Modifiion In Ball Mill Portland Cement

Resulting – cement slurry – flows into storage tanks When limestone is used it has to be blasted then crushed usually in two progressively smaller crushers (initial and secondary crushers) and then fed into a ball mill with the clay dispersed in water The resultant slurry is pumped into storage tanks.
