sandwich panel line
The entire production workflow starts with standardized raw material pretreatment and intelligent batching, which lays a fundamental foundation for the stable quality of finished exterior wall rock wool boards. The main raw materials adopted are natural inorganic volcanic ores and auxiliary mineral materials with stable chemical properties, which are screened and processed through a series of physical pretreatment procedures. The raw material pretreatment module is equipped with automatic crushing, particle size screening, and impurity removal mechanisms, which uniformly process bulk raw materials into fine particles with consistent particle size distribution while eliminating mixed metal impurities and irregular sundries that may affect fiber forming quality. Different from traditional manual batching and rough mixing modes, the high-end rock wool sandwich panel production line adopts fully automated proportional batching and circulating mixing systems. The system can dynamically adjust the mixing ratio of different raw materials according to the performance orientation of exterior wall products, ensuring that the chemical composition of each batch of raw materials remains balanced and stable. This precise pretreatment process effectively avoids quality fluctuations caused by uneven raw material mixing in subsequent high-temperature processing, and fundamentally guarantees the uniformity, fire resistance, and weather resistance of finished rock wool boards used for exterior wall insulation.
High-temperature melting is one of the core processes that determine the fiber quality and core performance of exterior wall rock wool boards, and the high-end rock wool sandwich panel line is equipped with an optimized closed melting system different from traditional open melting equipment. The pretreated mixed raw materials are continuously and quantitatively sent to the high-temperature melting furnace through a fully automatic sealed feeding device, which avoids heat loss and external dust pollution during the feeding process. The melting furnace adopts an intelligent temperature control and atmosphere adjustment system, which can maintain a stable high-temperature melting environment and realize real-time monitoring and fine adjustment of the melting state of internal raw materials. The system supports dynamic adjustment of melting parameters according to raw material characteristics and product performance requirements, ensuring that all raw materials are completely melted into uniform and fine molten slurry without local overheating or insufficient melting. Meanwhile, the supporting waste heat recovery and circulation utilization structure inside the melting system effectively improves overall thermal efficiency, reduces ineffective energy consumption in the production process, and realizes more environmentally friendly and energy-saving production operation while ensuring melting quality. The stable and uniform molten slurry formed by high-quality melting provides excellent raw material conditions for subsequent ultra-fine fiber forming, directly determining the fineness, toughness, and structural uniformity of rock wool fibers.
Fiber forming is the key link to shape the thermal insulation and structural performance of rock wool boards, and the high-end rockwool sandwich panel production line adopts a high-efficiency four-roll centrifugal fiber forming system as the core equipment, which is far superior to traditional single-roll or double-roll centrifugal structures in fiber forming accuracy and stability. The high-speed centrifugal rollers of the system operate at a stable high rotating speed, uniformly throwing the high-temperature molten slurry into countless ultra-fine inorganic fibers through high-speed centrifugal force. The frequency conversion speed regulation technology adopted by the equipment can precisely adjust the rotating speed and operating state of the centrifugal rollers in real time, flexibly controlling the diameter and length distribution of rock wool fibers to adapt to different exterior wall application scenarios. The fibers formed by this process have uniform thickness, complete fiber structure, and excellent tensile toughness, avoiding the defects of thick fiber diameter, uneven distribution, and many broken fibers easily produced by traditional fiber forming equipment. During the fiber forming process, the system is also equipped with a quantitative atomizing spraying mechanism, which evenly sprays environmentally friendly adhesive and auxiliary dust-proof materials on the surface of scattered fibers. The uniform attachment of auxiliary materials enables the loose fibers to obtain preliminary bonding force, laying a good foundation for subsequent uniform cotton laying and integral forming, and effectively improving the overall compactness and structural stability of finished rock wool boards.
The cotton collecting and pendulum cotton laying process determines the flatness, thickness uniformity, and three-dimensional structural stability of rock wool board blanks, and the high-end rock wool sandwich panel machine adopts an intelligent reciprocating pendulum cotton laying and layered paving technology exclusive for exterior wall boards. Different from the single flat laying mode of traditional production lines, this advanced process realizes staggered layered paving of fibers in vertical and horizontal directions through the cooperative operation of a high-precision cotton collector and a reciprocating pendulum mechanism. The fibers form a dense three-dimensional interwoven structure inside the board blank, and a certain proportion of vertical fiber arrangement is formed inside the product through mechanical folding and pressing optimization. This unique fiber laying structure significantly improves the compressive resistance, shear resistance, and structural firmness of exterior wall rock wool boards, effectively solving the problem of insufficient structural strength and easy delamination of traditional flat-laid rock wool products under long-term external pressure and weather erosion. The cotton laying system supports continuous and stable feeding and adjustable paving thickness, and can produce board blanks with uniform thickness and flat surface in a wide range of specifications. The fully closed cotton laying environment avoids fiber scattering and external impurity mixing, ensuring the internal purity and structural uniformity of the board blank, and further optimizing the overall quality stability of the product.
Curing and integral forming are critical processes for finalizing the structural performance and dimensional stability of exterior wall rock wool boards. The high-end rock wool board production line is equipped with a segmented constant-temperature curing furnace with precise temperature and air volume control functions, which adopts a multi-stage gradient heating and uniform air supply mode. The loose fiber board blanks after cotton laying and pre-pressing are continuously sent into the curing furnace, and under the action of constant-temperature hot air circulation, the adhesive on the fiber surface is fully cured and cross-linked, making the scattered fibers closely bonded into an integral plate structure. The segmented temperature control design enables the board blank to complete gradual shaping, internal stress elimination, and structural stabilization in different temperature intervals, avoiding product deformation, warping, or internal loose structure caused by excessive instantaneous temperature difference. The curing furnace is equipped with an internal circulating air purification and heat preservation structure, which not only ensures uniform temperature distribution in the curing chamber and consistent curing effect of each part of the board blank, but also improves heat energy utilization efficiency and reduces production energy consumption. After continuous curing, the rock wool board blank forms a dense, stable, and uniform integral structure, with significantly improved internal bonding strength, overall toughness, and structural durability, fully meeting the long-term service stability requirements of building exterior walls in complex outdoor environments.
The post-processing system of the high-end rockwool board production line realizes precise shaping and standardized finishing of finished products through automated continuous cutting, trimming, and cooling processes. The cured rock wool board semi-finished products are continuously and stably conveyed to the precision cutting unit, which adopts multi-dimensional synchronous cutting technology to perform fixed-size cutting, edge trimming, and surface finishing according to the set product specifications. The high-precision transmission and cutting positioning system ensures that the dimensional error of finished products is controlled within an extremely small range, and the cut surface is flat and neat without burrs, cracks, or edge collapse defects, which improves the assembly accuracy and aesthetic effect of exterior wall construction. After cutting and shaping, the finished products enter the automatic cooling and shaping area for slow cooling treatment, which effectively eliminates the internal residual stress generated during high-temperature curing and processing, ensuring that the finished rock wool boards will not undergo dimensional deformation or structural changes during subsequent storage, transportation, and construction. Meanwhile, the system is equipped with an automatic waste recycling mechanism, which collects and reprocesses the edge materials and leftover materials generated in the cutting process, realizing full recycling of production materials, reducing material waste, and improving the overall resource utilization rate of the production line.

The whole line adopts integrated electromechanical linkage control, realizing automatic closed-loop operation from raw material feeding, pretreatment, melting, fiber forming, cotton laying, curing to post-processing and finished product output. The centralized intelligent control platform can monitor the operating parameters of each equipment module, production status, and product quality indicators in real time, and realize automatic early warning and adaptive adjustment of abnormal parameters during production. This highly automated operation mode greatly reduces manual intervention links, avoids product quality fluctuations and unstable production efficiency caused by human operation errors, and realizes long-term stable continuous production. In addition, the whole production line adopts a closed and dust-reducing structural design, which effectively controls fiber dust and material overflow during the production process, improves the cleanliness of the production environment, and realizes green and low-carbon production while ensuring production efficiency and product quality.
