Design of the forming device with a vertical blow head for the production of synthetic fibers intended for filter process in the mining industry

different liquid substances. These mining processes need to be drained and, given the increased demand for organic processes, water has to
be separated from undesirable substances. One of the undesirable substances in the mining process is the oil from the hydraulics mining
machines that can contaminate this water. Various technologies and devices are used for filtration, for example, separators. These
separators contain filters that can also be made from synthetic fibrous materials. The synthetic fibrous materials for the filters are
manufactured by different technologies. The article presents the technology of producing synthetic fiber material by vertical blowing method
from thermoplastic raw materials. Namely, the characteristics of the fiber forming device (blow head with an annular converging nozzle) are
defined and designed. As a result of the blow head investigation, the values of air rarefaction and air flow in the central hole of the annular
nozzle were determined from the process parameters. Also, the result of the blow head study is the determination of the design
characteristics, the influence assessment of various design and operational factors on its work, allowing the elementary fibers to be drawn
out in a single technological cycle to form a fibrous material for the filters.
