MATERIAL SELECTION FOR MECHANICAL SEALS

Mechanical carbons aremanufactured by blending together types of amorphous carbon (i.e., lampblack, charcoal, or coke) and carbon graphite with a carbonaceous binder (i.e., pitch or resins). The source of the raw materials not only helps determine the physical properties of the carbon but also the type and amount of impurities.

The Sizing & Selection of Hydrocyclones

CYCLONE DESCRIPTION AND BASIC OPERATION Figure 1 shows a cutaway view of a typical cyclone. During operation, the feed slurry enters the cyclone under pressure through the feed pipe into the top of the cylindrical feed chamber. This tangential entrance is accomplished by two types of design, as shown in Figure 2. Since the
