A confirmed abnormal beryllium lymphocyte proliferation test without evidence of lung disease is diagnostic of BeS. BeS with evidence of a granulomatous inflammatory response in the lung is diagnostic of CBD.

Residual reduction slag containing these beryllium pebbles is purified by vacuum melting. Vacuum melting uses a magnesium oxide crucible and a graphite mold to produce an ingot weighing 180 to 200 kg (400 to 450 lb). The ingot is "skinned" (machined) to remove the high-carbon material adjacent to the mold wall.

Pebble Mill Grinding - Mineral Processing & Metallurgy

Pebble Mill Grinding. Essentially tube mills and pebble mills may be considered as ball mills, the basic difference being that the ratio of length to diameter is greater. Usually the shell length is between 2 and 5 times the diameter. These mills are primarily used to grind various materials to 100 mesh and finer.

Manufacture of beryllium for fusion energy applications

Beryllium pebbles are processed by vacuum melting to eliminate impurities 15, 16. Molten beryllium is poured into a graphite mold under vacuum and solidified. The graphite mold reacts with the molten beryllium to form a beryllium carbide skin on the outer surface of the ingot. This carbon rich skin is removed using a lathe.
