This article describes a way of reducing dust emissions of pollutions exhausted in the atmosphere in the manufacture of cement applying high effective wet dust cleaners with a combined scheme of separation of dust from the gas flow within systems cutting dusting aspiration. It was observed a short description of main technological processes, devices and related major sources of emissions and discharges of pollutants into the atmosphere in the cement manufacture in this article. It was described an industrial survey of a representative sample of aspiration systems and of cement’s enterprises using dust precipitators within those system. There concern the main results of the dispersed analysis of variance dimension’s particle of cement dust stemming and exhausting from the kilns in this article. There is describe a new wet dust cleaner cutting emissions of dust pollution aspiration schemes from kiln cement oven into atmosphere. It was fulfill experimental research to get evaluation of the leakage’s degree of dust particles mean as outlet exhaust’s coefficient for the elaborated wet dust cleaner. It was obtain treatment dependence of the outlet exhaust’s coefficient in the regression’s dependence as function of several parameters within research work field for this wet dust precipitator parameters. The tests showed that developed wet scrubbing dust collector reduced significantly cement dust emissions exhausting in the atmosphere and high degree of reliability one’s.

There presented paper presents the survey of industrial systems of aspiration and the results of analysis of variance of cement dust released from the equipment in this article. It was described the main technological processes, devices and related major sources of emissions and discharges of pollutants into the atmosphere in the cement factories in this paper. It was proposed a common generalized approach to determine the actual effective or hydraulic sized dust particles using by new experimental set up equipment to get high accuracy. It could be done using the results of analysis of variance (ANOVA) for sand’s dust and etc. bulk building construction materials. The development of new experimental set up equipment was ensured to decrease some negative influence of the old one. It was made a comparison changing cumulative distribution of the equivalent size of dust particles within aspiration schemes. I was fulfilled the comparison changing cumulative distribution of the equivalent size of dust particles after wet cleaners and inertial separation’s device (VZP) decreasing dust systems of aspiration schemes emissions exhausted in the atmosphere in the production of cement. The paper presents the ways to define cumulative distribution function depending of the equivalent size of dust particles of statistical processing the results of the analysis of variance by polynomial regression.
