KHD Humboldt Wedag mills are space-saving, compact, high on performance and low on maintenance. This is primarily due to the support bearing design and the mill drive used. The mill is shell-supported, mounted on slide shoe bearings at both ends and made completely as a welded design. The mill with the compact drive version features an integral drive, whose planetary gear is mounted to the mill flange. KHD Humboldt Wedag mills are the result of the most advanced calculation and simulation methods, backed by years of experience. On a global level, the company has designed and built more than 1,000 tube mills. The standard KHD Humboldt Wedag mill is shell-supported on slide shoes and has a central drive. Torque transmission is effected via the conical discharge end. This cone is welded to the mill shell and has openings for the discharge of material and exhaust gases. The drive flange is connected to the end of the cone. In this way, the drive force is distributed directly and evenly to the mill shell.. The company’s mills for minimum space requirements are mounted on slide shoe bearings and have an integral drive. The core of this drive is a two stage planetary gear reducer, which is directly mounted on the end cone. Installation is fast and easy. No time consuming adjustments. The integral drive has 99% mechanical efficiency.To feature your products in this section, please contact V. Anand at +91 810 852 3000 or write to him at Anand@IndianCementReview.com

This strategic acquisition marks a significant investment in speciality alumina, a key step by Aditya Birla Group’s metals flagship towards becoming future-ready by scaling its high-value, technology-led materials portfolio.

Hindalco Industries, the world’s largest aluminium company by revenue and the metals flagship of the $28 billion Aditya Birla Group, has announced the acquisition of a 100 per cent equity stake in US-based AluChem Companies—a prominent manufacturer of speciality alumina—for an enterprise value of $125 million. The transaction will be executed through Aditya Holdings, a wholly owned subsidiary.

This acquisition represents a pivotal investment in speciality alumina and advances Hindalco’s strategy to expand its high-value, technology-led materials portfolio.

Hindalco’s speciality alumina business, a key pillar of its value-added strategy, has delivered consistent double-digit growth in recent years. It has emerged as a high-growth, high-margin vertical within the company’s portfolio. As speciality alumina finds expanding applications across electric mobility, semiconductors, and precision ceramics, the deal positions Hindalco further up the innovation curve, enabling next-generation alumina solutions and value-accretive growth.

Kumar Mangalam Birla, Chairman of Aditya Birla Group, called the acquisition an important step in their global strategy to build a leadership position in value-added, high-tech materials.

“Our strategic foray into the speciality alumina space will not only accelerate the development of future-ready, sustainable solutions but also open new pathways to pursue high-impact growth opportunities. By integrating advanced technologies into our value chain, we are reinforcing our commitment to self-reliance, import substitution, and building scale in innovation-led businesses.”

Ronald P Zapletal, Founder, AluChem Companies, said the partnership with Hindalco would provide AluChem the ability and capital to scale up faster and build scale in North America.

“AluChem will benefit from their world-class sustainability and safety standards and practices, access to integrated operations and a consistent, reliable raw material supply chain. Their ability to leverage R&D capabilities and a talented workforce adds tremendous value to our innovation pipeline, helping drive market expansion beyond North America.”

An Eye on the Future

The global speciality alumina market is projected to grow significantly, with rising demand for tailored solutions in sectors such as ceramics, electronics, aerospace, and medical applications. Hindalco currently operates 500,000 tonnes of speciality alumina capacity and aims to scale this up to 1 million tonnes by FY2030.

Commenting on the development, Satish Pai, Managing Director, Hindalco Industries, said the deal reinforced their commitment to innovation and global expansion.

“As alumina gains increasing relevance in critical and clean-tech sectors, AluChem’s advanced chemistry capabilities will significantly enhance our ability to serve these fast-evolving markets. Importantly, it deepens our high-value-added portfolio with differentiated products that drive profitability and strengthen our global competitiveness.”

AluChem adds a strong North American presence to Hindalco’s portfolio, with an annual capacity of 60,000 tonnes across three advanced manufacturing facilities in Ohio and Arkansas. The company is a long-standing supplier of ultra-low soda calcined and tabular alumina, materials prized for their thermal and mechanical stability and widely used in precision engineering and high-performance refractories.

Saurabh Khedekar, CEO of the Alumina Business at Hindalco Industries, said the acquisition unlocked immediate synergies, including market access and portfolio diversification.

“Hindalco plans to work with AluChem’s high performance technology solutions and scale up production of ultra-low soda alumina products to drive a larger global market share.”

The transaction is expected to close in the upcoming quarter, subject to customary closing conditions and regulatory approvals.
