Gypsum board production line is a fully automated or semi-automated manufacturing system designed to produce gypsum boards, also known as plasterboards or drywall panels. These boards are widely used in construction, interior walls, ceilings, and partitions due to their fire resistance, durability, and ease of installation.
The production line integrates various processes, including gypsum powder preparation, board forming, drying, cutting, and packaging, ensuring efficient and high-volume output.
The specifications of a gypsum board production line vary based on production capacity, board dimensions, automation level, and processing technology. Below are the main specifications:
1. Production Capacity
Small-Scale Line: 2 to 5 million m²/year – suitable for local suppliers and smaller markets.
Medium-Scale Line: 5 to 10 million m²/year – ideal for regional suppliers with moderate demand.
Large-Scale Line: 10 to 50+ million m²/year – used by large-scale manufacturers for mass production.
2. Board Dimensions
Gypsum board production lines can manufacture boards in various sizes and thicknesses to meet different construction needs. Typical specifications include:
Length: 1800 mm – 4000 mm (6 ft – 13 ft)
Width: 900 mm – 1220 mm (3 ft – 4 ft)
Thickness: 6.5 mm – 15 mm (0.25 in – 0.59 in)
Custom Sizes: Production lines can be adjusted to create non-standard board sizes based on specific project requirements.
3. Raw Material Feeding and Mixing System
The production line includes an automated feeding system to handle raw materials such as:
Gypsum powder (CaSO₄·2H₂O)
Modified starch – enhances board strength.
Foaming agent – creates a lightweight core.
Accelerator and retarder – controls setting time.
Water and additives – ensure proper consistency.
Precision mixing systems guarantee consistent board quality by maintaining the optimal material ratio.
4. Board Forming and Shaping
The board-forming system consists of:
Forming Belt: A continuous moving belt that shapes the gypsum slurry into board thickness.
Edge Trimming System: Ensures clean, smooth edges by cutting excess material.
Thickness Control: Automated thickness adjustment for uniform board dimensions.
5. Drying System
The drying process is essential for removing moisture and solidifying the gypsum boards.
Drying Temperature: 180°C – 260°C (356°F – 500°F)
Drying Time: 30 – 60 minutes, depending on board thickness.
Drying Zone: Multiple drying sections ensure even moisture removal.
6. Cutting and Stacking
Once the boards are dried, they are:
Trimmed and cut to the required size using automatic saws.
Stacked and bundled for transportation and packaging.
Equipped with precise cutting systems to minimize waste and ensure clean edges.
7. Automation and Control System
Modern gypsum board production lines feature advanced automation for enhanced efficiency:
PLC Control System: Automated control of mixing, forming, and drying processes.
Touchscreen Interface: Allows operators to monitor and adjust production parameters.
Real-Time Data Logging: Tracks production metrics for quality assurance.
Gypsum board production line is an essential solution for mass-producing high-quality gypsum boards used in construction. With advanced automation, energy-efficient drying systems, and precise cutting technology, modern production lines offer superior efficiency, consistency, and profitability.
