01/09/2007 Besides ball mill, different types of mills which have different grinding mechanisms such as high pressure grinding rolls (HPGR), vertical mill and Horomill are being used in cement industry. Particularly HPGR has a great acceptance in cement industry for almost 20 years because of its ability to reduce specific energy consumption up ...

Effect of Grinding Aids on the Particles Characteristics ...

Mechanical effects and proper grinding result in a compressive residual stress at the surface. This is beneficial for fatigue. Thermal effect produces the opposite effect, with a residual tensile field at the surface. ... The mechanism of quench cracking and grinding cracks is identical. The cracks are typically intergranular and follow prior ...
