METHOD AND DEVICE FOR EXFOLIATION OF LAMINAR MATERIALS IN ROD DRUM MILL Russian patent published in 2024 - IPC B02C17/00 

FIELD: various technological processes.

SUBSTANCE: group of inventions relates to a rod drum mill and a method for exfoliation of laminar materials in a rod drum mill. Rod drum mill comprises the main drum and even number of additional drums arranged inside the main drum, rotation drive, initial material loading unit, finished material unloading unit, rods interconnected by flexible links and located inside the drums. Drums are made in the form of truncated cones with inclination angles, forming to the drum axes from 1 to 5 degrees, the main drum is located with a larger diameter on the side of the unloading unit, wherein when additional drums are numbered starting from the main drum with odd numbers, larger diameters are located on the side of the unloading unit, while larger diameters of additional drums with even numbers are located on the loading side. Besides, the mill is equipped with additional units for dosed supply of partially processed mixture, which are installed on the side of smaller diameter of the drum. Method of exfoliation of laminar materials in the above-described rod-type drum mill consists in the fact that into each next additional drum from its loading edge the partially processed mixture is additionally supplied in the volume directly proportional to the difference of working volumes between this additional drum and the previous additional drum.

EFFECT: mill is characterized by increased productivity.
