Process Flow Introduction

(1) Raw Material Batching

Natural rocks (such as basalt and diabase) and auxiliary materials are uniformly mixed according to the formula ratio.

(2) Melting

The materials are fed into the resistance furnace and melted at high temperatures to form molten lava.

(3) Fiber Blowing

The molten lava is drawn by high-speed airflow through a blowing device into fine, elongated fibers.

(4) Forming and Deposition

The fibers are uniformly deposited in the forming chamber to create a continuous rock wool blanket.

(5) Cutting and Shaping

The rock wool blanket or boards are cut to the required length using an automatic cutting machine.

(6) Bonding and Curing

Specialized adhesives and drying/curing equipment are used to achieve the required product strength.

(7) Inspection and Packaging

Finished products undergo quality inspection and are automatically packaged, ready for shipment.
