Manufacturing - the cement kiln. Most Portland cement is made in a rotary kiln. Basically, this is a long cylinder rotating about its axis once every minute or two. The axis is inclined at a slight angle, the end with the burner being lower. The rotation causes the raw meal to gradually pass along from where it enters at the cool end, to the

Portland cement clinker is nodules (diameters, 5–25 mm) of sintered material produced by heating a homogeneous mixture of raw materials in a kiln to a sintering temperature of approximately 1450 C for modern cements.The resulting clinker consists of four main minerals: 11 1. Alite or tricalcium silicate, Ca 3 SiO 5 (in oxide terms 3CaO.SiO 2), abbreviated to C 3 S;

The manufacturing process of Ordinary Portland cement is made primarily from calcareous and argillaceous materials, such as limestone or chalk, and from aluminium oxide, silica oxide, ferric oxide and magnesium oxide found as clay or shale. ... The raw mixture prepared is heated in large rotary kiln up to about 1400-1450 C. A series of

Apr 30, 2016 Portland cement is manufactured in a rotary kiln. The rotation of the kiln causes the raw material to gradually pass along and undergo chemical reaction from where it enters the cooler. The molten clinker gets cooled from -1300- C to 100- C in the cooler over a period of time

If you find any problem in the operation, solve it immediately. In general, the maintenance of rotary kiln is a complex process, here are some tips will be helpful

ADVERTISEMENTS: Portland cement can be manufactured by intimately mixing together calcareous and argillaceous stones containing silica, alumina, and iron oxide etc. and burning it in large rotary kilns at a temperature of approximately 1400 C to 1500 C. At his temperature the materials partially fuse, forming clinker. This clinker is cooled and ground to fine power. Usually […]
