Abstract: A method and apparatus for grinding iron ore or iron ore concentrate is able to grind iron ore or iron ore concentrate economically. In the method and apparatus disclosed, the material is ground in circulation in a material bed roll mill, one fraction of the iron ore or iron ore concentrate ground in the material bed roll mill is recirculated to the material bed roll mill and the other fraction of the iron ore or iron ore concentrate is classified into oversize material and fines, and the oversize material is returned to the material bed roll mill.

Abstract: The invention relates to an apparatus for classifying charge material, comprising a static classifier which has a ventilating base oriented obliquely to the vertical and traversed by classifying gas; an inlet opening for charging the charge material to the ventilating base; an outlet opening for the coarse material; a downstream dynamic classifier which comprises at least one rotor; and at least one outlet opening for the classifying gas laden with fine material. The ventilating base has a ratio of width to vertical height of at least 0.45, preferably of at least 0.6.

CPC classification number: B02C4/305
Abstract: The invention relates to a grinding roll with a basic roll body as well as a plurality of wear protection elements made from hard metal which form at least a part of the roll surface. The basic roll body has recesses extending in the circumferential direction, a plurality of wear protection elements being disposed one behind the other in the circumferential direction in each recess.
Abstract translation: 本发明涉及一种具有基本辊体的研磨辊以及形成至少一部分辊表面的由硬金属制成的多个磨损保护元件。 基本的辊体具有沿圆周方向延伸的凹部，多个耐磨保护元件在每个凹部中在圆周方向上一个接一个地设置。
