Beryllium metal, in solid form and as contained in finished products, presents no special health risks. However, like many industrial materials, beryllium does present a health risk if handled improperly. The inhalation of beryllium dust, mist or fume can cause a serious lung condition in some individuals.
One method would be to monitor the noise levels within the grinding mill using Acoustic technology such as Metso SmartEar TM OCS which measures steel on steel impacts within the mill. By measuring the noise levels within the mill, you can adjust the mill speed to compensate and bring things back in line, resulting in more efficient grinding and ...
Beryllium azide, BeN 6 is known and beryllium phosphide, Be 3 P 2 has a similar structure to Be 3 N 2. A number of beryllium borides are known, such as Be 5 B, Be 4 B, Be 2 B, BeB 2, BeB 6 and BeB 12. Beryllium carbide, Be 2 C, is a refractory brick-red compound that reacts with water to give methane. No beryllium silicide has been identified.
Bertrandite 1 beryllium is the principal mineral mined for beryllium in the U.S. while beryl 4 beryllium is the principal mineral mined for beryllium in the rest of the world. Beryllium is used industrially in three forms as a pure metal, as beryllium oxide, and most commonly, as an alloy with copper, aluminum, magnesium, or nickel.
May 23, 2012 Beryllium oxide BeO is a more serious hazard than pure Be but it is now in pretty rare use. Machining of BeO is by grinding and that is done in a glove box. Some Brush Wellman shops used to use only a vacuum close to the cutting tool to suck up chips when machining pure Be.
