Increased Line Mineral Addition in Cement the affect . - UniSAjulie.millsunisa.edu. Tom Benn. ABSTRACT: The greenhouse gas emissions produced during the manufacture of cement clinker can indirectly be reduced by incorporating mineral additions in the cement. Blending cement kiln dust with line mineral addition will reduce the amount of kiln dust being sent to land fill.addition line to cement mill,Role of lime stone in cement? - Page 1 of 2 - International Cement .Therefore, to see if it works in your situation, you would have to do plant trials by incrementally increasing the line content and decreasing the gypsum .
