Abstract
Способ для сбора мелочи утяжелителя включает измельчение утяжелителя в мельнице на множество частиц, классификацию частиц по размеру для извлечения частиц, имеющих размер частиц меньше, чем допустимый максимальный диаметр, повторную классификацию частиц по размеру для извлечения частиц, имеющих размер частиц меньше, чем допустимый минимальный диаметр, сбор частиц, имеющих размер частиц между стандартными допустимыми минимальным и максимальным размерами, и сбор частиц, имеющих размер частиц меньше, чем допустимый минимальный диаметр. Система для сбора мелочи утяжелителя содержит мельницу для уменьшения размера частиц утяжелителя, первый классификатор для извлечения частиц, имеющих размер частиц меньше, чем допустимый максимальный диаметр, второй классификатор для извлечения частиц, имеющих размер частиц меньше, чем допустимый минимальный диаметр, место сбора мелких частиц и место сбора крупных частиц.
