Roller and Pneumatic Conveyors D2L Flashcards
What material characteristics is a roller conveyor best suited for?
Solid and Flat
What is the minimum number of rollers that should be in contact with the load on a roller conveyor?
3 - for roller
5 - for skate rollers
If a gravity roller conveyor is 25 feet long and requires a pitch of 1/4” per foot, what amount should the end of the rollcase be elevated by?
25 x .25 = 6.25”
True or False;
Tapered roller curves handle heavy loads more efficiently than straight roller curves
True
Which type of belt drive for roller conveyors has the advantage of varying the amount of torque available to individual rollers?
Flat Belt
What would be 3 applications where rollers on a roll conveyor should be driven by a chain.
- Dirty or Oily Environments
- Heavy Loads
- Hot Environments
What conveyor system would be used to transfer a load 90° to a chain conveyor?
Bottle Rolls
What is the purpose of a gravity roller spur?
Transfer a load to or from a main conveyor
True or False;
It is the best practice to service or repair jump rollers while they are raised, so it is easier to access the underside of the roll case.
False
- airbags lift frame, potential danger?
What condition is required in order for material to flow in a pneumatic conveying system?
Pressure Differential
What pneumatic conveyor component would wear the most?
Outside radius of pipe elbows
What component keeps pressurized air out of a hopper and meters product into the air stream of a pneumatic conveyor?
Feeder
True or False;
Air slide conveyors require very little maintenance because they have very few, if not any, moving parts.
True
What can be modified to change the displacement of a vibrating conveyor.
- Motor Speed
- Springs
- Eccentric drive
