Typical conveyor problems

Scrapers not functioning Poor v plough installation Secondary scrapers not efficient

Poor chute maintenance preformed Poor chute maintenance preformed Liners cutting conveyor

List of recommendation solutions

1. Misaligned: Idlers, idler frames and conveyor pulleys not aligned: align center and level
2. Conveyor structure: Conveyor frame or structure not straight or aligned in affected areas: align structure.
3. Idler frame or idler frame support structure not centered: readjust frames

4. Build-up of material on idlers: Stuck idlers replace/ free idlers and improve idler and scraper maintenance.

5. Build-up of material on idlers, - remove source of spillage improve maintenance on idlers and scrapers.

6. Belt Splice or clip joint not square: Belt Joint/ splice not made squarely redo splice or clip joint by ensure centre line is
used, if still incorrect fit insert in are, it can be conveyor have a dog leg in the conveyor.

7. Bowed belt: when conveyor is new this condition should disappear during initial start-up of conveyor while belt is settling ,
it may happen belt have been manufactured incorrectly and portion will require replacement, conveyor will continue
running out on the same section of the belt while other will track correctly

8. Off centre loading or poor loading: check if there is nothing stuck in chute, adjust chute to ensure proper loading in centre
of conveyor. Material discharging must be as close as possible to conv speed product is discharging from the feed point

9. Conveyor Slipping on drive pulley: Check lagging if worn replace, if screw take up then check belt tension, check if conv is
stuck, check if any work has been performed like drive snub pulley been replaced which could have changed angle of
wrap on unit. Do not ad mass to counterweight if existing installation, this is detrimental to conveyor and pulley laggings.

10. Material Spillage and build up: improve lodging and transfer conditions ensure scrapers is in working condition improve
skirting maintenance to prevent spillage, check for excessive water and rectify

11. Bolt heads protruding above lagging : tighten bolts and lower angle scraper( no pulleys in use which is bolted in position
at WVK)

12. Tension to high: increase speed, same tonnage and same speed: Reduce friction with better maintenance and
replacement of damage idlers. Decrease tension by increasing arc of contact or go to lagged pulley, take up tension to
high or mass to heavy

13. Skirtings improper adjustments or wrong type of material used: adjust skirt board supports to minimum 25mm between
metal and belt with gap increasing in direction of belt travel , use skirt board rubber and not conveyor belt

14. Load Jam in chute: check design to transfer correct size of material and volume. Check chute is not blocked with rail liners
or welded angle irons by artisans to form dead boxes, Check dead box design

15. Material hanging up in or under chute: Improve loading to reduce spillage, install correct lining material , check chute
discharge angle, remove all none designed dead boxes in chute

16. Impact of material on belt: reduce impact on belt by improving chute discharge point, install impact idlers or impact bed

17. Material trapped between belt and pulley: Install scrapers on return conveyor to prevent spillage from lodging in conveyors

18. Belt edges folding up on structures: Same corrections as point 1-2-3, install belt misalignment switches, ensure correct
width belt is being used.

19. Dirty stuck or misalign rolls : repair points of spillage like chutes, install and maintain Scrappers and pulley laggings, check
condition of belt top cover

20. Top and bottom cover: if incorrect spec replace wit correct belt

21. Spilled grease or oil: over lubrication of equipment, improve house keeping

22. Wrong type of fastener used Clip joint)

23. Heat or chemical damage: use belt designed for specific condition.

24. Faster plates too long for pulley size: replace with smaller fasteners , increase pulley size

List of recommendation solutions (Continues)

25. Improve transition between troughed belt and terminal pulleys. Adjust transition in accordance with manufacturing
specifications

26. Severe convex (hump) vertical curve: decrease idler spacing in curve, increase curve radius
27. Excessive forward curve tilt of trough rolls: reduce forward tilt of idlers to no more than 2 degrees from vertical
28. Excess gap between idler rolls: replace idlers, replace with heavier belting
29. Insufficient transverse stiffness: replaced with proper belt
30. Pulleys to small: Replace with larger diameter pulleys
31. Counterweight to light: add counterweight mass or tight screw tensioners to calculated value
32. Counterweight to light: remove counterweight mass or tight screw tensioners to calculated value
33. Pulley lagging worn ; replace pulley lagging.
34. Insufficient traction between belt and pulley: Lag drive pulley: increase belt wrap: install belt scrapers where required
35. System under belted: recalculate belt tensions and select proper belt
36. Excessive sag between idlers causing load to work and shuffle on belt as it passes over idlers: increase belt tension if

necessary, ifunnecessary reduce idler frame spacing
37. Improper storage or handling: refer to manufacturer’s specification for proper storage or handling instructions.
38. Belt improperly spliced: re splice correctly.
39. Belt running of centre around tail pulley and through the loading area, check if splice or portion of conveyor running out

before installing training idler on the return before tail pulley

List of recommendation solutions (Continues)

40. Belt running against structure; train conveyor by knocking idler or lifting frames to cater for camber if still
unsuccessful install training idlers in the area where running against structure occurs.

41. Improper belt installation causing apparent excessive belt stretch: pull belt through counterweight with a
tension equal to at least empty running tension: run belt in with mechanical fasteners

42. Improper initial positioning of counter weight in its carriage causing apparent excessive belt stretch : pull
belt through counterweight with a tension equal to at least empty running tension, run belt in with
mechanical fasteners

43. Insufficient counterweight travel: redesign counterweight travel distance or install insert on conveyor

44. Structure not level: Level structure

45. Top cover cuts and punctures allows fines to work under cover and cut cover away from carcass: make
spot repair with vulcanize or self-catering repair material

46. Worn edges: Retrain conveyors running into structures

47. Interference from belt scrapers: adjust belt scrapers

48. Tension too high for fasteners: use vulcanised splice

49. Belt carcass to light: select stronger belt keeps on tearing

50. Belt misalignment: see training recommendations

51. Variations in nature and formation of load: use notched chute to keep load peak in exact center of belt

52. Belt not making good contact with all idlers: adjust height so all idlers contact belt

53. Sharp edges of material or tramp iron coming in contact with cover: use jingle bars .Impact idlers and
magnetic removal equipment
