Amarkant Pandey, Deputy General Manager (Process), Prism Johnson (Cement Division), Satna, presents a case study on capacity enhancement of clinker production in an existing kiln.

This case study outlines the strategic initiatives taken to enhance production capacity of Prism Johnson (Unit-2) from 8000 TPD to 9100 TPD. This would help the company to expand its market share, develop new products and fortify our position in the cement industry.
With a consistent increase in regional demand and a positive market outlook, it was imperative for Prism Johnson’s Unit-2 to augment its production capacity from 8000 TPD to 9100 TPD in FY 2020-21. This enhancement aligned with our commitment to provide high-quality cement products while maintaining operational efficiency.

Cement capacity and production
The production capacity of Prism Johnson’s Unit-2 in FY-21 was at 8000 TPD. The plant was operating close to full capacity, with production data indicating steady growth trajectory, and it was evident that the current capacity was reaching its limits, thereby necessitating the need for expansion.
New capacity: The project entailed increasing the production capacity from 8000 TPD to 9100 TPD, thereby accommodating the rising market demand.
Timeline: The project was anticipated to span across 60 days.
Technology and process improvements: To optimise efficiency, the capacity enhancement project incorporates state-of-the-art technologies and process improvements. These advancements aim to reduce energy consumption, enhance product quality and ensure sustainable production practices.
The following technical upgradations has been implemented in order to support the upgraded production:

1. Kiln feed transport bucket elevators 352.BE250 and BE340 were upgraded (to 723 tph) to increase kiln tonnage.
2. Preheater ID Fans (2) were retrofitted to suit 9100 TPD.
3. Kiln feed rotary valves, ID Fan motors and VFDs have been changed.
4. Cooler was upgraded from SF 5×6 to SF-CB 5×7 (177 to 206 m2 grate area).
5. Clinker crusher was changed from hammer to heavy duty roller breaker HRB MF-418.
6. Expansion of kiln riser duct and connection of TAD to calciner.
The areas where major upgradations took place are highlighted in these figures:
Risk assessment: Potential risks, including construction delays, regulatory approvals and associated delays, and market fluctuations, have been identified. A comprehensive risk mitigation strategy is in place to address and minimise these challenges.
Performance evaluation: Kiln started operating in January 2023 following the upgrade. We encountered several problems with M/s FLS’s cooler hydraulics. In January and February of 2023, a new hydraulic system was installed to replace the entire one. Kiln has produced 9100 TPD of clinker since April 2023. The plant performance before and after upgrading is tabulated below.
The chart indicates that an increase in clinker production resulted in a specific heat consumption reduction of around 5 Kcal/kg of clinker.
Presently, kiln volumetric loading is about 7.0, which is significantly higher than what is specified in the design. Additionally, with enhanced clinker production, we are meeting all quality targets (C3S, litre weight, free lime, etc.) for the clinker.

Challenges
• Crushed limestone size: Limestone size was in the higher side (+100mm to 5 per cent) and the gap between blow bar tip and lower grinding path was adjusted at 50mm previous the same was 70mm
• Pile homogeneity: The homogeneity of the pile was the biggest challenge due to huge variation in the mine’s limestone quality (6 different sources of mines). We increased the stacker speed from 11m/s to 13m/s to get better homogeneity. Also, CBA was installed to control variation in input materials from mines and standard deviation of pile was reduced from 80 to 20.
• Raw mills output: To fulfil raw meal requirements with increased kiln production, various modifications were done in the raw mill like replacement of old nozzle rings with new design nozzles etc.
• Kiln burner replacement: Old duo flex burner replaced with Pyrojet burner to reduce frequent snowman formation, increase utilisation of high sulphur petcoke and enhance flame quality.

Conclusion
The capacity enhancement by modification from 8000 TPD to 9100 TPD is a strategic move for Prism Johnson. It positions the company to meet market demands efficiently, contribute to regional development, and ensure the long-term sustainability and competitiveness of our operations.

UltraTech Cement Ventures into Wires and Cables with Rs 18 Bn Plan

The New Gujarat Plant Marks Expansion in Construction Value Chain.

UltraTech Cement has announced its foray into the wires and cables segment, further expanding its footprint in the construction value chain. The Aditya Birla Group company will invest Rs 18 billion in setting up a state-of-the-art manufacturing facility near Bharuch, Gujarat, which is expected to commence operations by December 2026. An initial investment of Rs 1 billion has already been made towards the project.

The UltraTech board of directors approved the strategic expansion, reaffirming the company’s commitment to strengthening its position as a comprehensive building solutions provider. This move follows last year’s entry into the decorative paints sector with the launch of Birla Opus, signalling the company’s diversification beyond its core cement business.

Strategic Market Entry and Growth Potential
UltraTech Cement aims to tap into the growing demand for wires and cables across residential, commercial, infrastructure, and industrial sectors. The wires and cables industry in India has witnessed a robust revenue growth of approximately 13% between FY2019 and FY2024, driven by rising urbanisation, infrastructure development, and increasing adoption of branded products over unorganised players.

UltraTech believes its entry into this high-growth sector will be value accretive for its shareholders, presenting a compelling opportunity to establish a credible, large-scale presence in the organised market.

Core Cement Business Remains a Priority
Despite this diversification, UltraTech Cement remains firmly committed to its core cement business. The company recently achieved a milestone cement production capacity of over 175 million tonnes per annum (mtpa) in India. It continues to strengthen its leadership position through strategic acquisitions and capacity expansions, especially amid intense competition from Ambuja Cements, owned by the Adani Group.

Industry Outlook: A Diversified Future for Construction Materials
The construction materials industry in India is witnessing rapid evolution, with companies increasingly diversifying their portfolios to cater to a growing and dynamic market. With infrastructure development and urbanisation on the rise, demand for complementary building materials such as wires, cables, and paints is expected to surge. UltraTech’s strategic expansion aligns with this trend, positioning it to capitalise on emerging opportunities while reinforcing its leadership in cement manufacturing.
