What is the difference between effective density, true density and apparent density?
True Density: The theoretical density of powder materials. The volume used in the calculation is the volume of particles. It excludes open and closed pores. Effective density (floating density): The density value that can be effectively utilized by powder materials. The volume used is the volume of particles. It includes closed pores. But, it does […]
Selection principle of bag filter filtration speed
Selecting the filter speed of bag dust collector is key. It should be based on the type of smoke or dust. It should consider where it will be used. It should also consider dust size, thickness, and gas temperature. Also, it should consider moisture, dust levels, and filter materials. Select a low value when the […]
