kiln. Depending on the process type, kilns have length-to-diameter ratios in the range of 15:1 to 40:1. While some wet process kilns may be as long as 210 m (700 ft), many wet process kilns and all dry process kilns are shorter. Wet process and long dry process pyroprocessing systems consist solely of the simple rotary kiln.Web

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 …Web
