A material's heat transfer properties refer to how heat can move from one source to another. A material can be categorized as either a conductor, meaning it transfers heat very well, or an insulator, meaning it holds on to heat well (and subsequently is resistant to transferring it to other materials). Metals (especially non-ferrous metals ...

Figure 11.30-1 is a flow diagram of crude ore processing. The first processing step is to reduce the diameter of the ore to approximately 1.6 centimeters (cm) (0.6 inch [in.]) in a primary jaw crusher. The crude ore is then passed through a rotary dryer, which reduces the moisture content from between 4 and 10 percent to less than 1 percent.
