The video is just a demo, however I take your point. Next time Ill demo with a full hooper. I was crushing quartz mixed with iron stone... Cheers Rick
 
Hi RR very nice build.

A couple of questions if I may

What material was the shaft fabricated from and what size punch plate did you use for the outlet?

Cheers

Jim
 
The shaft is 4140 stainless, 25mm. The machine does not use a punch plate, material that is over size is classified using a hydro-cyclone setup. Over size is milled again. This helps prevent over grinding. Cheers Rick
