Ashwini Khunte, Regional Head – Sales and Marketing, Martin Engineering, discusses conveyor maintenance with advanced belt cleaning technology, which delivers durability, efficiency and safety for cement plants.

In every cement plant, a conveyor belt system forms the critical artery that moves material from raw feed to end product. That means conveyor performance is key to productivity and profitability.
Given that a cement plant can have well in excess of 100 conveyors, keeping belts running efficiently demands that they are well-maintained and remain free from carry-back, spillage and build-up that would otherwise cause excess wear and unscheduled down time.
Conveyors are also among the most dynamic and hazardous machinery within any processing plant, and manually inspecting and maintaining each component of a conveyor belt system across a wide area can also be time-consuming, labor intensive and, crucially, involves significant exposure to risk.
Even though the entire cement operation depends on conveyor performance, the importance of clean belts to overall productivity is rarely understood or prioritized by busy plant maintenance teams. Fortunately help is at hand, with specialists from Martin Engineering in available to help Indian cement producers to identify the root causes of their pain points and recommend innovative solutions that are proven to work.
As the world leader in bulk handling solutions, Martin Engineering recently marked 80 years of product innovation, engineering expertise and global growth. The company’s flagship Center for Innovation in Neponset, Illinois, USA is a hothouse for engineering research and technological advancement. As a result, Martin Engineering has become synonymous with the development and manufacture of innovations that deliver cleaner, safer and more productive bulk materials processing.

Unmatched belt cleaning
One of the many products by Martin that’s unique in the marketplace is the revolutionary CleanScrape® range of primary and secondary belt cleaners. In virtually every situation, CleanScrape outperforms all conventional scrapers, setting unrivalled standards for endurance, efficiency and reliability.
Featuring unique patented technology, CleanScrape is the most durable belt cleaning system available, delivering superior cleaning, whole-life cost reductions, and guaranteed to last four times the service life of conventional cleaners with a fraction of the maintenance time. Indeed, there are many cases where a much longer performance lifespan is achieved.
Installed diagonally across the discharge pulley, the blade forms a three-dimensional helix with a highly-effective but low contact pressure between belt and cleaner. The ‘blade’ is comprised of a matrix of tungsten carbide tips and is tensioned against the belt by cables, typically resulting in the removal of up to 95 per cent of stubborn material stuck to the belt.
Engineered for belt widths up to 120 in. (up to 3000 mm), speeds up to 1500 fpm (7.5 m/s), and pulley diameters of up to 78 in. (2000 mm), the cleaner’s groundbreaking design mean it requires minimal space for installation and also make it suitable for use on mechanical splices – put simply it’s the best performing and most versatile belt cleaner on the market.
The CleanScrape® Secondary Cleaner is a fully stainless steel assembly featuring independent 6-inch-wide blades with carbide tips. Each tip is supported on spring-loaded arms at both ends. The load springs allow independent blade rotation back and forward as well as up and down. This range of motion provides equal load pressure across each blade, absorbs obstructions, conforms to ever-changing belt undulations, and is able to arc safely in the event of belt rollback.
When used in combination, the CleanScrape® range of primary and secondary belt cleaners offers unparalleled belt cleaning performance. Carry-back, spillage and build-up are virtually eliminated, ensuring plants can run for way longer without stoppages, and maintenance frequency is much reduced allowing teams to focus on other priorities. But before jumping to conclusions about material handling problems, it’s always best to take a holistic approach. Martin Engineering’s team of experts work alongside maintenance teams and contractors to identify the root causes, specify the right solutions and deliver a return on your investment in improvement.

India’s pace of infrastructure development is pushing the construction sector to work at a significantly higher scale than previously. Tight deadlines necessitate eliminating concreting delays, especially in large and mega projects, which, in turn, imply installing the right batching plant and ensuring batching is efficient. CW explores these steps as well as the gaps in India’s batching plant market.

Choose well

Large-scale infrastructure and building projects typically involve concrete consumption exceeding 30,000-50,000 cum per annum or demand continuous, high-volume pours within compressed timelines, according to Rahul R Wadhai, DGM – Quality, Tata Projects.

Considering the daily need for concrete, “large-scale concreting involves pouring more than 1,000–2,000 cum per day while mega projects involve more than 3,000 cum per day,” says Satish R Vachhani, Advanced Concrete & Construction Consultant…

Andhra Offers Discom Licences To Private Firms Outside Power Sector

Policy allows firms over 300 MW to seek distribution licences

The Andhra Pradesh government will allow private firms that require more than 300 megawatt (MW) of power to apply for distribution licences, making the state the first to extend such licences beyond the power sector. The policy targets information technology, pharmaceuticals, steel and data centres and aims to reduce reliance on state utilities as demand rises for artificial intelligence infrastructure.

Approved applicants will be able to procure electricity directly from generators through power purchase agreements, a change officials said will create more competitive tariffs and reduce supply risk. Licence holders will use the Andhra Pradesh Transmission Company (APTRANSCO) network on payment of charges and will not need a separate distribution network initially.

Licences will be granted under the Electricity Act, 2003 framework, with the Central and State electricity regulators retaining authority over terms and approvals. The recent Electricity (Amendment) Bill, 2025 sought to lower entry barriers, enable network sharing and encourage competition, while the state commission will set floor and ceiling tariffs where multiple discoms operate.

Industry players and original equipment manufacturers welcomed the policy, saying competitive supply is vital for large data centre investments. Major projects and partnerships such as those involving Adani and Google, Brookfield and Reliance, and Meta and Sify Technologies are expected to benefit as capacity expands in the state.

Analysts noted India’s data centre capacity is forecast to reach 10 gigawatts (GW) by 2030 and cited International Energy Agency estimates that global data centre electricity consumption could approach 945 terawatt hours by the same year. A one GW data centre needs an equivalent power allocation and one point five times the water, which authorities equated to 150 billion litres (150 bn litres).

Advisers warned that distribution licences will require close regulation and monitoring to prevent misuse and to ensure tariffs and supply obligations are met. Officials said the policy aims to balance investor requirements with regulatory oversight and could serve as a model for other states.
