Description
There has been developed the design of the single disc centrifugal apparatus with the feed of the granular material along the blades. The scattering disc consists of blades, on the top shelf there is a flat disc with air intake windows (deflector). The purpose of the deflector is to eliminate the reflection of particles at the moment of contact with the blade and create a passing air flow to increase the range of flight of the particles. The analysis of the constructive scheme of the scattering disk showed that the amount of air coming inside the scattering disk is affected by the width of the window and the tilt angle of the deflector body. There was determined the dependence of the window width from the angle of the deflector body and height. Based on the analysis of the design there have been determined the limits of setting the window width and the tilt angle of the deflector body. The angle of the deflector body changes in the rate of 90 to 320 . Increasing the tilt angle of the deflector body leads to a proportional reduction of the window width. There have been set the intervals of variation of factors. There have been chosen the symmetrical composite plan of the second order and have been made a matrix of the experimental design. As a function of the response factor there have been taken a relative accuracy coefficient. The implementation of the experiment allowed us to determine the value of the regression coefficients. The adequacy of the regression equation to the equation obtained was performed by the Fisher test. It was determined that the equation adequately describes the technological process. For the analysis of this equation it was turned to the canonical form by moving the origin to a new point and turning at a certain angle of 14,950. The analysis of the canonical equations allowed the authors to determine the optimal values of the studied factors. The window width of the deflector is 22 - 25 mm, the angle of the body of the deflector is 8 - 120
