احصل على السعرPortland cement is obtained by grinding clinker with only minor amounts of a few other minerals, so its composition does not depart far from that of clinker. Other cements ( non Portland cements, for example pozzolanic cements, blast furnace slag cements, limestone cements and masonry cements) contain larger amounts of other minerals and have a much wider composition range.

احصل على السعرPowdered raw mix enters the kiln at one end and the burner is situated at the opposite end. The rotary kiln rotates at the speed of 1 to 3 revolution per minute (RPM). The raw mix in the kiln melts first into liquid form and then transforms into nodules due to the effect of the rotation of the kiln.
احصل على السعرTechnically, a cement producer can have almost complete control over clinker composition by blending raw materials of different compositions to produce the desired result. In practice, however, clinker composition is largely determined by the compositions of the locally available raw materials which make up the bulk of the raw meal.
احصل على السعرRaw meal is fed into one end of the kiln, either directly or via a preheater system, and pulverized coal is burnt at the other end. The raw meal slowly cascades down the inclined kiln towards the heat and reaches a temperature of about 1 450 °C in the burning zone where a process called clinkering occurs.
