Cement Grinding - Mineral Processing & Metallurgy

Clinker, the discharge product from the kiln, is partially cooled and broken or crushed to about ¾" - 1″ as feed to finish mills. Fineness of grind is dependent upon the type of cement to be produced. Since fineness of grind falls below standard screen size accuracy, fineness of grind is determined by use of a "Wagner'' Turbidometer.
