Conveyors

3. increasing this allows the belt to have more power
5. used to increase friction between the belt and pulley, can be sprayed, vulcanized or attached by plates
7. carries the load and protects belt from abrasion, wear, corrosion and deterioration
11. idlers that are placed under the loading zone to prevent belt damage
13. used to transmit power to the belt
14. a device that allows the discharge of material from either selected points or any point along the way of the length of the conveyor
15. rubber devices used to keep material from falling off sides of belt at loading zone
17. mesh like or grate like device to filter out different sized materials allowing finer material to flow through first and act as a cushion for larger materials
18. requires a motor for each of the two drive pulleys
21. the portion of the belt that provides strength and tension
22. a method used to removed tramp iron from material being conveyed
24. never to be used as the head pulley but allows the belt to be centered on the pulley
26. is a one-piece casting of malleable iron comprising both barrel and side bars, H class is similar but of a heavier construction
27. allows belt to carry loads of finer material
28. used with chain conveyors and correct selection is essential for a smooth and trouble-free operation
29. used to increase the arc of contact

1. conveyors that are commonly used when material must be conveyed from more than one central location for lighter less dense materials
2. has its flights formed to look like trays or pans to form a deep bed, used for large amounts of heavy or hot materials
4. idlers used to trough or flatten out a troughed belt conveyor
6. the best method to patch a belt
8. uses a snub sprocket to allow buckets to be completely inverted
9. a piece of equipment used to move material from one location to another
10. can be a variety of designs and pitches depending on the material to be conveyed
12. joining method for belt that are made by overlapping the ends of the belt over each other for at least one belt width, then fastening with elevator bolts
16. a conveyor that uses a motor, springs and a pan to convey material
19. has same pitch as the screw dimension
20. manual take up located at the tail pulley
23. used in chain conveyors when a long and heavily loaded system are required
25. also known as rollers used in belt conveyors or even on their own in some conveyors
27. pulley that uses gravity to keep belt taut
