don't expexct miracles but it will clean the metal surfaces...multiple applications may be required...

good luck...wish I had some similar old hardware for making a mixer myself...

"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!"

Awww!....You missed all the fun!

I inherited and old gas operated little mixer that was all full of dried concrete or mortor when I got it . i put on and electric motor, I put some pieces of 3" x 3" x1" steel I had laying around took it as far from the shop as I could and let it run for a few hours
nice and clean inside had to do a little heat treating to get the fins straight again but it worked LOL

I really enjoyed the dynomite part of that dirty jobs episode was a wee bit hard on the drum
but it sure was clean

Maybe a pnuematic chisel will do the trick? Worth a try anyway. Like already suggested, I would wear safty goggles, and earplugs and hearing protector muffs as well. Good luck!

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....


3. Rubber scrubbers are all but gone.. It appears to have had rubber pads from the mixxing arms to the walls--



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..

From these descriptions, its sounds like a mortar mixer to me. Concrete mixers have fixed flights to the drum and the circular drum rotates. Mortar mixers, the drum doesn't spin, the flights do. My father was a mason so I know the difference. Hope this helps.

I have been selling and repairing Mortar Mixers for 8 years. I'm also a Stone Equipment and Multiquip dealer. I have cleaned many many mixers. I use an air chisel with a flat tipped punch for most of the work. As stated, if you can vibrate the metal the mortar fractures and breaks. Some hammer work is nessary too.
The biggest problem is the bearings and seals. They are why most mixers fail. When the parts fail then someone will keep using the machine causing other parts to fail like shafts and gears.
Rubber mud flaps work good for paddle rubbers. You can cut then with razor knife.
The pics show what happens when seals fail and the machine keeps running.

Stimw,
You reply could not have been more timely!!!
I just walked down the trail to the mixer and it is a Stone Construction Equipment model 650PM..
And it was modified to run on a PTO.

Below are 2 pics---
As you can see it has been sitting in the weeds for awhile..
I had pulled it out about 7 months ago, but stuff has already grown around it again..

It looks rough. but it may be salvagable.

there was a PTO shaft in the barn that looked out of place until I saw how the connection was..

I'm gonna go down with the tractor and get it Tue or Wed based on the weather.

now that I realize it was a "special" build... I am little concerned about PTO damage.. Gonna go and get some shear pins for the PTO connection.

Time will tell..
Once it's up on the forks and can get better pics, I'll post more..


later,
J

Muriatic acid is a diluted Hydrochloric Acid. I used to pour some into a bucket, dilute w/ water, and brush it onto Mack trucks used to transport bulk loads of cement to clean off the adhered dust.

Wear eye protection and chem resistant gloves.

I used to work next door to a Redi Mix plant and you would see one of the mixers sitting there turning w/ a bunch of gravel inside for an entire afternoon. I guess their Teamsters were too well paid to chip out the buildup...
