Open truck loading with powders and bulk solids
Loading bellows / telescopic chutes
ZH Loading Bellows ensure efficient, dust controlled discharging of dry, dusty bulk solids into open lorries or trucks.
The loading spouts are provided with inner tapered cones to contain the flow of material and an outer bellows to provide for dust removal.
First the Loading Bellows is lowered from stand-by position towards the truck bed or stockpile. As soon as the bellows outlet touches the surface, a slack cable switch mounted outside the transmission box stops lowering of the bellows.
A limit switch inside the transmission box stops both full extension and contraction of the bellows. Material loading starts by opening the silo outlet valve.
Once the bellows is fully contracted, the cable limit switch inside the transmission box stops operating.
Loading bellows / telescopic chutes with integrated dust filter
BELLOJET ZC Loading Bellows are used for efficient dust-free discharging of dry, dusty bulk solids into open lorries/trucks.
The spouts are provided with inner tapered cones to contain the flow of material and an outer double bellows to provide for dust removal.
First the Loading Bellows is lowered from stand-by position towards the truck bed. As soon as the bellows outlet feet touch the bed, a slack cable switch mounted outside the transmission box stops lowering of the bellows. The limit switch inside the transmission box stops both full extension and contraction of the bellows. Material loading starts by opening the silo outlet valve.
During filling of the truck the filter fan continuously sucks dust through the external bellows into the integrated filter cartridges in the upper section of the unit exhausting excess air. A level sensor mounted under the dust skirt makes the loading bellows lift progressively maintaining the skirt constantly in contact with the stockpile. Contraction of the bellows back to stand-by position is started by the operator via remote control. Once the bellows is fully contracted, the cable limit switch inside the transmission box stops operation. The preset after shut-down cleaning cycle now provides for additional pulse-jet cleaning of the filter cartridges for another ten minutes.
Loading bellows / telescopic chutes for large capacities
ZQ Loading Bellows are used for efficient discharging of powders or granular materials into ship or barge holds, or open stockpiles.
ZQ Loading Bellows are equipped with internal cones for perfect channelling of the material flow and external bellows for dust extraction.
ZQ Loading Bellows are suitable for high capacities and dust-free loading of ships, barges or stockpiles.
Bellows retraction is controlled by an electric winch.
The unit can be connected to a central dust collector on site via a lateral flanged spigot in the upper head.
Loading bellows positioner
The TR Loading Bellows Positioner moves loading bellows horizontally when loading trucks or rail cars.
The driver can stop the vehicle in the designated loading area without having to worry about being in the centre of the loading area.
The TR Loading Bellows Positioner consists of a support frame structure with an inlet connecting flange of 300 mm (22”) diameter positioned in its centre.
The frame structure supports a motor-driven hopper underneath, which runs on four wheels on tracks in one-axis horizontal direction.
The hopper is provided with a row of nylon brushes all around the inlet edge. The brushes are pressed against the cover acting as a seal against dust leakage.
