Journal of Physics: Conference Series PAPER OPEN

As discussed in the literature [1,2,4], there was significant effect of using grinding aid in cement grinding. Grinding aids are active surface agents that counteract the agglomeration of very fine particles on the grinding media, thus inhibiting the grinding effect and therefore reducing production rates. A number of grinding aids ar e ...
