en.Wedoany.com Reported - MMD Group Limited (MMD), a manufacturer of bulk material crushing and handling systems, announced the delivery of two new Sizer Stations to the Mae Moh lignite mine operated by the Electricity Generating Authority of Thailand (EGAT), marking the successful completion of the latest phase in their long-term partnership. The mine is transitioning from traditional crushing processes to modern mineral sizer technology.
Sizer Station 6 and Sizer Station 7 were successfully handed over on June 19, 2026, marking another milestone in a partnership spanning over 30 years. Since 1993, MMD has delivered multiple sizer stations across various development phases of the Mae Moh mine, supporting one of Thailand's most important energy production projects.
The new project is part of EGAT's overall plan to upgrade its material handling systems. After relying on traditional double-roll crushers for approximately 40 years, EGAT first contacted MMD in 2014 to evaluate alternative technologies aimed at reducing maintenance requirements, improving reliability, and lowering operating costs while maintaining high production efficiency. The latest project was delivered following a long-term technical evaluation.
A key factor in EGAT's decision was the observed performance of MMD's sizer technology at Hongsa Power Company's operations. This large lignite mine-mouth power plant project, located near the Thailand-Laos border, features mining operations and equipment conditions broadly comparable to those at the Mae Moh mine. The equipment demonstrated high reliability, low energy consumption, and significantly reduced maintenance needs under similar operating conditions, reinforcing EGAT's confidence in deploying the technology across the Mae Moh mine.
Each new sizer station is designed with an average processing capacity of 1,500 tonnes of lignite per hour, equipped with an MMD 1000 Series Sizer, accepting a maximum feed size of 1,500 x 1,200 x 1,000 mm and producing an output size of 300 x 300 x 300 mm. The installation also includes associated feeding and conveying systems, providing EGAT with a complete in-pit sizer solution.
This project further solidifies MMD's position as a leading supplier of sizer stations in the region. Since 1993, MMD has supplied 20 of the 26 heavy-duty sizer stations installed locally, accounting for approximately 77% of the installed base. This market position reflects MMD's engineering capabilities and operational experience in large-scale mining applications.
The delivery of the Mae Moh project demonstrates MMD's approach of combining global engineering expertise with local execution capabilities. Manufacturing and engineering work was coordinated through MMD's international network, while local Thai partners supported steel structure fabrication and electrical control integration, ensuring the project was completed safely and on schedule.
Local engineers and project specialists from MMD Thailand played a crucial role in installation and commissioning, enabling rapid responses to on-site challenges, resolution of technical issues, and management of complex regulatory requirements.
Montree Pichayathana, Managing Director of MMD Thailand, stated that the project reflects the trust built through years of successful operations. EGAT adopted a comprehensive approach when evaluating new technologies, and the performance of MMD's sizer stations in nearby operations demonstrated high reliability, low maintenance requirements, and long-term operational value. He expressed pride in completing the latest phase of the Mae Moh project, highlighting the technical capabilities, the strength of the global engineering network, and the commitment of the local Thai team and partners.
Since 1993, MMD has continuously supported the evolution of the Mae Moh mine through various development stages, with each installation improving material handling reliability and efficiency. The latest project represents a continuation of this long-term partnership and the ongoing modernization of one of Southeast Asia's most important lignite mines. As mining operators increasingly focus on improving productivity, reducing maintenance needs, and lowering total cost of ownership, the Mae Moh project demonstrates the long-term value of modern mineral sizer technology in large-scale applications.
