Working area protection in foundry shops of machinery production
Introduction. The work objection is the investigation of the industrial safety of the foundry. The task to estimate a disperse composition of dust which determines the microclimate of the foundry working area is being solved. The dependence between the particle size and their motion speed under the...

| description | Introduction. The work objection is the investigation of the industrial safety of the foundry. The task to estimate a disperse composition of dust which determines the microclimate of the foundry working area is being solved. The dependence between the particle size and their motion speed under the gravitational or centrifugal forces is revealed. Materials and Methods. The granulometric composition analysis of a powder dust sample is carried out by the laser diffraction method implemented on the laser particle analyzer Fritsch NanoTec “ANALISETTE 22”. Research Results . The data analysis shows that all phases of the process determine the microclimate of the internal environment and, under the emission dispersion, the medium in the intercase zone. The impact degree depends on the dispersion and chemical composition of dust particles. The other harmful airborne substances deposited on dust particles make it more dangerous. For example, an increase in SiO2 content toughens the requirements for clean air in the working area. Therefore, it is necessary to take into account more rigorous values of maximum permissible concentrations (MPC). Discussion and Conclusions. The most dangerous areas of the foundry production in the eco-risk terms are identified; and proposals on the development of the dust-collecting system with water wash are made. The research results can be used in foundries of the machinery production. |
