Abstract:

Purpose. A study of the change in the magnitude of productivity of a shock-centrifugal 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 single-chamber and two-chamber 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 single-chamber disintegrator in the new two-chamber design, the yield of the fine fraction of the rock mass is increased by 1.3‒1.7 times, and the productivity of the disintegrator 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 two-chamber impact-centrifugal 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 two-chamber impact-centrifugal 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 two-chamber impact-centrifugal disintegrator for use in industrial conditions.
