Hi
I finally delivered my latest milling equipment. The design was initially copied by the membets of treasurenet forum which I should thank.
The electromotor used is a 1.5 HP 3000 rpm single phase. The pulley system used increases the mill rpm more than 3000 rpm.
The main shaft used is a 20mm diameter, and 3 sets of modified chains are attached to shaft with screws so chain replacement is easy. As it can be noted, unlike the designs by treasurenet members, I used a length for chains that when it is running, only 1-1.5mm gap is left to the body of mill.
Output holes are 5mm in diameter. This pulverizes rocks into 93% passing mesh 100, and for circuit boards 90% passing mesh 100.
It literally instantly pulverizes rocks or circuit boards into fine powder. Here is an example when I dropped a closed feast size hematite ore into the mill.
I will be using this mill to pulverize left over depopulated circuit boards, then run them on homemade shaker table to recover copper.
Best regards
