Build a simple rock crusher
Jan 13, 2016· just start collecting some scrap steel and build your self a small jaw crusher... the concept and build is very easy heres one i built to crush rock to 1/8" to free the placer nuggets trapped in the solid rock. any other type of crusher was destroying the nuggets. she is not pretty to look at but she worked great! 4" x 6" with a 1/4" stroke
