An adapter for enabling grinding of one or more materials using a dual-asymmetric centrifugal mixer, the adapter to be fitted into a container of the dual-asymmetric centrifugal mixer; it has a shell defining an inner compartment; and openings on the shell, wherein the inner compartment is configured to receive the grinding media for grinding the one or more materials, and the openings enable the one or more materials to enter and/or leave the inner compartment for grinding by the grinding media when subject to the centrifugal force applied by the centrifugal mixer while maintaining the grinding media in the inner compartment; method of use thereof.

A horizontal bead mill for dispersing secondary battery materials and a method for dispersing conductive materials using the horizontal bead mill for dispersing the secondary battery materials are provided. The horizontal bead mill includes a vessel including an inlet and an outlet configured to receive disperse media. The vessel is filled with beads. A rotor is rotated in the vessel to rotate the beads to disperse the disperse media. A driving unit rotates the rotor. An inner surface of a sidewall of the vessel is inclined at a predetermined angle for an axis of the rotor in a manner that an inner diameter of the vessel gradually decreases from an inlet side to an outlet side.
