Geogrid is a high-performance material widely used in civil engineering, mainly used to enhance soil, prevent landslides, and reinforce roadbeds. The technical parameters of the geogrid production line equipment directly affect the quality, production efficiency, and production cost of the products. The following are the main technical parameters and detailed descriptions of the geogrid production line equipment:

1. Production line type

Unidirectional and bidirectional geogrid production line: suitable for producing unidirectional or bidirectional tensile geogrids. Unidirectional grilles are mainly used in unidirectional stress situations, such as roadbed reinforcement; Bidirectional grilles are suitable for bidirectional stress situations, such as foundation treatment.

3D geogrid production line: used for producing geogrids with 3D structures, which have better three-dimensional support effects and are suitable for complex terrains and special engineering requirements.

2. Production capacity

Production speed: usually expressed in meters per minute (m/min) or tons per hour (t/h). The speed of ordinary geogrid production lines is between 10-30m/min, while high-speed production lines can reach speeds of over 50m/min.

Annual output: Depending on equipment specifications and operating time, the annual output can range from several hundred tons to several thousand tons. For example, a medium-sized production line has an annual output of approximately 2000-5000 tons.

3. Raw materials

Raw material types: Common raw materials include high-density polyethylene (HDPE), polypropylene (PP), polyester (PET), etc. Different materials have different mechanical properties and weather resistance.

Raw material specifications: The particle size, melt index (MI), and other parameters of the raw material must meet production requirements. For example, the melt index of HDPE is usually between 0.5-2.0g/10min.

4. Equipment composition

Extruder: used to melt and extrude raw materials into sheets. The main parameters include screw diameter (such as 90mm, 120mm), aspect ratio (such as 30:1), heating power (such as 30kW), etc.

Rolling machine: Roll the molten sheet into the desired thickness. The main parameters include roller diameter (such as 500mm), roller length (such as 2000mm), rolling speed (such as 10-30m/min), etc.

Stretching machine: Stretching the sheet in one or both directions to form a grid structure. The main parameters include stretching ratio (such as 1:5), stretching speed (such as 10-20m/min), stretching force (such as 10-20kN), etc.

Cooling system: used to cool the stretched grille and ensure its dimensional stability. The main parameters include cooling water temperature (such as 10-20 ℃), cooling water flow rate (such as 10m ³/h), etc.

Cutting machine: Cut the continuously produced grille into the required length. The main parameters include cutting accuracy (such as ± 1mm), cutting speed (such as 10-20m/min), etc.

Winder: Roll the cut grille into a roll. The main parameters include winding diameter (such as 1000mm), winding speed (such as 10-20m/min), etc.

5. Control system

Automation level: Modern geogrid production lines usually use PLC (programmable logic controller) and touch screen for automation control, achieving precise monitoring and adjustment of the production process.

Temperature control: The temperature control accuracy of equipment such as extruders and calenders is usually within ± 1 ℃, ensuring stable product quality.

Speed control: The speed of each device needs to be synchronously controlled to ensure the continuity and consistency of production. The speed control accuracy is usually within ± 0.1m/min.

6. Energy consumption

Total power: The total power of a medium-sized geogrid production line is usually between 200-500kW, depending on equipment specifications and production capacity.

Energy efficiency: By optimizing equipment design and control strategies, the energy consumption per unit of product can be reduced and production efficiency can be improved. For example, using energy-saving motors and frequency converters can reduce energy consumption by 10-20%.

7. Product specifications

Grille size: including the width (such as 1-6 meters), length (such as 50-100 meters), thickness (such as 1-5 millimeters), etc. of the grille.

Mesh size: The mesh size of the grille is usually between 10-50 millimeters, depending on the engineering requirements.

Tensile strength: The tensile strength of unidirectional grids is usually between 20-100kN/m, while the tensile strength of bidirectional grids is between 10-50kN/m.

8. Equipment size and weight

Production line length: The length of a complete geogrid production line is usually between 30-50 meters, depending on the equipment configuration.

Equipment weight: The total weight of the production line is usually between 20-50 tons, depending on the equipment specifications and materials.

9. Environmental requirements

Factory area: The installation of the production line requires sufficient factory area. It is usually recommended that the length of the factory be no less than 50 meters, the width be no less than 10 meters, and the height be no less than 5 meters.

Temperature and humidity control: The production environment needs to maintain a certain temperature and humidity, usually between 20-30 ℃ and 50-70%.

10. Maintenance and upkeep

Maintenance cycle: Regularly maintain and upkeep the equipment to ensure its normal operation. It is usually recommended to perform minor maintenance every 500 hours and major maintenance every 2000 hours.

Replacement of vulnerable parts: such as extruder screws, rolling mill rollers, and other vulnerable parts need to be regularly inspected and replaced to ensure production quality.

The technical parameters of the geogrid production line equipment cover all aspects from raw material processing to final product packaging. Reasonably selecting and configuring these parameters can not only improve production efficiency and product quality, but also reduce production costs and energy consumption. When selecting production line equipment, enterprises should consider various technical parameters comprehensively based on their own needs and engineering characteristics, and choose suitable production equipment.
