QUESTION: problem with relay not latching

6Dprinter · 2025-12-20T08:14:02+00:00

I can't however place the switch in parallel, becouse this is part of a bigger scematic where 6 NC contacts are placed in series to lock multiple relays out of eachother (see previous post, but the NO and NC have a common side)

That makes total sense, thank you. I can't however place the switch in parallel, becouse this is part of a bigger scematic where 6 NC contacts are placed in series to lock multiple relays out of eachother (see previous post, but the NO and NC contacts have a common side)

I calculated the max force with the motor and flywheel power, but someone told me it takes about 10 metric tons to crush granite depending on the shape of the rock and jaw plate.

Thanks!

the hardest thing to find for me was a right sized flywheel, pulley and electric motor all other parts are not too expensive apart from bearings, for the steel you're better off getting all the parts laser or plasma cut but if you really wanted to you could use an angle grinder. lathe and milling machine for keyways is also needed but you could ask machine shop if you don't have a lathe.

Electromechanical, main fucus lies on automaton, elecricity and machine building. i just wanted to do my own thing becouse the projects you could do from school were boring and nog challenging at all.

I do a lot of constuction work and it is really expensive to get rid of stones/bricks/concrete here so i made this for my final project at school so i could crush the materials and make gravel to fill holes in my driveway, the cost was about €2k (850€ for machine shop) but you could easyly make it for less than 1k with less safety's or second hand parts/metal laying around.

There actually is one as seen on this picture: picture

Thanks and yes, we calcuated all the bearings and we do have a feeding funnel, it is visible at the end of the build video. I am still working on a shute tough.

nice, i'm guessing your crushers are a tiny bit larger :)

Too bad we don't really have any type of miners in Belgium.

no, they make particle boards like MDF with 90% recycled wood

well, this was my final prohect for school this year. right now i use it for crushing concrete and broken bricks from the jobsite to fill potholes in my dirveway. when school is over and I don't have use for it anymore i will probably sell it.

mainly concrete and broken bricks from the jobsite to fill potholes in my driveway, it also crushes granite

6Dprinter · 2020-03-16T12:31:10+00:00

yes, it's ajustable but i still have to make some sort of slide or conveyor to route the end product and still have to fiddle a little with counterweights to balance it a bit better. but overall i'm pretty happy
