Next-generation production technologies deliver benefits today

The future has arrived. Forward-thinking panelboard producers are taking advantage of innovative new features on new systems that can also be retrofitted to existing equipment.

Accelerating the development of new capabilities and implementing these innovative features make ANDRITZ a global technology and service leader, headquartered in Austria. Innovations in thermal and electrical energy savings, IIoT connectivity, and smart-plant networks are part of our company’s offering for new ‘front-end’ systems. These capabilities can also be retrofitted into existing installations.

Energy down, throughput up

Reducing energy consumption is a key cost factor for any MDF producer. Studies show, that about 70% of the energy demand is thermal energy, so technology that reduces thermal energy consumption can have a significant payback and positive global impact in reducing the use of fossil fuels.

Center steaming for high-capacity plants 

Center steaming ensures the best pretreatment of wood chips before they enter the digester. ANDRITZ is the market leader in supplying high-capacity systems (up to 80 bdmt/h).

Smart plug screw feeders

ANDRITZ plug screw feeders achieve the highest dewatering efficiency even for incoming raw materials with high moisture content. The compression ratio and diameter of the screw can be customized to any application. The cylindrical shape of the plug screw creates the industry’s largest amount of open area for dewatering.

Stream recovery system (SRS)

The SRS system allows the reuse of excess steam by returning it from the blowline after the refiner to the pre-steaming bin.

New steam regulation module for effective heat utilization (SRM)

The latest innovation in SRM helps to maximize thermal transfer and lower the overall consumption. The new module does the counter-current flow into the digester based on online temperature measurements, achieving a very stable temperature in the digester. This ensures the best chip quality in terms of moisture, color, and temperature before the chips are refined.

Advanced wear resistance for longer life

Even though the quality of fibrous raw materials is declining, the demands for quality of the end product are increasing, making the machinery a subject to more wear, even as throughput increases. By adding advanced wear protection in the pressurized refining system and embedding sensors in the feeder to monitor bar wear, screw condition, and screw deflection ANDRITZ provides solutions to offset the potentially high wear due to pressurized flows and abrasive raw materials. The innovative plug screw feeder mentioned above monitors screw condition online, so that replacement of the critical wear components can be scheduled as precisely as possible.

IIoT tools for predictive maintenance and
optimal operation

ANDRITZ is very active in developing solutions compatible with the Industrial Internet of Things (IIoT) including its innovative ANDRITZ Maintenance Interval GuideOrganizer (AMIGO) to help maintenance personnel increase their efficiencies and lower their costs (e.g., automating cleaning sequences; monitoring the wear of critical components; condition monitoring of bearings, lube, and cooling water systems; refiner plate pattern recognition). In addition, there are new SMART products to improve product performance, such as dewatering efficiency and steam recovery. Connected in a proper way, these IIoT solutions contribute to complete autonomous plant operation.
