WhatsAppعرض المزيدPolishing Process The process begins with the use of coarse diamond segments bonded in a metallic matrix. These segments are coarse enough to remove minor pits, blemishes, stains, or light coatings from the floor in preparation for final smoothing. Depending on the condition of the concrete, this initial rough grinding is generally a three to fourstep process.

In the next state of the process, clinker is cooled in coolers. The hot air from the coolers is returned to the preheater in order to save fuel in the overall process. The clinker is then ground to produce portland cement. Gypsum is added during the grinding process to control the set rate of the cement.

These have been used for many years for the less exacting rawmilling process, but recently roller mills, in combination with highefficiency separators, have been used for cement grinding. The grinding action employs much greater stress on the material than in a ball mill, and is therefore more efficient.

Fineness was long controlled by sieve tests, but more sophisticated methods are now largely used. The most common method, used both for control of the grinding process and for testing the finished cement, measures the surface area per unit weight of the cement by a determination of the rate of passage of air through a bed of the cement.
