Abstract:
An apparatus for high-energy and superfine milling of solids, comprising:a housing forming a milling vessel having a horizontal axis and horizontally spaced end walls;a loose charge of milling bodies in said housing;a rotor having a shaft rotatable about said horizontal axis and formed with agitator arms in said vessel for agitating said bodies;seals hermetically sealing said shaft in said housing, said housing having a closable opening for selectively introducing said milling bodies into and discharging said milling bodies from said vessel;a vertically upwardly extending linear tubular inlet fitting tangentially opening into said vessel and having an axis tangential to an outer circular orbit of said agitator arms for feeding solids to be milled into said vessel;a vertically upwardly extending linear tubular outlet fitting tangentially opening into said vessel and having an axis tangential to said outer circular orbit of said agitator arms for withdrawing milled solids from said vessel, said inlet and outlet fittings being spaced inwardly of the respective end walls, axially from one another and on opposite sides of said axis; andducts connecting said fittings in a milling circulation including a blower for forcing a gas through said circulation and a sifter for separating fine particles from coarse particles entrained in said gas.
