The Vical® feeding conveyors have several types of execution, indicated for different applications.
The fastening schemes can be multiplied according to the type of silo mouth, bin, or similar. The diagram above shows the different possible options for attaching the conveying trough.
The other diagram shows us nine possible combinations of inner linings or seals. The inner liners depend on the type of material to be conveyed. Sticky, abrasive materials require high molecular weight rubber or polyethylene liners in the chute (types BA, BV, BF); highly abrasive materials require wear plate liners, replaceable after wear (types RA, RV, RF). Materials that do not have the above characteristics can be transported in so-called light-weight chutes (types LA, LV, LF).
To eliminate the propagation of dust when extracting materials from silos or bins, the chute with seal (types LV, RV, BV) is recommended. Rubber flaps fixed on the top of the chute flaps seal the gap between the discharge mouth and the chute. A fully closed model is also available (types LF, RF, BF).
