High End Exterior Wall Rock Wool Board Production Line

The modern high-end rock wool board production line adopts a multi station integrated design, realizing the full process automation from raw material processing, 3D pendulum forming to composite pressing. Through modular line compatibility technology, it is possible to quickly switch the production of rock wool/PU/PIR composite panels. The surface layer supports diverse combinations such as color steel, aluminum foil, and cement base fabric, adapting to different scene requirements such as building curtain walls and cold storage.

A complete high-end exterior wall rock wool board production line consists of multiple precision coordinated subsystems, each of which directly affects the quality of the final product.

Equipment composition and functional characteristics:

Raw material processing and melting system

• Automatic raw material proportioning system: Using a computer-controlled weighing feeding device, basalt, slag and other raw materials are mixed in precise proportions with an error controlled within ± 0.5% to ensure stable chemical composition. The high-quality production line will also add modifiers such as dolomite to optimize the melt properties.
  

• Cupola or electric melting furnace: Modern rock wool production lines often use large electric melting furnaces with temperatures up to 1500-1600 ℃, which reduce energy consumption by 30% compared to traditional cupolas and have cleaner emissions. Advanced furnaces are equipped with oxygen content monitoring and automatic adjustment systems to ensure consistent melt quality.

Fiber Forming System

• Four roll centrifuge: This is the core equipment of the production line, which uses high-speed centrifugal rollers with a speed of up to 7000rpm to spin molten rock into 4-7 μ m fine fibers. High end models adopt frequency conversion control, which can accurately adjust the fiber diameter and length according to product requirements.
  

• Pendulum cotton laying machine: By using a three-dimensional pendulum machine to evenly distribute fibers, a layered fiber structure is formed, which is the key to producing high-strength rock wool boards. The advanced cotton laying machine is equipped with a laser thickness gauge to monitor the uniformity of the cotton felt in real time, and the thickness deviation can be controlled within ± 1mm.

Curing and post-processing system

• Curing oven: a multi-layer curing oven with a length of up to 60 meters, using a hot air circulation system and a temperature control accuracy of ± 2 ℃ to ensure uniform curing of the adhesive. Some high-end production lines adopt microwave-assisted heating technology, which can shorten the curing time by more than 30%.
  

• High speed cutting saw: a CNC cutting system equipped with diamond cutting tools, with a cutting accuracy of ± 0.5mm, capable of processing various specifications and sizes. Advanced cutting lines are equipped with automatic dust removal devices to maintain a clean working environment.
  

• Surface treatment equipment: including automatic spray water repellent device, laminating machine, etc., to endow rock wool board with additional functions such as waterproofing and enhancing surface strength. The water absorption rate of rock wool board after hydrophobic treatment can be less than 1%, making it suitable for use in humid environments.

Modern high-end production lines adopt DCS distributed control systems to achieve full process automation from raw material input to finished product packaging.

System functions:

• Real time monitoring and recording of parameters: Over 500 sensors monitor parameters such as temperature, pressure, and speed, with a data retention period of up to 5 years, achieving full traceability.
  

• Intelligent diagnosis and warning: By analyzing equipment status through machine learning algorithms, potential faults can be alerted in advance, reducing unplanned downtime.
  

• Remote access and control: support engineers to conduct remote debugging and maintenance through the Internet, greatly improving service response speed.
