“…Particles are typically classified into solid particles (e.g., powders), liquid particles (e.g., droplets and oil beads), and gas particles (e.g., bubbles in liquids) 1 . Numerous methods, including the airflow acceleration method 2 , mechanical acceleration method 3 , electromagnetic acceleration method 4 , ultrasonic acceleration method 5 , and thermal expansion acceleration method 6 have been developed to accelerate particles to a certain speed, enabling various tasks such as separation, throwing, and impact crushing. Notably, that these methods are widely used in diverse fields such as intelligent manufacturing, chemical industry, weaponry, and mining 7 – 16 .…”

In this study, the impact of flow channel structures on the acceleration of metal particles in a vacuum environment is explored, with the aim of enhancinge the acceleration quality in the centrifugal impact molding of metal powders. To assess this phenomenon, three evaluation indices are introduced: the average speed of particles thrown $${V}_{p}$$ V p , the average speed of the particles $${V}_{all}$$ V all , and the particle velocity distribution Vf (t). Additionally, the effects of six distinct runner structures on the centrifugal acceleration of the particles are analyzed in this research. The findings indicate that the arc-shaped flow channel structure not only ensures a more consistent acceleration process but also results in a higher ejection speed, leading to an improved acceleration effect. The unique contribution of this study is the examination of the relationship between flow channel designs and particle accelerations in a vacuum.

“…These graphs testify to the fact that in case of using a diagram of two-stage crushing and correct adjustment of crushing units under consideration it is possible to attain a change in the balance of fractions of coarse filling aggregates within rather wide limits. In this case a conical crusher is used as a secondary crushing unit (Shadrunova et al, 2015).…”

The paper considers the problem of the organization of the technological line for the production of building aggregates with a given particle size distribution. The advantage of two-stage crushing schemes is shown, which makes it possible to ensure a change in the ratio of large aggregate fractions within fairly wide limits. The experience of using centrifugal-impact crushers for the operation of the production of CJSC Ural-Omega at the final stage of crushing is summarized. It was demonstrated that the use of two centrifugal impact crushers at the final stage of crushing allows to obtain mixtures of significantly different types. A method for selecting the option of organizing the process line and crushing parameters is proposed.
