Bulk Tanker Loading (Filling) Bellows are products used to load powder fluids from storage silos into bulk tankers. These powder fluids include materials such as cement, lime, powdered sugar, flour, calcite, ash, carbon black, bran, etc.
Bulk tanker loading (filling) bellows are products used to fill bulk tankers with powder fluids from storage silos. These powder fluids include materials such as cement, lime, powdered sugar, flour, calcite, ash, carbon black, bran, etc.
When the vehicle to be filled approaches under the silo, the bulk tanker loading bellows (also known as a telescopic chute or filling chute) is extended downward via the hand control. Because this extension is telescopic, the product is also referred to as a telescopic chute or telescopic tanker filling bellows.
The cones located inside the double-walled fabric of the bulk tanker filling bellows nest into each other to create a telescopic geometry, allowing the structure to extend and retract. The internal cone system, which can be manufactured from carbon steel (DKP), AISI (Stainless), or Hardox, protects the double-walled fabric and slows down the powder or granular product during loading. In this way, the material is discharged into the tanker without creating dust. The telescopic system is controlled by limiting its maximum and minimum lengths via turn-counter sensors. The minimum and maximum lengths are determined according to field conditions, and the open/closed lengths are adjusted before shipping. If a longer extended length is desired, it can be easily modified thanks to our modular design.
In facilities without a central dust collection system (filtration system), local filters can be manufactured specifically to suction the dust emitted from the bulk tanker filling bellows. Thanks to the jet-pulse cleaning system in these filters, the dusty air is separated by the filter cartridges, and the accumulated dust is recovered. This prevents material waste through dusting and avoids environmental pollution. You can contact us for detailed information regarding filtration systems.
The bulk tanker loading-filling bellows ensures that bulk dry powder, granules, and granular materials coming from storage silos or mechanical-pneumatic conveying systems are loaded into bulk tankers and closed-body vehicles without dust emission.
Thanks to its flexible-telescopic structure, the loading bellows extends vertically until it seats on the loading inlet of the filling vehicle. Once the conical part of the filling bellows seats on the tanker inlet, the cable slack sensor is activated and stops the bellows. Additionally, the user can stop the bellows at any desired position. The flexible polyurethane coating on the conical mouth of the loading bellows ensures dust-tightness at the filling point. Subsequently, the flow control valves at the filling inlet open, and the material is filled into the tanker. Once the material level is detected by the paddle, motorized, or vibrating level sensor at the discharge mouth of the loading bellows, the filling valve (butterfly, slide, or rotary valve) cuts off the material flow. Dust particles generated during filling are managed in two ways as explained below.
