India: Operators of limestone mines in Karnataka's Chamarajanagar District have suspended quarry operations indefinitely in protest against the Karnataka state government's increased licensing royalties and rules requiring drone surveillance. The companies also demand that the state government cease to implement new policies affecting them. The Times of India newspaper has reported that the strike has impacted a total of 10,000 jobs, both at quarries and downstream in the building materials and construction sectors.

India: Dow Jones Institutional News has reported that Adani Group is in talks with a ‘major shareholder’ of Orient Cement over a possible acquisition of the latter’s stake in the CK Birla Group company.

Orient Cement first began producing cement in Telangana in 1982, and has since spread to Karnataka and Maharashtra, with a cement production capacity of 8Mt/yr.

Orient Cement previously leased land in Maharashtra for a new grinding plant from coal-fired power plant Adani Power Maharashtra, an Adani Group subsidiary, in late 2021. Adani Group entered the cement sector following its acquisition of ACC and Ambuja Cements from Switzerland-based Holcim on 16 September 2022.

India: Indian cement producers imported four shipments with a total of 160,000t of petcoke from Venezuela during the first quarter of the 2023 financial year. Reuters News has reported that a fifth shipment of 50,000t of petcoke is due to arrive in Mangaluru, Karnataka, in mid-August. A further, 30,000t, delivery is also scheduled for shipment from Venezuela during the month. Shipping takes around 50 days.

Ramco Cements enjoyed a US$15 – 20/t discount on its two 50,000t shipments of Venezuelan petcoke in June and July 2022, for which it paid US$10.7m and US$11.1m respectively. Its chief financial officer Sivaraman Vaithiyanathan said
"The quality of petcoke is very good and it has very low sulphur."

India: Chettinad Cement has ordered a MVR 5600 R-6 type mill for raw meal grinding and a MVR 5300 C-6 type mill for grinding composite cements from Germany-based Gebr. Pfeiffer for a new production line at its integrated Kallur plant in Karnataka. The supplier says that the MVR 5600 R-6 type mill is the first of its kind provided with six rollers. The order was placed in April 2022 and the contract has since been activated with the receipt of down-payment and a letter of credit.

The core components of the MVR mills as well as the 5810 kW gearbox will be supplied by Gebr. Pfeiffer SE from Europe. Foundation parts, housings and other components will be manufactured in India and delivered to the customer under responsibility of its subsidiary Gebr. Pfeiffer (India). The office of Gebr. Pfeiffer (India) in Noida, near New Delhi, will also support the end customer in plant design, procure most of the grinding plant machinery such as filters, fans, hot gas generators, the fly ash handling and conveying aggregates, and will be on site with personnel for quality control of the customer's site fabrication as well as supervision of erection and commissioning.

India: Dalmia Cement (Bharat) plans to invest US$38.9m in an upgrade to 2.5Mt/yr Belagavi cement plant. The work will consist of a capacity expansion and the installation of a new 9MW solar power plant at the facility. The latter is expected to halve the plant's grid electricity consumption. When commissioned in March 2024, the expanded plant will directly and indirectly employ 700 additional people.

India: Aumund Engineering India has been selected by ACC to refurbish a 175.3m high bucket elevator, the tallest in the world. The elevator is installed at ACC’s Wadi Cement plant in Karnataka where it is used for raw meal pre-heater transport at a rate of 600t/hr.

Originally, the machine was fitted with a steel cord belt of width 1320mm and tension rating of 3150N/mm. Aumund has decided to offer an alternative based on its own design concept resulting in a belt width of 1300mm but with higher tension rating of 4000N/mm with a bucket size of 1250mm at bucket spacing of 450mm. The Aumund belt concept will use continuous close pitch longitudinal ropes without rope free bucket mounting spaces. However, it will use additional wire ropes running laterally across the width of the belt adding lateral stiffness without significantly changing the belt longitudinal flexibility. This cross-stabilised construction is intended to improve stability to the belt with improved bucket fixing.

To make the necessary belt punching, Aumund has developed a special punching machine design which gives clean fixing holes that are accurately aligned relative to the belt edge and at precisely the correct pitch. The belt is held in a cassette and advanced automatically under the punching frame using a precision encoder to measure the pitch. The belts are prepared at the Aumund production in Rheinberg, Germany and shipped to site at the exact required dimensions including a prepared joint and the required clamping connection.

In addition to the new belt the elevator will also be fitted with new drive pulley including friction linings and rubber bucket mounting strips. The casings, inlet and outlet plus the complete drive unit remain unchanged.
No commissioning date for the project has been announced.

India: Shree Cement is on track to commission its 3.0Mt/yr cement grinding plant at Patas in Pune, Maharashtra in September 2021. The plant was originally scheduled for commissioning in late 2020 but this was delayed due to Covid-19 led-disruption. The unit has had an investment of around US$80m and it will source clinker from a group site in Karnataka. The plant is Shree Cement’s first in western India.

India: JSW Cement has launched a new set of products in the construction chemicals sector. These will include floor hardeners, waterproofing compounds and readymix plaster. The company’s 0.3Mt/yr chemical plant at Ballari in Karnataka is supporting the move.

Construction Chemicals business head Mubin Hussain said "With advances in green product technologies, this sector will see a dynamic shift from conventional construction mix ratios to extracted by-product engineered compositions. Construction chemicals and dry mix mortars are expected to grow fourfold by the 2025 financial year."
