Product Advantages. Increased mill output at same fineness; Increased fineness for same energy input; Reduced grinding costsCement clinker - Wikipedia,Cement clinker is a solid material produced in the manufacture of Portland cement as an intermediary product. Clinker occurs as lumps or nodules, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage.SikaGrind®-108 KH,SikaGrind®-108 KH is a liquid cement grinding aid with performance enhancing properties.

Product Advantages. Increased mill output at same fineness; Increased fineness for same energy input; Reduced grinding costsSikaGrind® for vertical roller mills,The grinding of the finished cement consumes approximately one third of the total electrical energy of a cement plant. Vertical Roller Mills (VRM) have a clearly higher energy efficiency than ball mills, even if the ball mill is combined with a roller press. This and further arguments led to the increased share of VRM for the grinding of finished cement.
