FIELD: process engineering.
SUBSTANCE: invention relates to grading of mineral components and can be used in construction and mining. Proposed plant comprises loading hopper and flow classifiers communicated by mineral component ducts each made up of 3D housing with loading chamber and inlet and outlet branch pipes arranged at housing top part for connection to aforesaid duct. The latter communicated via exhaust fan with fine filter. Cold plasma generator to force ionised gas or air components to adapter chamber, is connected to the latter communicated via mineral component duct with classifier the first along the feed of mineral components.
EFFECT: higher efficiency of grading.
