Main Equipment Components of the Rock Wool Production Line

The primary equipment configuration of a Rock wool Production Line comprises the following key components:

1. Melting Equipment:

Cupola Furnace: Used to melt rock (slag). Its furnace body incorporates a cooling water circulation system for safety assurance and features a hot air system preheated by the furnace's own temperature for efficient energy savings. The cupola furnace employs a single-row, multi-air-hole structure equipped with air volume control valves for convenient operation.

Gas-fired furnace (may be used in some production lines): Constructed with refractory materials, it melts raw materials by injecting natural gas into the tank via a spray gun.

2. Centrifugal forming equipment:

Four-roll centrifuge (or high-speed centrifuge): The primary equipment for producing rock wool and slag wool, it spins molten slag into fibrous strands to form inorganic wool. The four-roll centrifuge features reliable operation, high efficiency, excellent fiber quality, and easy maintenance.

3. Fiber Collection and Laying Equipment:

Fiber Collector: Utilizes vertical collection functionality to draw fibers ejected from the centrifugal spinner into the collector. Negative pressure air pulls the fibers onto a mesh belt to form a primary mat.

Pendulum Laying Machine: Used to lay the raw felt from the collector in a swinging motion, ensuring uniform thickness and enhancing product quality.

4. Boarding and Curing Equipment:

Curing Furnace (or Curing Oven): The equipment for product shaping. The laid-out raw felt is transported into the curing furnace, where hot air blown by a hot air blower cures and forms the felt into shape.

Cooling Cutting Machine: Used to cool and cut the cured rock wool boards. Typically, longitudinal cutting is performed first, followed by transverse cutting.

5. Other Auxiliary Equipment:

Automatic Batching Machine: Used for automated feeding and material proportioning.

Feeder: Operates in conjunction with cupola furnaces or gas-fired furnaces to convey raw materials into melting equipment.

Control System: Manages the coordinated operation of the entire rock wool production line.

Exhaust and Waste Treatment System: Processes exhaust gases and waste generated by equipment to minimize and prevent pollution.
