Looking For Hand Powered Rock Crusher Info
Miner Problems replied to John Ruckman's topic in General Mining Questions
I have helped out on a hand crank crusher built out of a old strait 4 jeep motor. we will try to find a picture. we replaced the head with 1 inch steel, cut holes into the block for feed and fines removal and replaced the piston/rod with a weight on a short cable. it needed some fine tuning but it did its job.
