    Abstract: A grinding plant comprising: a high-pressure roller press for crushing raw material into fragments; a static cascade sifter for shifting the fragments from the high-pressure roller press into fine fragments and coarse fragments, the coarse fragments being returned to the high-pressure roller press; and a separator for separating the fine fragments from the static cascade sifter into fine product fragments and less fine reject fragments, at least some of the less fine reject fragments being returned to the static cascade sifter without first pasing through the high-pressure roller press.

    Abstract: Disclosed is a magnesium alloy that has high thermal conductivity and flame retardancy and facilitates plastic working, wherein magnesium is added with 0.5 to 5 wt % of zinc and 0.6 to 3.5 wt % of tin (Sn) as a high-melting-point oxide-film-forming element, with, as necessary, 1.5 wt % or less of at least one selected from among calcium (Ca), silicon (Si), manganese (Mn) and mischmetal, the total amount of alloy elements being 2.5 to 6.3 wt %. A method of manufacturing the same is also provided, including melting high-melting-point alloy elements in the form of a master alloy in a magnesium—zinc alloy melt, followed by casting, removing a chill from the cast material, diffusion annealing, and then molding through a tempering process such as rolling, extrusion or forging. This magnesium alloy is improved in ductility by the action of alloy elements for inhibiting the formation of plate-like precipitates in a magnesium matrix structure, can be extruded even at a pressure of 1,000 kgf/cm2 or less due to the increased plasticity thereof, and can exhibit thermal conductivity of 100 W/m·K or more and flame retardancy satisfying the requirements for aircraft materials and is thus suitable for use in fields requiring fire safety, thereby realizing wide application thereof as a heat sink or a structural material for portable appliances, vehicles and aircraft components and contributing to weight reduction.
