Structural composition
1. Machine Frame and Drive System: Heavy-duty machine frame equipped with four independent overclocking motors, each driving one of the parallel centrifugal rollers for high-speed rotation in pairs (speeds up to9,000,000 revolutions per minute), fitted with precision transmission and cooling sealing devices.
2. Centrifugal Roller Assembly: The rolling surfaces/edges are designed with special flow channels or nozzles, usually equipped with internal cooling water jackets to prevent high-temperature deformation. The rollers are made of high-temperature-resistant and wear-resistant materials, with a service life far exceeding 72 hours and a conventional service life of 120 hours. Experimental costs are low.
3. Annular and Airflow System: An annular air duct surrounding the rollers, made of wear-resistant stainless steel, which supplies high-speed secondary air to assist in the stretching and cooling of the melt and blow the fibers toward the collection chamber.
Working principle
Feeding and Film Formation: High-temperature molten rock (approximately 1400–1500°C) is uniformly distributed via a launder to the first-stage low-speed centrifugal roller (2500–3500 revolutions per minute), forming a thin molten film on the roller surface.
01
Multi-stage fiberization: The melt is flung toward the roll edges under centrifugal force, with part of it directly forming fibers; the remaining melt is transferred to the next stage of high-speed rolls (up to 7000 revolutions per minute), where centrifugal spinning and stretching refinement are repeated to gradually improve fiber fineness and uniformity step by step.
02
Sizing and Cooling: As the fibers are ejected, the atomized binder evenly coats the fibers; the high-speed airflow around rapidly cools the melt to prevent fiber coarsening, while guiding the direction of the fibers.
03
Cotton collection and forming: Fibers are blown by airflow onto the mesh belt of the cotton collector, interweaving into a fluffy cotton felt before entering the subsequent curing process.

Product Advantages：
1. Each machine has a large production capacity, capable of reaching 5-8 tons per hour. It has low power consumption. The maximum power of the single roller head is 30Kw, and the small roller head can be designed to be 22Kw. The equipment has a low failure rate. It is assembled with new type structural components and precision processing parts, and manufactured with advanced techniques. The high-speed and high-precision bearings and other wear-prone parts have a long service life, which is much higher than the performance of equipment from other companies.
2. The forming air duct is flexible and adjustable, customizable. The wind force requirement is not high, and the adjustment is simple.
3. The cost of using adhesive materials is low, the dispersion is good, the distribution is uniform, and the product strength is high.
