Basalt Continuous Fiber technology & equipment - Production techniques

Production techniques CBF

Basalt rocks are crushed in 5~20 mm fraction→

??????????????? ?????

Crushed raw material transported into the furnace melting (2) by loader (1) → Inside the furnace basalt is melted at 1400 - 1600 0? → Basalt passes through a platinum alloy set - holes of bushing (3) → Continues filament formation with diameter 9~15 microns (4) is lubricated through the lubricator (5) and reeling up by the winding machine (6) on bobbins (7) → Rewinding of primary string by machine (8) from bobbins (7) on roving spool (9)

ADVANTAGED OF CBF TECHNOLOGIES

1. Only one component – basalt, which is an enviromently safe natural material – is used for CBF production;

2. Cost of basalt raw material is very low; the share of raw material’s cost in the final cost of production is less than 5%;

3. CBF production technology consists of only one phase – melting. There is no need for primary enrichment, fusion and homogenization, as all of those were made for free by nature;

4. To make CBF basalt should be heated up only one time;

5. Further processing of CBF into materials does not require energy; it’s made with application of “cold technologies".
