Грохоты используют для механического просеивания сыпучих веществ, просушивания материала. Применяются в горнодобывающей, металлургической промышленности, строительной и сельскохозяйственной сферах.
Разделение материала происходит под воздействием вибрации и силы тяжести. Грохота могут разделить сыпучие вещества разной дисперсности в зависимости от величины. Для этого используются сита с разной величиной отверстий, установленные под наклоном на вибростол.
