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.

Dalmia Cement (Bharat) Limited (DCBL) executed a business transfer agreement on 21 May 2026 to acquire a cement undertaking from Jaiprakash Associates Limited (JAL) and Adani Infra (India) Limited. The assets include plants at Rewa in Madhya Pradesh and Churk, Chunar and Sadwa in Uttar Pradesh with five point two million tonnes per annum (mn tpa) cement capacity and three point three mn tpa clinker capacity, plus 99 megawatt (MW) thermal power and railway sidings. The transaction carries an enterprise value of Rs 28.5 billion (bn).

DCBL, a wholly owned subsidiary of Dalmia Bharat Limited (DBL), will see cement capacity rise to 54.7 mn tpa on completion. Ongoing expansions at Belgaum, Pune and Kadapa are expected to raise capacity to 66.7 mn tpa by the second to third quarter of fiscal 2028. The company said the transaction would be consummated within two weeks.

The deal follows a framework signed in December 2022 to settle long running disputes with JAL, including a long term clinker supply arrangement. Completion was delayed when JAL entered insolvency and the earlier sale did not finalise. Following approval of a resolution plan under the Insolvency and Bankruptcy Code, DCBL executed a fresh business transfer agreement to resolve pending legal and arbitral matters.

Company statements described the acquisition as strategic, accelerating access to central markets compared with a greenfield route and offering scope for expansion through debottlenecking and brownfield investment. Proximity to the company’s captive mines and established vendor relationships should support faster ramp up. The assets should augment EBITDA delivery and enhance returns by enabling entry into newer markets with relatively better prices.

Senior executives said the addition aligned with a long term plan to build a pan India presence and would provide a head start in central markets. They noted that familiarity with the plants under earlier tolling arrangements offers operational insight and strengthens channel relationships, supporting quicker market entry. Management expressed confidence that the assets’ expansion potential would generate value for stakeholders.

The transaction is expected to be completed within two weeks.

Dalmia Cement had entered into a framework agreement with Jaiprakash Associates in December 2022 for the sale of business assets and related agreements, including a business transfer agreement and cement sale purchase agreement. The agreements were intended to settle disputes between the parties, including those under the long-term clinker supply agreement. However, the transaction could not be completed after Jaiprakash Associates was admitted to insolvency.

Following approval of the Adani Group’s resolution plan for Jaiprakash Associates under the Insolvency and Bankruptcy Code, Dalmia Cement requested that the earlier agreement be considered to settle pending disputes. The company has now executed a fresh Business Transfer Agreement with Jaiprakash Associates and Adani Infra (India) for the cement undertaking.

The acquisition supports Dalmia Bharat’s strategy to become a pan-India cement player and provides faster access to Central markets compared to a greenfield project. The assets also offer expansion potential through debottlenecking and brownfield development.

Puneet Dalmia, Managing Director and CEO, Dalmia Bharat, said the assets are a strong strategic fit and will help the company serve high-potential markets in the Central region. He added that the expansion potential of the assets and their proximity to Dalmia’s captive mines could help create a future capacity hub.
