MS Conveyor Systems Certification- Mechanical Installation
1. What is the primary purpose of a belt splice in a conveyor system?
A) To increase belt tension
B) To join two ends of a conveyor belt to form a continuous loop
C) To clean the belt
D) To track the belt
Rationale: A belt splice connects the ends of a conveyor belt, creating an endless loop for
continuous operation.
2. Which type of belt splice is considered the strongest and most durable?
A) Mechanical fastener splice
B) Vulcanized splice
C) Cold glue splice
D) Stapled splice
Rationale: Vulcanized splices use heat and pressure to fuse the belt ends, providing
superior strength and durability.
3. What is the primary purpose of a primary belt cleaner?
A) To remove fine material from the belt
B) To remove bulk material from the belt immediately after discharge
C) To track the belt
D) To tension the belt
Rationale: Primary belt cleaners are installed at the head pulley to remove the majority of
material that adheres to the belt after discharge.
,4. What is the primary purpose of a secondary belt cleaner?
A) To remove fine material remaining on the belt after primary cleaning
B) To remove bulk material
C) To track the belt
D) To tension the belt
Rationale: Secondary cleaners are positioned further along the return belt to remove fine
particles that the primary cleaner missed.
5. Which type of pulley is designed to shed material and prevent buildup?
A) Flat pulley
B) Wing pulley
C) Crowned pulley
D) Lagged pulley
Rationale: Wing pulleys have fins or wings that allow material to fall away, preventing
buildup that can cause belt misalignment.
6. What is the primary purpose of a crowned pulley?
A) To increase belt tension
B) To help center the belt and prevent mistracking
C) To clean the belt
D) To increase belt speed
Rationale: A crowned pulley has a slightly convex surface that encourages the belt to
center itself, reducing mistracking.
7. Which type of idler is specifically designed to help train the belt and correct
misalignment?
A) Carrying idler
B) Return idler
,C) Training idler
D) Impact idler
Rationale: Training idlers are angled or have a pivoting mechanism to steer the belt back
to center when it starts to drift.
8. What is the primary function of a transition idler?
A) To support the belt at the loading point
B) To gradually change the belt from flat to troughed shape near the pulley
C) To clean the belt
D) To track the belt
Rationale: Transition idlers are placed near the head and tail pulleys to smoothly
transition the belt from a flat profile to a troughed profile, reducing stress.
9. What is the primary purpose of a gravity take-up system?
A) To increase belt speed
B) To maintain constant belt tension using a weighted counterweight
C) To clean the belt
D) To track the belt
Rationale: Gravity take-up uses a weighted pulley to automatically maintain consistent
tension as the belt stretches or contracts.
10. What is the primary purpose of a screw take-up system?
A) To maintain constant tension automatically
B) To manually adjust belt tension using a threaded rod
C) To clean the belt
D) To track the belt
Rationale: Screw take-up requires manual adjustment to increase or decrease belt tension,
typically used on shorter conveyors.
, 11. Which drive arrangement uses two pulleys to increase the angle of wrap and
traction?
A) Single pulley drive
B) Dual pulley drive
C) Tandem drive
D) Gravity drive
Rationale: A dual pulley drive uses two drive pulleys to increase the contact area between
the belt and pulleys, improving traction.
12. What is the primary purpose of a backstop on an inclined conveyor?
A) To increase belt speed
B) To prevent the conveyor from reversing direction when power is lost
C) To clean the belt
D) To track the belt
Rationale: A backstop (holdback) allows the conveyor to run forward but prevents it from
rolling backward under load when power is interrupted.
13. What is the primary purpose of a brake on an inclined conveyor?
A) To prevent reverse motion
B) To stop the conveyor and hold it in position
C) To increase belt speed
D) To clean the belt
Rationale: A brake is used to actively stop the conveyor and hold it stationary, especially
on steep inclines where a backstop alone may not suffice.
14. Which safety device is designed to stop the conveyor if the belt moves too far
to one side?
