Truss Frame Belt Conveyor for Bulk Materials

This is a typical trough style belt conveyor with a truss style frame that allows spanning long distances between support points. For lower profile design, a channel is used in lieu of a truss which is called a channel frame belt conveyor. Belt is supported on troughing idlers.

Slider Bed Conveyor for Bulk Materials

In this case the conveyor belt slides over a formed steel bed lined with UHMW instead of being supported by troughing idler rollers.  Good for high impact conveyor loads and moderate head loads.  This conveyor with high sides is economical for conveying or feeding high material depths of light or medium bulk density material.  V notched conveyor allows conveying up a higher incline

 

High Angle Conveyors 

 

Here are conveyors used to convey bulk materials up steep inclines.  Some use cleats.  The drawback of cleats is that there is “material carryback” that remains on the belt after the discharge point.  The carryback material often accumulates in piles on the floor requiring frequent housekeeping.

 

Typical Pocket Belt or Flexible Sidewall Steep Inlcine Conveyor

 

Solutions to Carryback Problem:

Belt Scraper(s) at head pulley—Works well on smooth belts only.  Better with vulcanized rubber or plastic splice and not as effective with metal “Alligator Splice”.  NOT an option with high incline cleat conveyors.  V notched belt can use a rotary brush.

To Remove Carryback on a Flexowall Conveyor:

Belt Thumpers which are a rotating roller slapping on the back of the belt provide only a partial solution.

Air Knife can further assist in removal of carryback, but one will need to add dust collection to deal with the airborne material.

A good option for using a smooth belt conveyor in high incline application switch CAN be cleaned by a belt scrapers  is a Snake Conveyor which is essentially a Sandwich Belt that places one troughing conveyor over top of another to sandwich material such a coal, sludge, or wood chips in order to convey up a VERY steep incline.

Example of Sandwich Belt Conveyor

Sandwich Belt Conveyors usually cost well over $100K and therefore are justified where space is a premium, the convey rates are fairly high, a high degree of reliability is desired, and/or the product has high value, handling characteristics are challenging- sticky or dusty.   Many times these are Port Facility Conveyors or High Production High Angle Conveyors known as a HAC.
