Drier discharge auger

[fastfish]

need to make the discharge auger slower 2.5 inch pulley on motor do I need to increase or decrease diameter to make this happen been to two places told me different tia

 

[Lincs Lass]

Larger pulley on the auger

 

[Bob c]

the driving pulley needs to be smaller than the driven pulley


edit or its the other way round

large pulley on augur, had a 1.5 on motor and 10 inch on augur for a special job here,
later replaced with a 50--1 worm drive gearbox

the posh way would be a VFD ?? drive to give infinetly variable speed

The auger pulley is 5 inch diameter that is not changing the rpm of the motor is 1450 that is not changing as single phase the only thing I can change is the pulley on the motor 2.5 inches diameter at the moment bigger or smaller pulley

Smaller on the motor (output) will slow it down....smaller you go the less contact area you have on the belts too, as in less power to drive IYSWIM.

how much do you want to slow it down ? and how big a motor

 

[Lincs Lass]

Will a slow moving auger bung up quicker ,,they work on the principle of high speed to keep the grain moving and less load

0.75 kw not a lot just to make a mor even flow to the elevator

Not a big load dry grain and only six foot long,

Would it be better (and easier) to restrict the flow of grain into the auger?

 

[johnflimston]

Simple answer to simple question "bigger"

you can do it that way, but its not good having agur rattling away without enough grain to lubricate it.
A cheap 3 phase motor coupled to a single phase vfd is the real answer, just so simple to adjust speed to need

Single phase

 

[joe soapy]

Single phase

read the post,,, a VFD works on single phase supply and by electronic trickery gives a 3 phase output that can vary the direction and speed of a 3 phase motor
