Jarmet pan mixer

[diyshed]

It's a 0.8 cubic metre pto machine. There is no max line stamped anywhere in it. How far do lads normally fill them up too?

Would this mix sound about right for 0.8 metres?
1500kg concrete gravel
300kg cement
120 litres of water

Sounds about right, density of your aggregate determines how much you need so would be slightly less than 1500 kg here for example.

Put a fair bit of water in before the dry parts as they take a lot of turning if dry first

I used to only fill it to the top of the rotors.
I found it used to come out a lot wetter than it looked when mixing so don't let it get too wet

Yes its annoying that there is no mark to show you where the 800 litres mark is.

Load it with 3t mini digger. It's roughly 1 bag of cement to one level bucket of ballast

If you overfill the mixer you get a wave effect when mixing that can slosh your mix out the top.
As said before add gravel and water at same time to keep mix fluid (our mixer didn't like dry mixing a batch).
Needs to be semi fluid before adding cement powder which should ensure that cement powder is thoroughly distributed though gravel and as mix dehydrates prevents slip clutch going on mixer on over torque.
We have always made mixes based on volume not weight as this ensures consistent end product regardless of how aggregate has been stored.
For info a 1 cement , 2 sand 3 aggregate mix (1:2:3) for 1 m3 mix would be 320 kg cement, 720kg sand and 1190 kg of stones but this depends on how wet sand is....

We just do it till it looks right, 6 bags of cement to 1 (ton bag) bag of ballast or 7 bags of cement if we're loading with the digger, then as wet as you want it.

i normaly use 9 ditching buckets of gravel on a 1.5tonne mini digger, think that was about 108shovels i counted once
7 bags of cement and around 8-9 buckets of water

No one has mentioned shear bolts. Standards are slipping on TFF. Very poor show indeed.

When we did a big floor for a shed, we did 6 bags per mix too, didn't faff around weighing out the ballast, just filled it up with loader.

As others have said.. make sure it's turning over as you add the ballast (slowly). We had it on a 125hp tractor and actually stopped it dead twice when was over doing it.

Worth noting that recently priced up about 10 tonne for some footings and it was cheaper to buy it in mixed than buy the raw materials... Cement is gold dust at moment

only reason i have a pan mixer is because i have plenty of free sand and gravell from the river, and its quite handy to do small areas. if im doing a large pour i just get ready mix
