Fantastic job. Your Pa would have been so proud of you, having been a sheet metal worker/ blacksmith himself. Goes to show a vision with real determination always pays off !!!
Well done mate, good to see a build that most of us are able to complete without fancy hi tech tools. Ya got to be happy with that. I hope it gives you many hours of use and thanks for sharing.
That was the aim Scott, just to show that anyone can make one reasonably cheap with basic tools. I'm absolutely stoked at how well this one works. Will be interesting to see if I run into any problems with it over time. As it stands now, It seems to be super strong and reliable. Perfect for the small scale guys like us. Thanks for tuning in once again mate. 🍻🍻🍻
I just saw that BlackLabel! Thank you so much. You will be happy to know I intend to run competitions on my Patreon soon to show my appreciation to everyone that's helping me on my journey to becoming "The Goldman". I'm hoping to do roughly 1 gram of gold per month in random draws. Could be a nugget, fine gold in a vial, buttons from hard rock mining etc. Will also be doing random draws for paydirts rock samples! Thanks once again Oliver. 😁
Dude I watched this in its entirety a long time ago but i forgot or was loopy. Your execution and design were spot on, and you really did a good job! I've mocked up an 8" pipe with 1/4 steel plate backing, and just gonna swing shackles and chain. Running off corded right angle grinder. But I'm fricken lazy
Thanks heaps Aug! I'd really like to see a vid of your mentioned crusher in action by the way mate. I get all my ideas, by seeing everyone elses ideas come to life. So it's always great to check out another build 👍🏿👍🏿👍🏿
Yeah man same principle of sideways hamburger. Outer plate just all thread bolted and sandwich the pipe. Need a fill tube, maybe 2" steel pipe. I lack a welder. Have a little experience, training, but being a carpenter a welder is low priority. But now I need one damn it! ✌️✌️⛏️⛏️ right on bro! It's definitely a lifestyle
Thanks heaps John! Good luck with your build. If your build is roughly the same size as mine, go a 30mm throw on your eccentric shaft instead of a 20mm throw like mine and aim for 250-300rpm and she will be a bloody ripper! Cheers 🍻
Thank you Toby. Couldn't believe how well it turned out! 900kg/hr is bloody fantastic and will make my whole process sooooo much easier. Thanks for tuning in also 😁
Haha thanks JM! A lot of my equipment has been kindly given to me or sold to me cheap by old fellas of the game. One day, when I'm worn out and ready to slow down I hope to pass all this gear on to some other young fella with passion and drive for gold mining also.
Areet man. Loving the build 👍 I've always wanted to make one too since seeing the price of just a tiny one and this is really high quality. Just a thought about keeping the batteries cool. You could make a thing that holds Ice inside like a flask that wraps around the batteries. Never thought about it being a big problem before in hot places but I see now. Or make a mini freezer to wrap around. Where there's a will there's a way! 👍❤️💛💚
Thank you my Rasta brother! I had been waiting patiently for years for the right sized jaw to come up for sale at the right price and it just never happened. So bugger it, let's make our own and make it as basic and strong as possible so hopefully other can do the same. I think it would be sensible to just use the little milwaukee for smaller jobs in future, batteries don't like copping the beating that I gave to them over those few days 🤣. It's OK though. Still in warranty 😉
Bryan You are one A grade bush engineer making do with an angle grinder and drill and a stick welder. great job on the build. I look forward to seeing the whole show in action and some of that gippsland yella.
Thanks Jethro! Hopefully by the time you get down here she will be a fully automatic show. Just got back out of the bush last night. Will get back to your message shortly 😁
Looks great man. I would add some rebar to the plates on each side but offset them. That way as time goes, you're just wearing the rebar down, plus they'll have more grab for grinding the rock down.
Thanks Andrew! I started with the flat plate because some of the other flat plate jaws I've used seem to get a smaller and faster crush than the typical corrugated jaw designs. I think rebar would be essential if my ore was really hard though, I can always add it later if need be, but so far it works amazing as is and I expect the Bis400 wear plates to last a very very long time. We will just have to wait and see exactly how long they last though.
nice build sonny Jim .....just a little more throw and you are good to go .... seen a lot of people try to build their own and this one was pretty good. .... now lets see what is in all the beautiful ore
Thanks Jeeffffffffff. I would certainly go a 30mm throw if I build another one in future roughly this size. But I was amazed how well it worked as is. Especially happy that I didn't have to add anything to the jaw faces. Having 2 flat surfaces means I can close it right up if need be. Yeeeehhhawwwww buddy!
Thanks Shan! I'm still brainstorming about how to approach to setup as a whole. But yes, the general idea will be to either let gravity do the work or have a conveyor lift the ore from ground level up into a hopper above the impact mill that will incorporate a vibratory feeder so I can perfectly set the pace of the whole plant. I'm hoping to simply feed the jaw crusher 250kg at a time to fill the feed hopper. Then let the rest happen automatically so I can walk away and do other things while it runs 😁
Very nice! I like the dedication of working into the late night. Who made the eccentric for you? That is probably the most limiting factor of this type of build!
Thanks mate! Theres not enough hours of daylight to spend on all my little projects, so I've got an excellent headlamp 😁. Friends of mine who own BluArc Enginnering here in eastern Vic turned up the Eccentric for me on the lathe, I just drew them up a dodgy drawing of what I needed and they knocked it up for me very easily. Need to get myself a lathe. The possibilities are limitless then.
@@mikemullenix6956 Yes the eccentric shaft was the one bit I couldn't do myself. But any engineering place will be able to make one up for you pretty cheap. 👌
Haha he's real champion old Morgan. Mind you, nearly 9 years of hunting and mining have taken its toll on his hearing. So he would likely sleep through an earthquake 🤣
That would have been good to know before I spent 34 5 inch cut off wheels 🤣. Nah it's OK. I enjoy to meticulous labour. I'll remember that for next time though 😉.
incredible build scripped to the end to lazy to see how it was built until seeing the final results. Going to have to watch hole video now that is very impressive. just subscribed what do u use for finishing the mill? or are you still building? you building a shaker table? I'd have to watch that video to lol. I have a past producer lode mine here in the states Lovelock Nevada got lucky with a auction 5 Miles from my house 4-6 foot ball mill excellent condition I was the only person new what it was so I picked it up just a tad under what it's worth in scrap metal. There is a old jaw crusher that was used in 1940 on the mine still anyone know the chances of it working again? any thoughts is appreciated.
I've seen older crushers come back to life! So 1940s would certainly be repairable brother. After feeding the ore into the jaw crusher, it then goes through my impact mill and then ball mill before being gravity separated. Have recently acquired a shaker table to add to the plant, just haven't gotten around to fixing it up and installing it yet. Hopefully soon! My recovery will be much much better with the shaker as opposed to a sluice
Mr Karl really you have grate experience about making jaw crushers smartly. I want to prepare one like this for gold minning project in Hargeisa so may you help me for further more indications about that?
It wasn't too hard, just very slow given the basic tools. So the reduction box is 6:1, the driver pulley is 63mm and the driven is a 112mm. So roughly 250rpm at the eccentric. Cheers mate!
Bloody sensational vid! Been waiting on something like this for years to help with the primary crusher build. So witht the cam you would run with 15 mm instead of 10 mm? You based in vic what was the name of the company id like to follow this build to the tee. Cheers brother.
Thanks heaps Timeis Now! Yes if I were to do it again I would go for a 15mm difference in the eccentric. The 10mm I did works amazing for my setup, but that little bit of extra throw would work even better! I am based in Vic yes, which company are you referring to though sorry?
Hey, you made a great job of the jaw crusher, hope you don't mind I'm gonna copy everything you did😁 might make the opening 200mm at the top for a bit bigger rock. Just wondering what hp your engine is and did you buy a separate reduction box and bolt it on or did the engine have it on already? Cheers from Donegal in Ireland🍻
Sounds great mate! Best of luck with your build. I've made some more mods to the Jaw crusher now, including 2x old brake rotors welded together with a 30mm taper lock pully and bush welded in the middle. That turned an already very capable crusher into an incredibly capable crusher. Nothing can stop it now! The old Honda G300 is 7hp and had the reduction box fitted to it from factory. They still have the option of fitted reduction boxes when purchasing new today. 👍🏼👍🏼
Ill add one eventually Steven, I'm just still deciding what I have laying around that would work best. I think the main thing I would want out of a flywheel is to balance the whole unit a bit better and remove a little bit of the vibration though. I just don't want too much excess energy to back feed the reduction box when I turn it off. 🤔
Great job, looking to do something similar. I'll be using a couple of engine flywheels for kinetic energy and powering it with me ol lister Cs diesel engine.
Specifications aren't all that relevant in this case seen as I used scrap steel to build it. Anybody can build one with similar steel they find with different dimensions to suit their needs 😁.
Bearings have held up no problems at all Richard. I've put quite a few tonnes through the little Jaw crusher now and it's been bloody fantastic. Well and truly exceeded my expectations. I have made some minor changes to things also though. I will upload a review video of the Jaw soon, detailing changes and better ideas for others to try. Thats a good idea mate, even just a little welded plate behind the bearings each side would be very handy. That would remove the slop from the bolt holes. I have the bearings pushed all the way back towards the motor for this reason, but little positioning plates behind the bearings would be much better. 👍🏿👍🏿
Good job sir, I like your own idea, will you teach me how to make it, I want to build one for my self, I'm an iron and metal welder, thanks, and God bless you
Good job, I’m building one that’s modeled on yours. So did the angel of the jaw work well and if so what was the degree ? Also were yer bearings roller or ball and what size were they ? I really like this simple design ! I’m gonna copy this
Thanks Joe! The angles all worked great, top of the jaw was approx 100mm opening, the bottom was set to about 20mm gap. Ball bearings for the bearings, 40mm on the centre of the eccentric, 30mm on either side.
So is Oxy acetaline hard to get there ? A "Victor Wrench" (cutting torch) would save you a lot $$$ on cut off wheels . An if it is a chain saw concrete type "Cut Off" with good 16"/18" wheels . You may need to make the guard...
This is awesome, I have all this steel around to build one but having trouble finding eccentric shafts and bearings to match. Any pointer where I can get some?
The eccentric is really something that will need to be manufactured by your local engineering/fabrication shop Beefer. Or if you have any friends that own a metal lathe, go visit them and draw up some designs. Bearings are about the easiest bit usually, readily available online. But if you get stuck, ask the fabrication shop to source them for you when they do the Eccentric 😁
I went with a 10mm difference, which more or less gives me a 20mm throw. 30mm diameter either side of the 40mm centre. I would go with a 15mm difference if I did it again, giving it a 30mm throw. I wasn't confident my engine was going to deliver the power it needed at that time. But in retrospect, it would have handled it fine with the pulley ratios I'm currently using.
500mm over-all length. The eccentric centre part is 40mm diameter and 180mm long from the centre of the work. Each 30mm diameter side of the shaft makes up the other 320mm. Hope that's helps
Very cool mate, I hope you upload a video of the finished product for me to see! I'm currently thinking of making a mini jaw crusher and impact mill for portability.
Ill have to try that one day mate. My single phase genny is great for welding up to 10mm roughly. The 3 phase genny up at the plant can't produce the same power on one leg though unfortunately.
The desired throw depends on the power you've got to drive the machine. For my small engine and reduction box, the 10mm is fine. I don't think I could go to 15mm without it bogging down too much. 12.5mm would be perfect. The pulleys were originally 63mm and 112mm. But I changed that later on, made both bigger, but the same ratio. Simply to give the belt more surface area to grip on. The 63mm didn't have the surface area I needed. Your machine may be different of course, depending on engine speed and the reduction box ratio. My reduction box is 6:1. The ideal speed at the eccentric is approx 250rpm, so just aim for that, and you will be all sweet mate.
@@TheGoldmansChannel while doing research I found motors without 15HP reduction. There are 2:1 reducers, no other models. Without reduction the size of the driven pulley would be enormous.
The current Honda model code for the 6:1 reduction box is HX. Have a google for GX270-HX8 and see what that comes up with mate. Without the reduction box there are 2 options, a very large driven pulley, or a secondary Shaft mounted between more bearings. That way you can have a small driver on the motor, to a larger driven on the second shaft, which then has a smaller driver pulley next to it, which then in turn goes to a larger driven pulley on the Jaw crusher itself. Essentially making yourself a reduction box, with just 2x extra pulleys, an extra shaft and extra bearings. The reduction shaft should be kept as short as possible if only using a bearing on each end of it, or if it needs to be longer, add a 3rd bearing between the 2 pulleys in the middle somewhere. Not a complicated job, just requires some extra bits and pieces. 😊
I drew up my shaft design and gave it to my buddy who has an engineering shop. He turned it up on the lathe. I assume he started with the centre diameter and then offset the jaws to throw an eccentric movement and cut down each side to specs from there. I've got a video of it on the lathe if you want me to email it to you? Cheers!
If I want it finer I can just adjust the 2 bolts in a bit further to close up the bottom of the jaw. At this stage though, the output size suits my setup just fine. The impact mill can take 40mm chunks of rock and the rock coming out of the jaw is less that 20mm. Perfect 😁
No plan mate. Seen as it was mostly made out of recycled steel I just designed it based on the width of the C channel steel. Unless people purchased the same steel off the shelf my measurements would be useless to them. Scrap is best 😁
Thank you Tyler, I'm super happy with how the build turned out. Ive only made a few little changes to it since the build. (Switched to B section pulleys and belts, slightly larger in the driver pulley, slightly smaller in the driven pulley). Just to give it more surface area on the driven pulley to get belt grip. Something to keep in mind if you build your own. The channel was 180x75mm.
I just drew it up on paper and got one of my engineering friends with a Lathe to turn it up for me. 500mm long. Centre offset diameter is 40mm and 180mm wide. Each centred side is 30mm in diameter.
Good morning sir, from nigeria, first I'm so happy to see that you replied to my post, please sir, can you write down for me the materials needed for this job, don't be angry with me sir , size plates and bars and others
I used 4 pillow block bearing housings with sealed ball bearings for this project. The exact ones you will need will depend on the size of your shafts. Best to contact a local industrial supplier for common sizes and such for your own project. Cheers!
Seen as you asked nicely, the 30mm pillow blocks are P206, the 40mm pillow blocks are P208. The bearing codes for them I can't quite see though sorry. But that should be enough for you anyway. Cheers!
I noticed that you didn't bother to bevel any of the edges of those pieces to get maximum weld penetration. That might come back to haunt you, depending on how hard and frequent you use it. On the other hand, it looks to work quite well. That is absolutely a win on your project design. 🤔✌️😎
May just have been tricky to see in the video, but I ground out almost every edge and join that required welding. Got great penetration on them. Mind you, welding isn't one of my best skills, I'm still very new to it! So far so good on the structural integrity of the jaw crusher. I use it heaps and have given it a really hard time and it so far hasn't given me any trouble at all. It just keeps munching! 😁
I guess i missed it then, but all good because the only person you need to please, is yourself. And again, it appeared to be working exactly the way you designed it to. I'm a prospector/miner myself and have a couple claims over here in the US. I was watching your video to educate myself with the equipment. ✌️😎
@aumetalmental8403 Fortunate that I only need to please myself with my engineering skills. I don't believe they're quite up to scratch to make or sell for others. Something would go flying and I'd end up with a law suit 🤣. Cheers mate, I hope your projects over there in the US pan out really well for you
Howdy John, the eccentric shaft I had turned up on a lathe was 500mm long X 30mm diameter either side of the 40mm diameter X 180mm long eccentric. Cheers!
Sounds good John, give yourself a little bit more throw on that Eccentric shaft too if you can. If you've got 60mm bar cut the sides down to 45mm diameter. The 20mm throw on mine is good, but it could use 25-30mm throw. That would have made it much better 👍🏿
@@jansynowiec Because it will work a little better with more throw on the jaw. Mine moves 20mm when rotating. But 25-30mm movement would have worked better. :)
Hey Bradley. I'd be happy to look over your plans if you email them over to me at thegoldmanschannel@gmail.com I'm no expert, but I may be able to identify some issues or areas for improvement?
No I don't need any help these are original speck drawings.just sold my other one which I didn't think I needed but now I do, this was to see if you wanted them maybe make your own?
Love the videos keep it up. But you my friend have given me some good ideas. Dodgey designs make it better because you built it. So you know how to fix it properly. I like the idea in this video.
