Energy Consumption in Metal Additive Manufacturing ...

Primary material production (179 kWh /kg for titanium and 19 kWh /kg for tool steel) consumes more energy than most of the above processes do. Therefore, the energy consumption represented by material waste is critical. The material waste in machining is represented by the buy-to-fly ratio.

Ore processing – Waihi Gold

Ore is stockpiled (1) at the processing plant, and the process begins by feeding the ore into a hopper with a loader. The ore is conveyed, and lime is added (2) to raise the pH of the ore. Following crushing through a jaw crusher (3), the ore is fed into the semi autogenous grinding (SAG) mill (4) along with water and steel balls.

Mill (grinding) - Wikipedia

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
