This equipment is used to load bulk or abrasive materials in lumps such as clinker, limestone, unprocessed coal; etc. that require a particularly robust construction. They are always connected to a suitable dedusting filter with a capacity of 4000 – 8000 m3/h.Construction characteristics:
- Metal upper head with circular material feed point, one/two connection points to the dedusting filter, hoist to lift the lower head, pulleys for lower head lifting cables and electric sensor to operate the hoist;
- Metal lower head with rubber skirt to keep the unloading zone clear, creating better air suction conditions for dust extraction. An electric sensor controls the level of material for correct operation of the system;
- Extendable intermediate casing consisting a series of inner telescopic tubes in antiwear steel, in which the material to be unloaded flows, and external tubular bellows in flexible material reinforced with metal rings that connects the two heads at either end, allowing the lower head to travel a certain distance (standard value 3000 mm) so as to position itself in the correct zone of the vehicle or location to load. The space between the two tubes is solely for the passage of the dust-filled air sucked upwards by the filter;
- Electric control panel and hanging control button strip.
Note: This equipment may be powered by a vehicle or through one or more valves described under “Valves and slide gates” in Products.
