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.
A key concern of any cement plant is the availability of critical processing equipment, including crushing/grinding machines and a vertical roller mill (VRM). VRM is well known in the cement industry as the preferred mill for grinding raw meal coal slag and clinker. The downtime during repair is a high cost, and there are continual efforts to reduce this time to resume full production status. In Situ Repair Welding of rollers and tables is an efficient way to extend the life of the VRM as it helps in the following.
Crushers are vital equipment in the cement industry as the manufacturing process starts by crushing raw materials like limestone, coal, dolomite, gypsum, etc. The size reduction of raw materials is affected in at least two main stages:
The cement industry is one of the leading markets for industrial fans. Fans are heavy duty and perform two essential functions, as follows.
