Loading Bellows

Loading Bellows

Loading Bellows are used for 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 bellow to provide for dust removal.

Functions and Operations

Loading Bellows are suitable for continuous loading with a maximum flow rate of 250m3/h (147 cfm). At the lower end of the Loading Bellow, a special dust skirt is provided for settling on the stockpile. The equipment is available with electric or manual winch. A spigot on the header can be connected on site to an external de-dusting filter.

First the Loading Bellow is lowered from the stand-by position towards the truck skip or stockpile. As soon as the bellow outlet has reached its destination, the slack cable switch mounted outside the transmission box stops lowering of the bellow. The limit switch inside the transmission box stops both full extension and contraction of the bellow. Material loading is started by opening the silo outlet valve. Once the bellow is fully contracted, the cable limit switch inside the transmission box stops operation.

Features and Benefits

• Flexible chute in Neoprene covered by Hypalon® makes the bellow weather-proof, highly abrasion and temperature-resistant and durable
• Two lifting cables outside the material flow raise and lower the loading bellow without cable wear due to material friction and obstruction to material flow
