The purpose of the study was to research the feasibility and determination of the expediency of cleaning waxy raw materials by releasing from pol-luting components prior to its dewatering in various types of wax-ups. The main pollutant of wax raw materials significantly reducing the quality and yield of commodity wax during ditching is bee-bread. The technique and results of the experiment for deter-mining cleaning efficiency of crushed wax raw ma-terial with intensive mechanical mixing in water are described in the study. The influence of two factors, the intensity of mixing and mixing time on relative change in dry weight of the feedstock, caused by the removal of water-soluble impurities, including bee-bread is evaluated. An adequate empirical de-pendence is established, which determines the in-fluence of these factors on optimization criterion. The optimization of obtained model is carried out, the values of the factors under which it is expedient to carry out wet cleaning of crushed wax raw mate-rial by means of intensive mechanical mixing are determined. In particular it is found out that the optimi-zation criterion on relative change in dry weight tends to the maximum at mixing intensity of 15 kW/m3 for 9-10 minutes, after which most of contained bee-bread is completely broken up to individual pollen grains and passes through the cells of the filter net, on which raw material remains purified waxy mate-rial. The results of the study make it possible to determine the main parameters of wax raw material purification regime using mixing devices of various dimensions.
