Wet-process rotary kiln. The wet process refers that make raw materials into cement slurry contain 32%-40% water. The finished cement slurry is diffluent, so the raw materials have a good mixture, the raw material composition is uniform, so the clinker is high-quality. Dry-process rotary kiln. The dry-process rotary kiln has opposite features.
