Pressurized Refining Systems for Medium-Density Fiberboard Production

Greenply Speciality Panels Pvt. Ltd. has placed a repeat order with ANDRITZ for a pressurized refining system used in medium-density fiberboard processing. This deployment introduces high-capacity mechanical fiber separation technologies to continuous industrial wood processing operations.

Operational Scaling in Wood Panel Manufacturing
Targeting the industrial wood processing sector, Greenply Speciality Panels operates production facilities supplying medium-density fiberboard to domestic and international markets. To support scaling production capacities and manage continuous material processing demands, the facility required robust mechanical refining infrastructure. ANDRITZ functions as the technology provider, supplying the engineering hardware necessary to handle continuous throughput while minimizing equipment degradation. The integration of a second system addresses the need for parallel processing capacity and operational redundancy at the manufacturing site.

Pressurized Refining Architecture and Component Integration
ANDRITZ is responsible for supplying a complete pressurized refining system engineered for a throughput capacity of 25 metric tons per hour. The technical architecture centers on an S 1056 refiner coupled with a pressurized digester, which thermally and mechanically processes raw wood chips into uniform fibers. Material intake is managed by a C-Feeder system and a plug screw feeder. To mitigate the abrasive nature of continuous wood processing, the screw feeder is fitted with AdvaProtect wear segments. This application extends the operational lifespan of the feeder components by increasing resistance to mechanical friction.




Facility Implementation and Process Stability
The system is being deployed at the Greenply Speciality Panels facility located in Vadodara, Gujarat, India. The integration of this 25-ton-per-hour line runs parallel to existing plant infrastructure to increase total site output and support the underlying digital infrastructure of the plant's control systems. ANDRITZ provides the primary equipment and technical specifications, while Greenply oversees site integration to ensure the new refining loop synchronizes with downstream pressing and forming stages.

The deployment of this specific refiner configuration is structured to stabilize fiber quality and reduce maintenance downtime through the application of wear-resistant feeder components. The mechanical and thermal mechanisms integrated into the system are designed to yield consistent product quality and maintain efficient operation rates during continuous manufacturing cycles.
