The worldwide commercial and residential construction sectors continue to require lightweight, fire-resistant, and sustainable drywall materials. When an international building materials conglomerate sought to scale its manufacturing footprint, they evaluated top gypsum board machinery manufacturers capable of delivering a high-output, fully automated facility. The target was to establish a greenfield plant with an annual capacity of 30 Million Sqm (square meters). Executing a project of this scale overseas presents significant engineering hurdles. These include managing precise liquid-to-solid slurry dosing at continuous high line speeds, preventing board delamination during high-speed transfer, and keeping natural gas consumption manageable during thermal drying. To ensure seamless long-term operation, the client awarded Hebei Lvjoe Machinery Manufacturing Group Co., Ltd. the complete turnkey EPC contract.
Achieving superior board strength and smooth surface finishes starts at the wet-end raw material preparation zone. Hebei Lvjoe Machinery designed a continuous dosing system equipped with automated loss-in-weight gravimetric feeders. These feeders continuously measure calcined synthetic gypsum, starch, fluidizing agents, and liquid foaming additives directly into a proprietary high-shear continuous mixer. The resulting homogenous slurry is evenly spread between top and bottom high-tensile protective paper liners. Servo-driven forming stations calibrate board thickness and edge profiles with tight tolerances before the continuous ribbon enters the setting belt conveyor. By ensuring exact material metering early in the process, the plant eliminates core density fluctuations and reduces raw material waste during high-speed manufacturing runs.
Once the hydrated gypsum slurry achieves optimal structural rigidity on the long-distance setting belt, high-frequency flying shears perform precise, burr-free transverse cuts. The wet boards are then automatically accelerated and distributed into a multi-tier, multi-deck drying chamber. In plasterboard production, thermal drying represents one of the highest continuous operational expenditures (OPEX). As one of the experienced gypsum board machinery manufacturers, Hebei Lvjoe Machinery implemented a multi-stage waste heat recovery system into the drying section. Exhaust air from hot drying zones is recaptured to preheat incoming fresh process air, noticeably cutting natural gas consumption per square meter.

Deploying heavy industrial equipment overseas demands meticulous field installation and system calibration. Hebei Lvjoe Machinery dispatched a senior engineering team to supervise civil foundation alignment, heavy structural erection, and network cabling. A Distributed Control System (DCS) serves as the central brain of the facility, gathering data from field sensor nodes. During commissioning, engineers fine-tuned closed-loop control protocols to handle real-time operational variables:
Dynamic Viscosity Adjustments: Automatically adjusting water-to-gypsum ratios based on raw material purity shifts.
Line Velocity Synchronization: Matching setting belt speeds perfectly with cutter cycles and dryer feeder trays.
Multi-Zone Temperature Profiling: Balancing crossflow hot air volume and humidity levels across every tunnel level.
This integrated cloud-enabled architecture allows for 24/7 remote diagnostic tracking, establishing operational stability from the first production shift.
Within weeks of initial system ignition, the 30 Million Sqm annual capacity facility reached full design speed. Finished plasterboards easily exceeded international building benchmarks, including ASTM C1396 standards in North America and EN 520 European regulations for flexural strength, nail pull resistance, and core cohesion. Partnering with Hebei Lvjoe Machinery Manufacturing Group Co., Ltd. provided the client with a streamlined project delivery schedule, an accelerated payback period driven by reduced thermal energy usage, and long-term operational guarantees backed by priority spare parts dispatch. This successful deployment reinforces how expert manufacturing partners deliver measurable value to building materials producers worldwide.
An end-to-end turnkey EPC project—encompassing engineering design, machinery fabrication, international shipping, civil alignment, physical erection, and DCS calibration—typically requires 6 to 9 months, depending on local site readiness and foundation preparation.
Energy savings are achieved by integrating patented waste heat recovery systems into the multi-deck drying chamber. Reclaiming high-temperature exhaust air to preheat fresh process air, combined with variable-frequency circulation fans and heavy insulation casings, lowers total natural gas consumption significantly.
Plasterboards manufactured on Hebei Lvjoe Machinery’s automated equipment comply with major global specifications. This includes full compliance with ASTM C1396 (North America) and EN 520 (Europe) for core density, edge profile uniformity, and fire resistance.
