Determination of dust disperse composition in energy-efficient aspiration systems for building materials production

In various industries, primarily, the production of building materials, technological processes include multiple transfer operations, during which a large amount of dust is released. The resulting dust causes air pollution and various diseases of workers. To prevent this, different dust removing systems are used. One of them is the aspiration system, which includes air purification devices. For the operation of these systems, it is necessary to obtain the data on the disperse composition of dust and its concentration. Since aspiration systems consume a lot of energy, various improvements are used. Here, basing upon the processed experimental data, the authors proposed a method to determine the main parameters of the dust flow, formed in the bulk materials transfer units of energy-efficient aspiration systems.
