5 to 0.7 bar g and an air volume of 1.0 to 1.5 Nm³/h/m².

SYSTEM ADAPTABILITY


The BEWO conveying system has demonstrated its flexibility and versatility many times over. This is demonstrated by a case study: Two bread crumb silos in a concrete bunker used as storage by Brata in Neuss proved to be particularly difficult to access.

The unusual bunker design caused frequent operational malfunctions during the conveying of the product. It was only after a “Hermanns System” discharging aid had been retrofitted and the ring line had been separated into four areas that it became possible to fluidise the bunker section by section.

DISCHARGING AIDS MADE OF POROUS SINTERED PLASTIC


The aeration equipment made of porous plastic is generally used in small tanks with a cross-section of up to 3m². This is especially important with weighed materials: The tanks are emptied down to the adhesion residue during this process.

All aeration cones can be replaced with little installation effort. It is not necessary to produce any new tanks. The porous plastic is heat resistant to 80°C.

DISCHARGING AIDS MADE OF POROUS SINTERED STAINLESS STEEL


Our aeration equipment made of porous sintered stainless steel is usually used in smaller tanks with a cross-section of up to 3m². This is especially important with weighed materials - the tanks are emptied down to the adhesion residue during this process.


All aeration cones can be replaced with little installation effort, without the need to produce any new tanks. In contrast to porous plastic, the stainless steel version is heat resistant to 200°C. This version is used for conveying abrasive raw materials. Evenly distributed strips of sintered stainless steel guarantee the optimal aeration of bulk material in silos.
