What equipment is included in the rock wool production line

1. Raw material processing and feeding system

Responsible for the measurement, proportioning, and transportation of raw materials. The core equipment includes automatic batching machines, control cabinets, and feeding machines. Modern production lines use electronic metering for fully automatic feeding, which can accurately control the proportion of raw materials and ensure product stability.

2. Melting system

Melting raw materials such as basalt and dolomite into lava at high temperatures, the core equipment includes a blast furnace/electric furnace, furnace frame, melting furnace level control system, dust collector, and exhaust gas treatment device. The current industry upgrade direction is to replace traditional blast furnaces with electric furnaces, which can reduce energy consumption and pollutant emissions.

3. Fiber making system

Processing high-temperature lava into inorganic rock wool fibers is the core process that determines the quality of rock wool. The core equipment includes high-speed centrifuges (mainly four roll centrifuges, with fiber forming accuracy up to ± 0.5mm), fans, blowing air boxes, and slag removal machines. The uniformity of fibers formed by centrifugation directly affects the insulation performance of the finished product.

4. Glue application system

Spraying binders and water enhancers in the fibers gives rock wool strength and waterproofness. The core equipment includes metering pumps, spray heads, and control cabinets. Some high-end production lines are equipped with laser lava tracking systems, which can accurately control the amount of glue applied.

5. Cotton collection and fabric cotton system

The core equipment for collecting and shaping fibers and adjusting density includes drum cotton collectors, pendulum cotton looms, cotton induced draft fans, and cotton dust collectors. The pendulum cotton loom can achieve three-dimensional cotton distribution with a uniformity greater than 95%, ensuring consistent density of the finished product.

6. Molding and curing system

The core equipment for curing the adhesive to achieve the specified strength and hardness of the rock wool includes a pendulum cotton machine, a forming machine, a folding pre press machine, and a curing furnace. The temperature control accuracy can reach ± 2 ℃, which is crucial for the performance of the final product.

7. Cutting and shaping system

Cutting the solidified rock wool into standard specifications, the core equipment includes a longitudinal cutting machine, a transverse cutting machine (cross cutting machine), a cooling conveyor, a trimming machine, and a dust removal system. Some high-end equipment is equipped with high-precision length measuring devices and patented vacuum suction structures, with high cutting accuracy and minimal dust leakage.

8. Auxiliary supporting system

The fully automated production line includes a waste edge recycling system (crusher, scrap edge recycling fan, which can recycle the produced scraps and reduce raw material loss), a solidification furnace hot air system, an explosion-proof system (natural gas detection, explosion-proof fan), a packaging palletizing system (automatic palletizing machine, packaging machine), a central control system, and a PLC central control system to achieve full automation operation.
