[QUOTE="Rickrofe, post: 115761, member: 3596"] Hi As I understand it the optimal rpm for a crusher of this size is about 1400. The pullies are 1:1.22 which gives us a rotation of between 1420 - 1470 rpm; which seems to be working well. We have had the mill up and running now for about a week, it is running a .75 horse power motor at 1400 rpm. It eats through anything 6cm (a bit over 2 inches) squarish. It reduces ore down to between -100 mesh and -30 mesh. I will put up a video as soon as we are finished tweaking a few bits and pieces. probably in a week or so... Cheers Rick [/QUOTE]
