My mean was 1 kg is there now.

Pliers really don't work :oops:

I heated some batteries. they explode with strong voice. I can not do this process here

Do not heat mercury containing batteries if you value your life.

Then forget herb crusher altogether.
What you can use is small shredder with bottom screen with holes smaller than smallest battery like this one:

Few videos of that shredder in action:

You will need to install screen on bottom so not shredded batteries will not fall out only when they are done. You can use it powering it by hand and when you make more from your batteries invest in small motor.

That is very interesting but I don't think I can buy from this site and ship to my country
I must go search in Alibaba maybe I can find mini shredder there
 
Nope. You are not going to find anything like that on alibaba.
Did you asked them if they will ship it to you or not?
Thinking cant solve your problem you need to act so send them email and find out. It is certainly cheaper and much better than herb crusher you thought about.
If they will not want to ship it then build your own.
All files needed complete manual are available, you can have all parts made locally and assemble it yourself. You may not need this big but I am sure it can be scaled down.
Plans and manual:

I don't ask them but I know they can ship for me :?
Thank you very much
I think I must start my work whit pliers and soon start to build a small shredder for own work.
 
You can build a cheap hammer mill from scrap chains and an old motor if you have somebody who can cut and weld pretty good. I built one a long time ago for about $100 and the majority of that was for a used trade day gas motor and the cost of the welding rods. Find a scrap yard and raid it for what you need. Gas would probably be cheaper and more reliable considering your location. If your going to do this their is no way around it. I've done a few tons of this materials and you aren't going to cut corners or find a better way that hasn't already be tried.

Small silver batteries envelope is stainless steel. Best to digest in AR - very quick reaction. Must have a good hood! Remember there's also zinc in there. The melting with sodium carbonate is converting silver chloride to silver. Big batteries may contain cooling spirals made of copper - in this case the technology changes a bit.

You can pyrolyze the batteries, then smelt them to get the silver. How much batteries?

Are you for real Kevin?
Why would anyone advocate incineration of mercury containing batteries?
Never put battery in fire as it will explode and exploding battery releasing mercury vapors is really something insane.

As you can read in my post, I suggested pyrolysis which supposely condense the smokes and re burn the excessive smoke from condenser.

I never proposed incineration, plus they have to be tested if pyrolysis follow by smelting is chosen.
 
This is not personal attack or something aimed on you or anybody here but simple truth is that none of the members I know does have pyrolysis unit which is true to its name. Not even you Kevin. What you do is incineration, you just channel smoke back to fire so it is less polluting but still incineration.
You may get away with what you use in your country, maybe OP too but I can guarantee you that if anyone try to operate anything you do use with batteries containing mercury the way you proposed, in for example EU or USA, all hell would break loose. Not to mention obvious health hazards.
I cant imagine how one is going to test 300 kilograms of batteries to sort them out before processing to figure out which does contain mercury. According to wiki "Until recently, all silver oxide batteries contained up to 0.2% mercury" so I would guess the possibility of encountering mercury is quite large.
 
One of my battery clients has built a catalog list going back to the 1970's of battery types and uses optical sorting like this but a little different. He has a + 99 % success rate for sorting by types for silver and non silver as well as mercury. After sorting they go through a very high induction field to open them up and the across the screens to separate the powder from the shells which are then also sold as scrap. Total cost of the induction unit and sorter was close to $50,000 but he does about 2 tons a week.

Thanks
Build a hammer mill is very easier and cheaper than shredder and there is some videos in YouTube that help me :) . They add chains instead of blades. :shock: Does it work for batteries ?

Edit:
These hammer mills use for herbs and wheat here. So if I buy one of them and add chain instead of blades and change holes bigger it works for me. Right?

Why this blade doesn't work for batteries but chain work ?
 
0.2% is 2 kilos per ton, or 0.6-1 kg per year if you process 300-500 kg.

If you incinerate then it will go up with the smoke and if you crush and dissolve it will follow the silver or the waste water. In any case it's vital to control it so you don't poison your neighborhood.

Here we go again.
IT WILL WORK. Blades or chains whatever. I am using a coffee grinder for incinerated IC chips and it works like charm. The real question here is: FOR HOW LONG? I tend to go through one grinder for roughly every 15 kilogrammes of IC chips.
In case you still don't understand then just think about what grain mill or herb mill mean and how effectively and for how long it will perform as desired with steel instead of herbs and grain. So if you plan on doing it for some time and in some quantities then buy or build proper equipment. It may look expensive but you will save money in long term.
 
70 percent of process has been complete
I buy a 2 hp motor with 3000 rpm now need to make a blade

Hi Palladium
Can you give me some instructions for making blade ?

As you know batteries are very small
If there is a gap ( for example 5 cm ) between mill and blades can it crush batteries ?
I can not make blade with small gap. :?

Good morning sir. Sorry for the delay. The first hammer i used before i built one had a very small gap between the blades and the outer wall. The batteries were getting torn and shredded into little pieces to the point that i had to have a magnetic belt to remove the fine pieces of shredded metal. You don't want to crush or shred the batteries, you just want to crack them. It was causing me a whole lot more work than i needed. Their are some instances where you want that affect, but this is not one of them. All we are really trying to do is get to the powder inside with the least amount of chemicals, work, or trouble involved. Sort of like cooking an egg! We want the yoke inside, but the shell is worthless to us. We only want the hammer mill blades to crack the batteries open so we can get access to the silver inside. Think of hitting an egg with a baseball bat! For this application i guess the clearance between the blades and the wall could be any distance that you want as long as it doesn't shred it into fine pieces and the machine still performs as required.
