During the production of basalt aggregates, we ensure product quality and pay attention to safety measures to minimize accidents during the production process.

The reasons why basalt aggregates are widely favored
As consumer demand for personalized products grows, basalt aggregates have seen rapid development, and their use in stone construction and related services has gradually gained consumer recognition. In recent years, customized basalt products that meet personalized design needs have remained the mainstream in the basalt market. Below, the editor introduces why basalt aggregates are so popular.

Basalt rock fiber is used in the upper layer.
The acidity coefficient Mk for Wuwu Rockstone Fiber is Mk = (WSiO2 + WAl2O3 / (WCaO + WMgO)) [16]. The lower the Mk, the better the chemical durability and the higher the operating temperature. The pH value calculation formula for CBF is pH = -0.0602WSiO2 - 0.12WAl2O3 + 0.232WCaO + 0.120WMgO + 0.144WFe2O3 + 0.217WNa2O. The higher the pH value, the more basic oxides there are, and the poorer the water resistance. Generally speaking, <4 is stable, <5 is stable, and <6 is moderately stable.
Fiber calculation is 5.48, with a pH value of 1.7. Its operating temperature range is -269 to 650°C, while glass fiber is 60 to 450°C. At a high temperature of 900°C, the CBF experiences a 12% quality loss [17]. Therefore, CBF is used as a high-temperature filtration material for air purification and sterilization in the antibiotic production process.
In summary, as the production bottleneck of continuous basalt aggregate fiber technology is continually being broken through and unit costs are reduced due to mass production, basalt aggregate fiber, as a new material, will continue to develop.

The process of making sand from basalt aggregates has always been a persistent problem in the hydropower industry, particularly ensuring the compliance of the crushed sand and stone powder content. The recycling process for the stone powder is indispensable.
