Core Equipment Knowledge Points

1. Melting System
Mainstream: Cupola furnace, Electric arc furnace, Tank kilnTemperature: 1400～1500℃
Key Control: Stability of melt temperature, viscosity, and flow rate directly determines fiber quality.
2 Fiber Core: Rock Wool Spinning Centrifuge
Mainstream Model: Four-roller centrifuge (highest efficiency, finest fiber)
Principle:rifugal force high-speed airflow stretching → Pulling the melt into fiber
Fiber Diameter: 4～7μm (standard for high-quality wool)
Key: Matching roller speed, water cooling, dynamic balance, air ring air velocity
3. Spray Adhesive System
Adhesive: Phenolic resin the main component, now developing towards non-formaldehyde environmental protection adhesives
Function: To make fibers stick together and have strength after curing
Control Points:iform atomization, stable amount of adhesive, no dripping, no clogging of the gun
4. Cotton Collection & Pendulum Weaving
Cotton Collector Negative pressure suction of cotton, forming a uniform cotton layer
Pendulum: Left and right pendulum laying felt, so that fibers cross each other vertically and horizontally, strength and uniformity
Decision: Rock wool density, thickness uniformity
5. Curing Oven (Decides product strength)
Structure: Tunnel-type continuousuring
Temperature: 180～240℃ Zone temperature control
6. Cutting System
Longitudinal Cutting: Circular knife, fixed width
Transverse Cutting: Flying / synchronous cutting, fixed length
Common Accessories: Scraps crushing and recycling (recycling, reducing cost)
7. Waste Gas and Environmental Protection ( very critical)
Dust Removal: Bag filter dust removal
Waste Gas: VOCs treatment, incineration / catalytic oxidation
Environmental protection does meet the standard → Full line shutdown
8. Key Process Indicators (strong correlation between machinery and process)
Fiber Formation Rate: The higher, the better, generally≥85%～90%
Inclusion of Scoria: The lower, the better, high-quality products ≤3%
Fiber Diameter: 47μm (the finer the insulation, the higher the strength)
Density Tolerance: Within ±5kg/m³
Moisture content, combustion performance, thermal conductivity are all determined by the stability of the equipment

A single machine boasts high production capacity, reaching 5 to 8 tons per hour, with low power consumption. The maximum power of a single roller head is 30 kW, while small roller heads can be designed as 22 kW. The equipment features a low failure rate. It is assembled with newly structured precision-machined parts and manufactured using advanced processes. Vulnerable components such as high-speed and high-precision bearings have a long service life, and the overall performance is far superior to that of similar equipment from other manufacturers.
