Ball Mill Introduction . There are three main stages to mineral processing in the mining industry.These are: Comminution (crushing and grinding).; Beneficiation (separation and concentration).; Smelting and refining.; Ball mills are employed in the comminution stage as grinding machines (size reduction).The purpose of grinders in the mining industry is …
Sublimation for Beginners: Equipment, Tools, and Supplies
Sublimation Blanks What is Sublimation? Sublimation is also called dye-sublimation (or dye-sub) . It's basically a technique where you use heat to transfer dye to your material. The biggest difference between sublimation and heat transfer vinyl is that the dye becomes a part of the material when you sublimate.
