СВЯЗЬ ВЕРОЯТНОСТИ ПРОХОЖДЕНИЯ ЧАСТИЦ ГОРНЫХ ПОРОД СКВОЗЬ РЕШЕТКУ ГРОХОТА С ЭФФЕКТИВНОСТЬЮ ГРОХОЧЕНИЯ

The article examines the effectiveness of the theoretical defi nition of vibrating screens. It is shown that the theoretical effi ciency of screening depends on the number of particles of rock beats the bars on screen and can be defi ned as the probability of the passage of particles through this grid. Proposed dependence adequately refl ects the technological process of mineral processing. The interrelation between constructive and regime parameters screen with the number of possible attacks against the bars screen. To study the effect of input parameters while observing the elastic and frictional characteristics of rocks composed mathematical model incorporating the equation of the free fl ight of the particles and their impact on an inclined plane. It is proved that the defi nition of the required value number of beats particles is reduced to the determination of kinematic parameters of motion of the particles on the surface of screen and limited by the length of the working surface.
