The Spiralling Belt Elevator moves bulk solids continuously through horizontal and vertical stretches with no points of transfer.
Motor speed, material feed, and straight belt run are monitored by safety devices. The elevator is fed horizontally by a continuous conveyor. In the area of transfer, any fine material particles adhering to the belt drop into a scraper conveyor and are fed back as spillage to the main flow by a circuit conveyor.
The vertical handling section consists of the rubber belt with corrugated side walls and "flights'. This vertical section of the elevator can be slewed in the direction of discharge. Slewing through 135°C to either side is possible while moving. A control unit ensures accurate positioning of the belt to the selected point of discharge. The material is discharged from the upper horizontal section.
The Spiralling Belt Elevator can be used wherever fine-to-coarse-grained bulk solids require to be handled, horizontally and vertically, in a very confined space.
The Scooping Belt Conveyor moves bulk solids continuously on level and inclined stretches. The webs, or flights, of the corrugated and belt scoop up the material and also prevent the flow-back of fluidising powdered material.
The totally enclosed construction ensures that there is no spillage. Material adhering to the belt and moved beyond the point of discharge, immediately returned by the partitions to the feed side and received back by the upper belt. The housing of the return, and take-up units designed as a scooping trough, serves this purpose.
The Scooping Belt Conveyor is preferably used to handle wet ash. lime, cement, gypsum, ground lime, wood chips, or similar, difficult-to-handle material.
The girdle pocket elevator- elevates bulk solids continuously. The pockets are filled from inside and completely emptied inside, so that various dry materials can be handled one after the other. The gapless succession of girdle pockets prevents the loss from spillage, as this will drop without being dispersed into the pocket below.
The elevator strand as the tractive element consists of two endless, steel,-cable- reinforced rubber belts or chains with pockets attached to cross-bars arranged between them. Pocket bottoms are made of flexible, abrasion-proof rubber or metal.
The entire strand has a low dead weight, as - in the standard design - only the pocket side walls, cross-bars, and attaching elements, as well as the tension inserts of the belts are made of steel.
The strand is tensioned at the lower return unit. Drive of the girdle pocket elevator is at the top.
Suitable both for fine-grained and lumpy, sharp-edged materials such as coarse and fine ores, sinter raw mix, coke, silicon carbide, corundum, chrome ore, cullet, green and reclaimed foundry sands, pellets and other soft and burnt products, burnt lime, chemical products.
The Apron Feeder operates on principle of gravity discharge. Aprons consist of endless pivoted steel humped plates, attached to side bar chains and runs on rollers on both sides. Drive is through shaft mounted geared motor with either constant or variable speed.
Feeder is totally enclosed and provided with connection for dust extraction.
Used to extract bulk solids from bins, convey over short distance and feed to downstream process. It can be used on bulk solids with a particle size of up to 100 mm and temperatures of up to 800 Degree C.
