Rock Wool Production Line

The rock wool production line is a highly automated industrial production system, mainly used to process raw materials such as basalt and slag into high-quality building insulation materials.

The core process of rock wool production line mainly includes high-temperature melting, centrifugal fiber forming, cotton felt collection, solidification molding and other links. The specific process is as follows:

• High temperature melting: Put raw materials such as basalt into a closed furnace for full melting, change the physical structure of natural ores, and lay the structural foundation for making rock wool boards.
  

• Centrifugal fibrillation: Using high-speed centrifugal machines to process the melted raw materials, gradually forming filamentous substances. After all the spun fibers are bonded together, inorganic cotton is obtained.
  

• Cotton collection felt: Adding water increasing agents and binders to inorganic cotton to prevent water infiltration and provide high strength and hardness. Then, using a cotton collection machine and a pendulum cotton machine, the inorganic cotton is sorted into a felt shape.
  

• Curing molding: The collected rock wool felt is sent to a curing furnace for high-temperature drying treatment, which makes the shape of the rock wool more fixed, and the density and hardness continue to increase, ultimately obtaining rock wool board.

The main equipment of the rock wool production line includes a fully automatic ore metering and proportioning feeding system, a blast furnace, a high-speed centrifuge, a cotton collector, a pendulum cotton machine, a folding pre press machine, a solidification forming furnace, size cutting equipment, packaging equipment, etc. These devices work together to complete the entire production process from raw material feeding to finished product packaging.

FEATURES

• Vertical wire structure technology: By using a vertical wire pendulum cotton machine to swing back and forth above the inclined conveying mechanism, combined with a gourd roller folding mechanism to form an up and down staggered compression, 30% to 40% of rock wool fibers are arranged vertically. This technology can significantly improve the compressive strength of the product.
  

• Intelligent control technology: Integrating pressure sensors and visual monitoring devices to build a closed-loop control system, achieving a melt weight detection error of ≤ 1.5%, shortening the response time of production line speed adjustment to 30 seconds, effectively solving the lag problem of traditional power detection methods.
  

• Energy saving design: Adopting a closed-loop heat recovery system to achieve energy recycling and reduce energy consumption.
  

• Environmental protection measures: The exhaust gas treatment system adopts a combination of cyclone dust removal and activated carbon adsorption process, and the dust emission concentration is controlled at a low level. At the same time, the waste recycling device can crush the cutting scraps and reuse them, reducing resource waste.

The rock wool and its products produced by the rock wool production line have the advantages of light bulk density, low thermal conductivity, non flammability and non corrosion, heat resistance and insulation, wide temperature range, and long service life. They are widely used in industries such as construction, metallurgy, machinery, building materials, petroleum and chemical. At the same time, rock wool products also have excellent sound-absorbing properties and can be used to make sound-absorbing materials.
