Saurashtra Cement resolved frequent chute jams at its Gujarat plant by installing Martin® Typhoon Air Cannons, which significantly reduced downtime, manual labour, and safety risks. The solution improved operational efficiency, lowered costs, and enhanced worker safety, transforming the plant’s performance.

Solution: Martin® Typhoon Air Cannons

Industry: Cement

Location: Saurashtra Cement, Ranavav, Porbandar, Gujarat, India

Problem: In the bustling Saurashtra Cement Ltd plant in Ranavav, Gujarat, a relentless challenge emerged: chute jams disrupting operations every 3 to 4 hours, requiring arduous manual cleaning. This routine not only erodes operational hours but also incurs unnecessary costs. The dedicated workforce found itself trapped in a cycle of labour-intensive manual cleaning, giving rise to numerous safety risks. The operational team needed a solution to address the continuous chute blockages.

Air cannons prevent material build-up and minimise the need for manual cleaning.

Solution: The team at Saurashtra approached Martin’s expert team, who proposed a game-changing solution – an array of 10 Martin® Typhoon Air Cannons, each with a 70 litre capacity. Embracing this innovation, the plant management commissioned Martin to install Martin Typhoons to tackle the chute jamming challenge. The carefully timed compressed air bursts from these air cannons are designed to prevent material build-up and minimise the need for manual cleaning. This efficiency not only reduced downtime but also resulted in substantial cost savings and, most importantly improved health and safety for
the workforce.

Result: Implemented over the past year, the game-changing Martin® Air Cannons solution drastically reduced material buildups and blockages at the part of the plant. Manual interventions like poking and hammering are now relics of the past, replaced by the power of Martin’s innovation. The results exceeded expectations and in a short timespan the innovative Martin® Typhoon Air Cannons were a catalyst for a more efficient, cost-effective, and robust cement production process. Now the plant is seen as a beacon of efficiency and success, proving the transformative impact of the right solution.

Cement Firms to Invest Rs. 130 bn in Green Energy by FY28

Cement companies plan to expand clean energy capacity to 6 GW by FY28

India’s major cement companies are set to raise their clean energy capacity to 6 GW by March 2028 from around 4 GW at the end of March 2026, according to ratings agency ICRA. The planned expansion is expected to involve investments of Rs. 130 bn over the next two years.

The additional capacity could generate annual savings of Rs. 62 bn to Rs. 67 bn, resulting in an estimated payback period of 1.8 to 2.2 years. Cement is an emission-intensive industry, and leading producers have established net-zero roadmaps covering the next 15 to 20 years.

The calcination process accounts for 57 to 60 per cent of the sector’s total emissions, while fuel combustion contributes 27 to 30 per cent and electricity consumption accounts for 10 to 13 per cent. ICRA said the figures highlighted the need for a broad decarbonisation strategy involving green power, blended cement, alternative fuels and improvements in clinker efficiency.

Green energy is considered one of the most commercially attractive decarbonisation options because it can reduce emissions while lowering operating costs. Every 5 per cent increase in green power replacement can reduce power and fuel costs by Rs. 15 to Rs. 16 per tonne. A 25 per cent replacement level could therefore save Rs. 75 to Rs. 80 per tonne and expand operating margins by 140 to 160 basis points.

Cement producers are also assessing carbon capture, utilisation and storage, although high implementation costs, energy requirements and limited transport and storage infrastructure are expected to slow commercial adoption. The government has proposed Rs. 200 bn over five years to support deployment across key sectors. Meanwhile, companies are targeting thermal substitution rates of 10 to 15 per cent over the next three to five years, compared with the current industry level of around 6 per cent.
