Cement
Cement is one of the most vital elements for the nation’s infrastructure growth. Along with other additives like sand, water, aggregates it builds the nation. India is the second-largest producer of cement in the world. It accounts for more than 7% of the global installed capacity. UltraTech Cement Limited, a part of the Aditya Birla Group, is the largest manufacturer of cement in India and ranks among the world’s leading cement makers. Aided by suitable Government foreign policies, several foreign players such as Lafarge-Holcim, Heidelberg Cement have invested in the country in the recent past.
A significant factor which aids the growth of this sector is the ready availability of raw materials for making cement, such as limestone and coal mines which are spread throughout our country. India’s overall cement production accounted for 294.4 million tonnes (MT) in FY21 and 329 million tonnes (MT) in FY20.
The cement industries have several components which undergo extreme wear & tear along with fracture during operation. Regular maintenance & periodic repair is the key to the sustainability & efficiency of the plant. EWAC Alloys have been a pioneer in innovating the new & effective techniques for repairing these components & prolonging the life through specialised productions & solutions.

- The milled and blended raw materials from mills go to a silo and then to the kiln through the preheater.
- The preheater-kiln system consists of a multi-stage cyclone, rotary kiln, and grate cooler.
- The kiln feed is preheated by hot gas from the combustion chamber and rotary kiln.
- Clinker formation takes place inside a rotary kiln which gets cooled inside the grate cooler.
- In the entire process, the components have to withstand high temperatures up to 1450°C.
