STAND FOR EXTRACTION OF LONG-TERM APPLICATIONS FROM GRANULAR MIXTURES
The need to reduce the length of the bench cellular surface in order to increase the angle of inclination of the bottom of the output tray to the horizon with the allocation of long impurities that have an increased asymmetry of geometric dimensions and limited dynamics of the motion along inclined planes when they are ejected into the output tray is justified. It has been established that for the initial position of the output tray with the angle of rise of the upper edge of the front wall of 300, the slope to the horizon of the axial line of the bottom is 43,50, and in the lower position of the edge with an angle of 150 degrees, the slope of the critical trajectories of the separated long grain grain particles to the horizon is 310. Reducing the initial position of the output tray by 50 provides an angle of inclination of the axial line of its bottom at 41,90, but the angle of inclination of the critical trajectory of particles to the horizon increases to 32,340. It is justified that further lowering of the initial position of the upper edge of the front wall of the output tray disrupts the objective assessment of the dynamics of the technological process, since the upper edge falls into the zone of circulation of the layers of the grain segment. The range of loading of the mesh cylinder of the stand, which is necessary for reproducing the consumption characteristics of a standard cylinder within the range of 23... 100% of the rated value, is determined by calculation. With the use of the method developed by us to identify the consumption characteristics of the trihedral unit, the multiplicity of the summation of the individual regularities of bench implementations of the dynamics of the technological process is established by the results of bench studies. The effectiveness of solutions to eliminate the effect of wall effects on the dynamics of the process in bench research due to the end clearance between the back wall of the output tray and the drive disk and the use of a cylindrical shell on the locking ring was confirmed.
