Mortar / Concrete mixer cleanup..

[RadarTech]

hey folks,
I saw a thread here about a concrete mixer and it reminded me...
Down on the old logging road on our property there is an ancient mixer.
Right now, I can't remember if the tub was the rotating element or the arms. Which will tell me which kind of mixer it really is.... After comparing it to northern tool and other diminsions for mixers, it looks to be in the 8-10 cubic foot range.

It is setup for a 3PH, and has 3 problems I see from a quick review...

1. PTO shaft is missing
2. caked and dried mix inside
3. Rubber scrubbers are all but gone.. It appears to have had rubber pads from the mixxing arms to the walls--

It has been sitting there for at least 10 years..

I think if we can get the caked mix out that it will work fine..
BUT --- How do you remove the caked concrete?.mortar Is this just hammer time? or is there a way to do it?
Some of it looks like it could be 2 inches thick!!!

for the PTO shaft- I need to look at that again alot closer....

For the rubber scrubbers-- looks like an old tire could be cut and put there...
a place in town sells old tires from $5 and up.. mabye a job for the sawsall..



the big question here is-- is there a way to remove the concrete mix besides beating it with a hammer?


Later,

Sounds like a lot of hand work no matter how you look at it. Possibly an electric chipping hammer would help out with the bulk of concrete removal.
As far as the rubber on the paddles, I'd suggest cutting them from an old truck mud flap. You'll find that cutting into a tire is no fun. Sawzall or not, the steel belts and the reinforcement in the sidewalls might be a large pain.

I'm semi-retired and drive a ready-mix concrete truck in the summer. At least once a season we have to climb inside the drums on our trucks and remove the hardened concrete. We use hammers, chisels, an 8 lb. mall (where there's room to swing it), but mostly an air chisel. It comes off better if you can hit bare metal on the paddles and set up a vibration in them, or you can get a chisel started between the steel and the concrete. It's real easy to get the chisel jammed, so watch that. I find if you beat against the concrete itself, it just comes off in little flakes, but if you can get at the steel it will come off in bigger chunks.

The electric chipping hammer mentioned by JJZ 109 should work.

Hearing and breathing protection are mandatory.

It's a noisy, dirty job but it has to be done. Myself, I prefer to wash it out today rather than hammer it out tomorrow.

Good luck with it.

I also drove ready mix truck part time for a few summers. Fortunately, I was at my real job and not there in the off season when the other boys got the job of chipping out the drums!

I was hoping for a magic concrete eating solution!
ok- yeah I know no such thing..
Let's see how hard this will be...

I'll get a picture tomorrow...
Thanks for the advice...

Later,

Watch the episode of Dirty Jobs - Termite Contoller - Concrete spreader, termite exterminator, concrete truck cleaner

It's very easy - get someone else to do it!

once you get the bulk of the mortar out of the mixer you can clean the drum with muriatic acid.

yes any place that sells masony supplies should cary it...it can be used full strength but the fumes are very caustic...do not use in enclosed spaces. stay up wind and wear eye protection.
