RECOMMENDATIONS FOR THE SELECTION OF STANDARD SIZES OF THE BODY AND IMPACT ELEMENTS OF THE GRINDING AND MIXING ROTARY PULSATION COMPLEX

Abstract

In this article, the main recommendations aimed at the optimal choice of body sizes and impact elements of the grinding and mixing rotary pulsation complex, taking into account the power consumption, were analyzed and given. These recommendations were aimed at solving design problems related to determining the dependencies of the size of the housing with its main technological parameters, with the possibility of using data in the design of these complexes. Calculations of a number of basic standard sizes of the complex have been made taking into account the ratios of the diameter and width of the complex, the dimensions of the working elements, their body area, the number of slots based on the following input values, productivity, power consumption and a parameter characterizing the efficiency of the complex – alternating pressure in the channels of the rotor and stator. In the work, the power criteria calculated for the turbulent regime were determined. Graphical dependences of the total power costs of the complex on the rotational speed of the stator and rotor elements for a number of basic sizes of the complex are obtained. The housing of the complex was designed taking into account the accepted standard sizes. Taking into account the obtained values of the total power costs for each gap of the complex, the maximum radius of the rotor was determined. Taking into account the conditions of structural strength of the cylinder wall thickness of the complex, calculations were made for the diameters of the stator and rotor for a number of standard sizes of the complex. Based on these calculations, we selected the number of slots on the rotor and stator, their width and height
