It has excellent physical and chemical properties such as fine particles, light weight, large specific surface area, strong volcanic ash activity and high refractoriness. If it is directly discharged into the air or captured and piled up in large quantities, it will cause air pollution or cause dust, posing a serious threat to human health and the surrounding environment. However, scientific research has found that microsilica fume has high economic value and can be widely used in concrete, cement, refractory materials and other fields. Therefore, it is necessary to collect the microsilica fume through a dust removal device.
