Looks pretty cool.Wonder how well it works ?

it breaks it up so small I can't see it

Well, it works good in the video in one of their adds they claim 300 tons before any wear parts need replacement. That would keep me busy for a long time. My chains are only lasting about 6 or so buckets depending on the hardness of the ore.

LOL... Sorry to hear that.

My 6 pound sledge hammer has lasted Decades And, it only has 2 moving parts.Me, and the hammer head

I've been using my single jacks for years I just keep the ibuprofen close by.

Has anyone used one of these? Or own one.

Without heavy flywheels there's a lot of strain on drive components, like chains. Also places more strain on motor bearings, etc.

The jaw crushers I can afford are made in China I don't trust those heavy flywheels.

Ya I own one and used to use it to crush before throwing the ore into the chain mill. Probably did 6 buckets before it broke. Happened right at the end of the trip so I can't remember which part exactly broke. Seemed like a hinge wore through. After such little use I'd have to agree with Jim without the heavy flywheel your relying completely on the motor to get the job done. Oftentimes the motor would bog down and I'd have to shut it off dump it out and start up again. Definitely not a dump your ore in and let it crush machine. Similar to our chain mills feed one piece at a time and hope it doesn't decide to just happily bounce in the hopper or jam up the jaws. If I could do it again I'd probably not purchase the minijaw crusher and continue with the sledge and chain mill until I could afford something more robust.

Thanks, about 6 buckets for me also K&M 11-inch mill chains worn screen cover and bolts one bolt head gone. Screen has a hole in it I repaired the mill today maybe it will make it until backup parts arrive. It works great was used lightly when I bought it second set of chains by me. Worlds Hardest Chains Rockwell #62? This quartz we have is tough

Just a thought. Maybe hardness makes for brittleness and short life(?). May be worthwhile to experiment.

Continued good luck to you and your son.

Ask yourself what hardness chain does these commercial makers of this equipment use ,and then replace your wore out chains with that type . OR use what you have and keep replacing it as it wears out . JMO

A big compromise in jaw crushers is do you want speed, or ability to crush hard ore. The only way to have both is lots of horsepower. The "throw" on the jaw determines the speed. But a large throw requires lots of power if the ore is hard. You can crush hard with less power, but with a reduced amount of "throw" on the crank.....you're taking smaller "bites".

I'm using the type of chain from the manufacture of my mill that they supply and comes with the mill new. And it still seems to wear fast. I guess as long as it pays for itself, I'll deal with it but looking for cheaper source.

I tried ordering some chains of similar construction to the rockwells that saved a few bucks but I think in the future I'd just stick with what you're doing and get them from the mill manufacture. End of the day chain is expensive no matter where you get it from and as best I could tell the one's from the mill manufacturer were the hardest chains available. I feel your chain pain!

Sure would be nice to have one of these

Hardened Security Chain​

Why is Pewag chain so hard to cut? This cut-resistance is due to both the hardness of the steel and the shape of the links.

One way steel hardness is determined is through the Rockwell rating system (also known as the HRC). This method measures how much of a dent is created in the metal when a measured amount of weight is applied. A good HRC for security chain is 56 and above.

Pewag's rating is an impressive 62 HRC for all three chains. The 9/32” and 3/8” security chains are hardened to 62 HRC 10% deep, while the 1/2” security chain is hardened to 62 HRC 6% deep. Not only does this mean they take more strength to cut, but it also means the chain is harder than most bolt cutters - they tend to have a rating of around 59-60.

Additionally, the chain links have a square profile. Hardened square link chains create a larger contact area and prevent bolt cutters from getting the necessary grip to start cutting through. K&M chains are $55 dollars plus shipping the chains are 8 inches long you get two Pewags are $16.79 a foot for 120 grade if you buy $ 200 dollars' worth shipping is free. I'm still looking I think I found some on Amazon
