Conveyors
Across
- 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
Down
- 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
