Shell grinding allows to produce hazelnut shell powder (HSP) of different sizes and morphologies. HSPs consist of lignin (40–50% by weight), cellulose (25–28%), and hemicellulose (22–30%), but they also contain a fraction of polyphenols (flavonoids and tannins), which can be recovered by hydroalcoholic extraction [ 10, 11, 12 ].
Finely divided and free-flowing powders of a thermotropic polymer, e.g., a wholly aromatic polyester or a wholly aromatic polyesteramide, are produced by (a) extruding a melt of such thermotropic polymer through an extrusion apparatus including a downstream die member to provide at least one solid cylindrical profile thereof, during which extrusion (i) the molten thermotropic polymer is at a ...
Polymer powders produced by cryogenic dry grinding [2,4,5] are [7] available, too, however, they often show poor processabilitydue to the bad flowability of the typical irregular shaped particles obtained by comminution processes .
