Fireproof Rock Wool Board Production Line

The fireproof rock wool board production line has achieved high-performance and high safety industrial production through precision equipment linkage and process optimization, becoming one of the core materials for modern building energy conservation and fire safety.

sandwich panel line

Fireproof rock wool board is an inorganic fireproof insulation material mainly made of basalt, which is melted and fiberized at high temperature. It is widely used in the fields of building exterior walls, fireproof isolation belts, industrial equipment insulation, etc. The fireproof rock wool sandwich panel production line operates through highly automated equipment to achieve the full process of production from raw material processing to finished product packaging.

Core Equipment

• Raw material melting system
  Cupola: Melting raw materials such as basalt and slag at high temperatures to form liquid magma.
  Centrifuge: The lava is spun into fibers by a high-speed rotating four roll centrifuge, while a binder (such as phenolic resin) is sprayed to enhance the fiber bonding strength.

• Fiber Forming System
  Cotton collector: uses negative pressure to evenly collect fibers onto the mesh belt, forming loose raw cotton felt.
  Pendulum cotton machine: By swinging the pendulum, the fibers are distributed in three dimensions, improving the uniformity and density of the cotton felt.

• Curing and Pressing System
  Curing oven: High temperature curing cotton felt to fully crosslink the adhesive and form a stable structure.
  Cotton compactor: Multiple layers of rollers are used to compact the cotton felt, adjust the density, and meet the requirements of different fire protection levels.

• Cutting and post-processing system
  Vertical/Horizontal Cutting Machine: Accurately cut into standard sizes.
  Edge cutting machine: Trim the edges to ensure the flatness of the board.
  Waste recycling system: Crushing waste materials for reuse and reducing losses.

• Composite process (optional)
  Sandwich panel line: producing fireproof rock wool sandwich panels through glue coating and pressing (such as "steel plate rock wool steel plate" sandwich structure), suitable for fast installation in industrial buildings.

Production Process Flow

• Raw material pretreatment: Basalt and auxiliary materials are mixed in proportion and fed through an electronic metering system.
  Melting into fibers: After high-temperature melting, centrifuge into fibers and spray glue to shape.
  Cotton curing: pendulum cotton → pre pressing → high temperature curing → cooling.
  Cutting packaging: automatic cutting → stacking → film covered moisture-proof packaging.

Technical Features

• Efficient and energy-saving: Adopting a waste heat recovery system to reduce energy consumption.
  Automation control: The PLC central control system realizes full process monitoring to ensure quality stability.
  Environmental friendliness: The exhaust gas is treated with dust removal and the waste is recycled, meeting green production standards.
  Product diversity: By adjusting process parameters, different densities, thicknesses, and composite boards can be produced.

Application Fields

• Building fire prevention: external wall insulation, fire isolation tape, roof insulation.
  Industrial field: Fire and insulation of pipelines and storage tanks.
  Special requirements: customized products with high hydrophobicity and high compressive strength.
