The content of free silicon dioxide in dust, is an important basis for the design and inspection of the working environment. Produce fine dust containing free silica in industrial processes (particle size 5μm or less) has great harm to the operator, so the design dust removal device, you must obtain the content of free silica dust. Measured by the analysis and research on information that the crushing and screening (packaging) and when the transport of metal ores, free silica content in the dust is about 63% - 83% of free silica content in the ore.
