SpectraFlow for Ramco plant

Published

Shares

Ramco Cements, an independent Indian group, ordered a Crossbelt and Airslide analyser from SpectraFlow analytics, for their new integrated plant at Kalvatala, to optimise the stability of their raw meal.

FLS was chosen as the main equipment supplier and Ramco project team looked after specialised components themselves and choose SpectraFlow Analytics Crossbelt analyser for their stockpile and pre-blending management and SpectraFlow Airslide Analyzer for raw meal optimisation of two raw mills.

The SpectraFlow Crossbelt analyser is the online analyser to be able to measure raw materials on belt conveyors. As raw materials from the quarry are processed through a crusher the raw material on the conveyor belt is statistically homogeneous and therefore the analytical results of the SpectraFlow Crossbelt analyser are accurate.

By using SpectraFlow Crossbelt analyser and a site specific blending strategy at Kavalatala the high variation in the local raw materials shall be balanced out to increase consistency of the stockpile quality.

Summarised benefits are:

– No need of sampling. Sampling from conveyor belts is unrepresentative and slow for process optimisation. Additionally, sampling is very work intensive regarding operation and maintenance.

– The analyser together with a pre-blending control software from Ramco Systems is fully automating the feed from the hoppers. The analyser delivers the analytical results and according the setpoint the software is adjusting the feeders into the mixing stage

– The analyser together with a pre-blending control software is informing the quarry/crusher operators of the current composition of the stockpile and accordingly the trucks can be coordinated to reach the setpoint of the stockpile.

– Stockpile quality will be homogeneous and on setpoint. That results in stable and low additive consumption at the raw mill.

– Stable feed from the stockpile leads to stable raw mill operation and fine raw meal/clinker quality.

The SpectraFlow Airslide analyser is the online analyser to be able to measure raw materials in airslides. As raw materials in airslides are very homogeneous and dry the analytical results of the SpectraFlow Airslide analyser are very accurate and based on these accurate results the raw mix control software can optimise the weight feeders before the raw mill in real time every minute. This results in very low LSF STDEV without the need of extensive sampling and laboratory efforts.

Kalvatala operates two roller press raw. The raw meal will feed to a joint airslide where the SpectraFlow Airslide analyser will measure. For the control of the weight feeders at the two raw mills Ramco will use control software from Ramco Systems. By using SpectraFlow an increase in the raw meal homogeneity will be achieved.

Summarised benefits are:

– Two raw mills can be controlled by one online analyser.

– No need of intensive sampling. No automated sample transport system, no automated laboratory required.

– High cost reduction due to reduced laboratory usage (capex, opex, manpower??

– The analyser together with the control software is fully automating the raw material grinding. The analyser delivers the analytical results and according the setpoint the software is adjusting the weight feeders of the additive bins.

– Adjustment of the weight feeders in real time every minute. No time delay due to sampling, sample preparation,

– Lower LSF STDEV/better and more consistent raw mill quality

This SpectraFlow order is the 39th order for the cement industry and the first installation in India. This order raises the installed based in India to

two analysers (one crossbelt and one airslide) and worldwide to 56 analysers (31 crossbelt and 25 airslide).

SpectraFlow Analytics, Switzerland are the experts in providing online analysis for the cement and minerals industry without any radioactive sources nor neutron generators. NIR technology used for

the SpectraFlow analyser is not requiring any permits or licenses and there are no restrictions in buying, importing or maintaining the analysers. This results in very low operating costs and high availability of the analysers combined with highly accurate measurement results.

The Brihanmumbai Municipal Corporation’s cement concretisation project, valued at Rs 170 billion (Rs 170 bn), has reduced expenditure on pothole repairs by 70 per cent over three years. Spending on repairs fell from Rs 2.02 billion in 2023–24 to Rs 1.56 billion in 2024–25 and then to Rs 890 million (Rs 890 mn) in 2025–26. The current tender is expected to be about Rs 440 million, representing a further 50 per cent reduction.

The project is being executed in two phases, with Phase I covering 307 km from October 2023 and Phase II covering 370 km from October 2024. The Indian Institute of Technology is auditing Phase II and will now also audit Phase I to ensure quality and accountability. Mumbai’s total road network spans approximately 2,050 km, of which about 1,200 km had been converted to cement concrete before 2022.

Since 2022 an additional 677 km were taken up for concretisation and nearly 71 per cent of that work, amounting to 481 km, has been completed. Municipal officials indicated that 10–15 per cent of the remaining work is expected to be completed by May 2026 and another 10 per cent by December 2026. The entire programme is scheduled for completion by May 2027, by which time nearly 1,900 km of Mumbai’s roads are expected to be fully concretised.

The administration has also developed a real time dashboard that displays detailed information about contracts, contractors and progress and citizens can access the latest updates online. The dashboard includes contact details for the civic officials and contractors responsible for particular roads to enhance transparency and accountability. The commissioner directed that ongoing works be completed by 31 May ahead of the monsoon to safeguard completion targets and minimise disruption.
