the reSultS of exPeriMentAl StudieS of influenCe of VAriABle PArAMeterS on the PerforMAnCe indiCAtorS of ShoCk-CentrifuGAl diSinteGrAtorPurpose.A study of the change in the magnitude of productivity of a shockcentrifugal disintegrator and the power output of its drive, with variations in the rotor speed with impactors in the chamber, the size and type of the initial grinded rock mass, and comparison of the technological performance of a singlechamber and twochamber disintegrator.Methodology.Laboratory research on bench equipment with subsequent processing of the experimental results obtained by computer programming.findings.It is established that in comparison with the singlechamber disintegrator in the new twochamber de sign, the yield of the fine fraction of the rock mass is increased by 1.3-1.7 times, and the productivity of the disinte grator and the reduction of grinding time of the rock mass are fixed.originality.For the first time, the character of the dependence of productivity of a twochamber impactcentrifu gal disintegrator and the power of its drive on its rotations and characteristics of the crushed rock mass is determined, and the distribution of classes of the crushed rock mass after grinding is established.Practical value.The new design of the twochamber impactcentrifugal disintegrator is efficient and promising because it divides the flow of rock mass into two chambers and thereby reduces the load on the rotor shaft, which increases its working time and the productivity of the disintegrator, and also reduces the grinding time of the rock mass.This allows recommending a new construction of a twochamber impactcentrifugal disintegrator for use in industrial conditions.
