Sep 10, 2016  1. Introduction. Portland cement clinker is a black nodular hydraulic material. It is made by burning in a rotary kiln (pyro-processing), at least to sintering a precisely specified mixture of raw materials containing CaO, SiO 2, Al 2 O 3 and Fe 2 O 3 at temperatures of about 1400 °C. Following the clinkering process in the kiln, clinker is cooled down in coolers.
