Little abrasion wear, Long service life

Based on 30 years of development experience of grinding equipment, LM Heavy Industry produced LUM Series Superfine Vertical Roller Grinding Mill to make ultra-fine powder. The grinding roller doesn't contact with millstone usually, which makes abrasion little and service life longer.

Applications: Superfine dry powder of none-metal ores such as calcite, marble, limestone, coarse whiting, talc, barite and dolomite and so on.

Pyroxene structure and structure

Pyroxene Crystal structure Britannica

The essential feature of all pyroxene structures is the linkage of the silicon-oxygen (SiO 4) tetrahedrons by sharing two of the four corners to form continuous chains. The chains, which extend indefinitely parallel to the ccrystallographic axis, have the composition of (SiO 3) n (Figure 1).

University of Minnesota’s Mineral Pages: Pyroxene

Pyroxene minerals share a similar crystal structure and their physical properties are so similar they are often only identified as ‘pyroxene’ in the field. Typically dark green to black in color, some pyroxene varieties range to light green or white. All of them are harder than glass, and exhibit two well-developed cleavage directions.

Pyroxene mineral Britannica

The range of possible chemical substitutions in pyroxene is constrained by the sizes of the available sites in the structure and the charge of the substituting cations. The Xcation sites in general are larger than the Ycation sites. Extensive atomic substitution occurs between the ideal end-member compositions.
