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 Department of Civil Engineering at Dhanekula Institute of Engineering & Technology, Ganguru, organised an industrial interaction programme under the Adani FutureX Programme on Thursday. The programme focused on strengthening engagement between the institute and the cement industry while giving students greater exposure to professional practices.

Yedukondalu, technical head for Andhra Pradesh and Telangana at Adani Cement, delivered a technical lecture on concrete as a man-made material. The session covered the importance of concrete in construction, its properties and applications, and its significance in modern infrastructure development.

The lecture also addressed the role of quality cement and suitable concrete technology in supporting durable and sustainable construction. The discussion connected classroom learning with the technical considerations involved in infrastructure projects and construction practices.

A key part of the programme was the signing of a memorandum of understanding (MoU) between the Department of Civil Engineering and Adani Cement under the Adani FutureX Partnership Agreement. The agreement is intended to strengthen industry-academia collaboration through opportunities for student internships and industrial visits.

The initiative is expected to provide students with practical exposure, improve their understanding of industrial practices and help bridge the gap between theoretical knowledge and real-world applications. Dhanekula Institute Chairman Dhanekula Ravindranath Tagore, Secretary Dhanekula Venkata Bhavani Prasad and Director DKRK Ravi Prasad supported the initiative, with the institute leadership highlighting the importance of industry-institution interaction in enhancing students’ technical employability.

JK Lakshmi Cement has laid the foundation stone for Project Kamakshi, its first integrated cement manufacturing facility in Assam, marking the company’s entry into Northeast India. The groundbreaking ceremony took place at Umrangso village in Dima Hasao district in the presence of Assam Chief Minister Himanta Biswa Sarma.

The project involves an investment of Rs. 110 bn, including the mining lease. It will have annual cement production capacity of 2.5 mn t and a 1 mn t clinkerisation unit, with completion scheduled for FY2029.

The facility is expected to create more than 2,000 jobs and will primarily serve the growing Northeast market. It will also include dedicated railway sidings for transporting raw materials and finished cement, supporting supply chain reliability and regional distribution.

Chairperson and Managing Director Vinita Singhania said the project represented the beginning of a long-term relationship with Assam and the wider Northeast. She said the plant would help provide locally produced cement, employment and dependable supplies as the region’s infrastructure development accelerated, while enabling the company to grow alongside the communities it serves.

The investment supports JK Lakshmi Cement’s strategy of expanding into high-growth markets beyond its established presence in Northern, Western and Eastern India. The company expects the project to contribute to regional economic development and infrastructure growth while pursuing its long-term objective of achieving net-zero emissions by 2047.
