Effect of the mechanical activation on size reduction of crystalline .Dec 29, 2009 . The actual process of mechanical alloying starts with mixing the component powders in the correct proportion and loading the mixture into the grinding mill along with the grinding medium – generally steel balls. The mixture is then milled for the desired length of time until a steady state is reached, ie when.mixing grinding activation,Regarding addition of dry Fly Ash in Cement grinding process .In my experience, dry flyash is normally added to the cement as it enters the cooler (to ensure adequate mixing). This is the cheapest option, however co-grinding of the flyash in the cement mill is becoming increasingly popular due to the mechanical 'activation' of the flyash, which allows for a higher.
