Rotary Kiln – IspatGuru

Rotary kiln process . The rotary kiln carries out several functions simultaneously. It is a device for conveying, mixing, heat transfer, and reaction. These functions are needed to be in harmony. The charge in the kiln moves both radially and axially.

THE ROTARY KILN Cement is created by heating crushed limestone with clay, slate, blast furnace slag and other materials, then cooling and grinding the resultant clinker to create a fine powder. Most modern cement plants use a dry process which is more thermally-efficient than the older wet process.

11.6 Portland Cement Manufacturing

In the wet process and long dry process, all of the pyroprocessing activity occurs in the rotary kiln. Depending on the process type, kilns have length-to-diameter ratios in the range of 15:1 to 40:1. While some wet process kilns may be as long as 210 m (700 ft), many wet process kilns and all dry process kilns are shorter.

Temperature Measurements in Cement Manufacture

There are more than 2,000 active cement plants around the world producing over 3.5 billion tonnes per year. They produce cement by heating crushed limestone and other ingredients in a rotary kiln to produce clinker, which is milled to a fine powder to produce the finished product.

Rotary kilns for cement plants

modern cement plant. The 2-base rotary kiln is a statically determined beam system, where the support load is always known. It is a shorter and wider kiln, with a reduced slope to maintain the material retention time, similar to a 3-base kiln. The larger diameter reduces the gas velocity and the dust recircula- tion, and secures a lower burning zone thermal load (Gcal/h/m2) at the same

Manufacture of Portland Cement- Materials and Process

The burning process is carried out in the rotary kiln while the raw materials are rotated at 1-2rpm at its longitudinal axis. The rotary kiln is made up of steel tubes having the diameter of 2.5-3.0 meter and the length differs from 90-120meter. The inner side of the kiln is lined with refractory bricks.

Manufacturing of Portland Cement - Process and Materials

The rotation of the rotary kiln causes the flakes to move from the upper end towards the lower end of the kiln subjecting itself to higher and higher temperatures. The kiln is fired from the lower end. Normally for the manufacturing of cement, the fuel used are powdered coal, oil or natural gas.

Cement Kilns: Early rotary kilns

With the arrival of rotary kilns, cement manufacturing processes became sharply defined as wet process or dry process. In the Wet Process, the kiln system is fed with a rawmix in the form of a liquid slurry, typically containing 30-50% of water by mass. In the Dry Process, the kiln system is fed with a rawmix in the form of a dry powder. The process selected depends to a certain extent upon
