Fully Automatic Rock Wool Board Production Line

The fully automatic rock wool board production line is an industrial system based on mineral raw materials such as basalt, which achieves continuous production of building insulation materials through intelligent equipment groups.

The fully automatic rock wool board production line integrates six core modules:

1. Raw material pretreatment system
   Adopting a dual path feeding design, equipped with 4-6 raw material silos, processing raw materials with a moisture content greater than 3% through a rotary kiln dryer, and ensuring smooth feeding with silos with cone angles of 58 ° -66 °.
   The error of the intelligent metering system is ≤ 0.5%, and the three-stage mixing process ensures the uniformity of the raw materials.

2. High temperature melting fiber making system
   The diameter of the 1800-1900mm blast furnace maintains a melting temperature of 1350-1600 ℃, and the thermal efficiency is improved by 40% with the use of layered combustion technology.
   The four roll centrifuge generates fibers with a diameter of 5-7 μ m, a fiber forming accuracy of ± 0.5mm, and a slag ball content of<5%.

3. 3D Cotton Fabric Forming System
   The vertical wire pendulum cotton machine achieves three-dimensional fiber arrangement (30% -40% fibers vertical) through a three-dimensional swinging device, increasing compressive strength by more than 50%.
   The patented gourd roller folding mechanism is combined with an inclined conveyor belt to form staggered pressing, with a density uniformity of 95%.

4. Composite processing system
   The dual drive roller extrusion process realizes the integration of mortar plastering, mesh cloth composite, and compression molding, supporting thickness adjustment from 2-150mm.
   The dust emission of wet cutting process is less than 15mg/m ³, and the daily output can reach 3000 ㎡ (8-hour working system).

5. Intelligent Control Center
   PLC+industrial cloud platform dual control system, real-time monitoring of melt bulk density (error ≤ 1.5%), dynamic adjustment of production line speed (response time 30 seconds).
   The AI visual quality inspection module automatically identifies product defects, reducing the scrap rate to below 0.3%.

6. Environmental Protection Treatment System
   The combination process of cyclone dust removal and activated carbon adsorption has a dust capture efficiency of 99.8%.
   The technology of crushing and blending scraps (particle size 3-5mm) achieves a waste utilization rate of 12%.
