Casting the ball in epoxy was quite the journey. The plan was to do it in two steps. First, pour just enough to hold the torus in place. Then, pour the rest of the ball. The epoxy process was similar to the OOMOO (mix and combine in a specific ratio), but with the added step of using a vacuum pump to pull out air bubbles before pouring.

In addition to steel balls, the wet ball mill also needs to add liquid to participate in grinding. Usually, the proportion is steel ball: material: water=4:2:1. The nature of different materials is different, so the actual steel ball, material, and water proportion will be adjusted, and determined by the experimental test. 4) Different application

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.
