Rinsing is a method of refining aggregates that enables dust impurities to be removed, i.e., grains of up to 0.05 mm in size. In aggregate production plants, they are used to remove light organic impurities found in aggregates. On the other hand, sand used for mortars or concrete must be rinsed naturally or in aggregate processing installations.
