Wet Process for Manufacturing of Cement
21.06.2016 · The dry material undergoes a series of stone reactions in the hottest part of the kiln and some 20 to 30 percent of the material becomes liquid, and lime, silica and alumina recombine. The fused mass turns fuses into balls of diameter 3 to 25 mm known as clinker. The clinker drops into coolers where it is cooled under control condition.
How Cement Is Made - Portland Cement …
The most common way to manufacture portland cement is through a dry method. The first step is to quarry the principal raw materials, mainly limestone, clay, and other materials. After quarrying the rock is crushed. This involves several stages.
11.6 Portland Cement Manufacturing
Five different processes are used in the portland cement industry to accomplish the pyroprocessing step: the wet process, the dry process (long dry process), the semidry process, the dry process with a preheater, and the dry process with a preheater/precalciner. Each of these processes accomplishes the physical/chemical steps defined above.
