A dry process kiln might be only 70m long and 6m wide but produce a similar quantity of clinker (usually measured in tonnes per day) as a wet process kiln of the same diameter but 200m in length. For the same output, a dry process kiln without a precalciner would be shorter than a wet process kiln but longer than a dry process kiln with a ...

The Wet Process and The Dry Process. From the earliest times, two different methods of rawmix preparation were used: the mineral components were either dry-ground to form a flour-like powder, or were wet-ground with added water to produce a fine slurry with the consistency of paint, and with a typical water content of 40–45%.

Rubberized mixtures can be produced by wet and dry processes. The wet process is widely used. The dry process involves adding rubber particles into the mixture directly and can consume more crumb rubber than the wet process [95]. The main differences between the wet and the dry process are shown in Table 13.3.4.
