7 SAMPLING AND PREPARATION FOR LABORATORY MEASUREMENTS Introduction There are three methods for collecting radiation data while performing a survey. A direct measurement is obtained by placing the detector near or against the surface or in the media being surveyed and reading the radioactivity level directly. Scanning is an evaluation technique
In mass finishing systems, regardless of the part shape, the grinding or polishing media totally surround (envelop) the parts to be finished, reaching all surface areas. Naturally, this also applies to drag finishing. Especially in the medical implant industry, drag finishing systems have displaced robotic grinding .
The second possible production method of grinding media is the fused process. All necessary raw materials are smelted and homogenized in a kiln at high temperatures of more than 2000°C. The hot material smelt leaves the kiln and the bead forming process from the smelt takes place—droplets are
samples include grinding, shearing, beating, and shocking. At times it is difficult to discern between the different forces that are used, but for the sake of simplicity we will segregate the different tools into these categories. In practice, scientists mix and match disruption methods to meet their needs. Though an ideal disruption method
