HP requirement of whisk type agitators

JohnBoy

Hi,

Most pump type agitators start at around 80hp power requirement.

How do the older style straight propellor agitators compare? would they be around the same, more, or less hungry?


Any hope of running one off 60hp?

don't know about hp but those things are useless unless you have a guiderail with a box at the bottom for the whisk to sit into

if you have this arrangement then everything gets pulled through the whisk and it can't flow back, this is quite a good system

stick one of those whisks into an open pit which is anyway thick forget it, it agitates an area the size of the bedroom if you are lucky

not a bad machine if used in conjunction with a slurry pump, the slurry pump pushes the stuff around and the whisk chops up the big thick lumps

60hp drive one? depends on the model I think a medium size one yes

Not sure, run mine on 100hp, when a big lump comes round it groans but actually stirring takes little effort. Great for open tanks!

Exactly, I could have taken bales off the crust this year, put the two together and got it in about 2 hrs, would be still there with either one on its own. One passed it the the other, great job. Usually the whisk works on its own though.

Ya 60 hp should do it, depends on how much water you have in the tank though:D Pitch on the propeller is the big issue.

It also will only move about 30 ft of tank, so you would need a manhole/agitation point every 3 bays of a shed. However if they are built in to a double tank where the slurry moves around in a big circle they are in theory supposed to work well, only trouble is the crust won't move.

we have two of them the older small one runs no problem on 80 hp, 60 hp would manage it.
the bigger one really needs a min of 100 hp even 120 to be comfortable.

think it comes down to size of propeller, the more of a bite the more hp required.

if you are buying one, make sure it has a reversible gear box, esp if used in circuit type tanks, the push/pull effect of changing direction helps pull in crust.
we got ours at the time of the grant, and found it impossible to get one with reverse gear box, ended up getting the agitator custom made

We used to run one on an old mf65. It worked it with ease.

keep going

we think whisks are fine for open pits but not much good under slats-too awkard to get in and will only do30 ft.used to drive one with a 165 no problem which is 62 hp

Good to hear folks.

I know they're not as good as the pump, but have a drive in, open pit which the contractors are to agitate as there's nowhere to drop down a pump type machine.

One to add to the list, man it's getting long

I have one for sale if you are interested

Probably be the new year at the earliest before we do anything, but if you still have it then......

Would a 55 horse power tractor power a whisk agitator? Anyone know?

yes no problem,if it cant you wont suck it up either

Thanks but,what do you mean by "I won't suck it up either". Are the whisk agitators hard to get them down into a slatted unit?

Waste of time in a slatted tank. These were designed for old open tanks where they could be lifted and moved around.

But could you get them into a slatted tank - surely if you could get them in to the slatted tank, then they aren't a waste of time.
