High trapped fields in bulk MgB2 prepared by .

05.11.· Flux pinning in bulk MgB 2 seems to be dominated by grain boundary pinning. Therefore, nanocrystalline MgB 2 has better pinning properties than the standard bulk material with grain sizes in the micrometre range. Nanocrystalline MgB 2 with high critical current densities exceeding 10 5 A cm −2 at 20 K in fields of 1 T can be produced by highenergy ballmilling [].

Ball millWikipedia

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.

Chapter 18. Feed Milling Processes

Cereal grains can be expanded to a very low bulk density, whereas protein concentrates low in starch may remain unaltered in bulk density. Raw starch is a requirement of a good floating pellet; 90 percent being gelatinized during the 30 to 60 seconds the feed is in the expander cylinder. Pressure builds up to several atmospheres due to forward passage of the material into a smaller volume
