Gypsum board, as a widely used lightweight partition and ceiling material in modern architecture, cannot be produced without professional complete sets of equipment. A complete gypsum board production line is usually composed of equipment for raw material processing, molding, drying, cutting, packaging and other links. This article will provide a detailed introduction to the main components and functions of a complete set of gypsum board equipment.
1、 Raw material processing equipment
The main raw materials for gypsum board are natural gypsum (or industrial by-product gypsum), water, additives, etc. The raw material processing equipment mainly includes:
Crusher: used to crush block gypsum into small particles for subsequent grinding.
Grinding machine: further grind the crushed gypsum to the specified fineness (usually 80-150 mesh) to ensure the uniformity of the gypsum slurry.
Ingredient system: including electronic scales and mixers, used for precise proportioning of gypsum powder, water, additives (such as starch, foaming agents, etc.).
Blender: Mix the raw materials thoroughly to form a uniform gypsum slurry.
2、 Forming equipment
Forming is the core process of gypsum board production, and the main equipment includes:
Slurry distributor: evenly distribute the mixed gypsum slurry onto the forming conveyor belt.
Forming conveyor belt: usually uses stainless steel mesh belt to carry the slurry and transport it to the next process.
Forming mold: determines the thickness and width of gypsum board, usually using adjustable design to adapt to different specifications.
Pre compaction device: perform preliminary compaction on the initially formed gypsum board to improve density and strength.
3、 Drying equipment
After the gypsum board is formed, the moisture needs to be removed, and the drying equipment is the key:
Multi layer dryer: using hot air circulation method, usually divided into multiple temperature zones (such as preheating zone, high temperature zone, cooling zone), gradually reducing the moisture content of gypsum board.
Hot air system: The heat source is provided by a combustion furnace (gas or coal) or electric heating to ensure drying efficiency.
Exhaust gas treatment system: filters the dust and harmful gases generated during the drying process, meeting environmental protection requirements.
4、 Cutting equipment
The dried gypsum board needs to be cut according to standard dimensions, and the main equipment includes:
Vertical cutting machine: Cut gypsum board into standard sizes (such as 1200mm, 2400mm, etc.) along the length direction.
Horizontal cutting machine: Cut gypsum board in the width direction to meet different customer needs.
Waste edge recycling system: Collect the scraps generated by cutting, which can be re ground and reused to improve the utilization rate of raw materials.
5、 Packaging and Stacking Equipment
The finished gypsum board needs to be packaged and stacked, and the main equipment includes:
Automatic packaging machine: using plastic film or cardboard packaging to improve transportation efficiency.
Stacker crane: Automatically stacks packaged gypsum boards for easy forklift handling.
Conveyor belt system: connects various processes to achieve automated production.
6、 Summary
A complete set of gypsum board equipment covers raw material processing, molding, drying, cutting, packaging and other links. The higher the degree of automation, the more stable the production efficiency and product quality. With the increasing demand for environmental protection, modern gypsum board production lines also focus on energy conservation, consumption reduction, and waste gas treatment to meet green production standards. Whether it is building a new production line or upgrading equipment, choosing the appropriate complete set of equipment is crucial for gypsum board production enterprises.
