Приведен комплексный анализ процессов вибрационной сегрегации в условиях сухого разделения углеродсодержащих пород шунгитового типа. Основное внимание уделено изучению влияния времени воздействия вибрации на слой материала, его толщины и структуры — на эффективность грохочения и распределение фракций по крупности. Для оценки перераспределения материала под воздействием различных факторов предложен и обоснован показатель, характеризующий степень сегрегированности слоя материала. Результаты исследования на грохоте подтвердили возможность интенсификации процесса за счет оптимизации структуры подаваемого слоя. Они показали, что в зависимости от степени сегрегации слоя извлечение расчетного класса в подрешетный продукт увеличивается в диапазоне от 2,59 до 7,2 %. В результате предложен поправочный коэффициент в расчетные модели грохота, позволяющий учесть возможность повышения эффективности грохочения при предварительном структурировании подачи питания аппарата.
