Figure 5.12. Bucket elevators and conveyors, (a) Spaced bucket elevator, (b) Bucket conveyor for vertical and horizontal travel, (c) Discharge of pivoted buckets on horizontal path, (d) Spaced buckets receive part of their load directly and part by scooping the bottom, (e) Continuous buckets are filled as they pass through the loading leg with a feed spout above the tail wheel, (f) Centrifugal discharge of buckets, (g) Discharge mode of continuous buckets.

CONVEYORS. Pneumatic conveyors for solids are described in Chap. 7. Other common devices for transportation include belt conveyors and bucket elevators, closed-belt conveyors with zipperlike fasteners, and various kinds of drag and flight conveyors. These all include a return leg that carries the empty belt or chain back from the discharge to the loading point. Vibrating conveyors and screw conveyors have no return leg but only operate over relatively short distances. Pneumatic conveyors also have no return leg and are not so limited as to distance of travel. Conveyors for solids are discussed in Ref. 9a.
