CONTINUOUS PLANETARY MILL Russian patent published in 1995 - IPC

FIELD: milling equipment. SUBSTANCE: planetary mill ensures continuous delivery of ground material into milling drums. For this purpose the loading unit 14 secured on carrier 4 has inlet pipe 15, distributing pipes 16 with horizontal channels 17 consisting inside of horizontal sections shaped like a logarithmic spiral, and with inclined outlet channels 18. Baffle plates 19 are installed at the outlet from horizontal channels. The mill has stationary cone 22 with α angle at the apex ranging from 0 < α < 180^° and a bushing 20 shaped like a truncated cone which forms a narrowing circular slot 25 around the cone 25 with a convergence angle of β lying within the limits 0 < β < 12^°, located before the inlet of horizontal channels 17. Outlet channels 18 before the entry into the throats 7 of milling drums 6 are set at an angle of γ to the axis of the mill, said angle ranging from 6^°30″ < γ < 90^°. EFFECT: improved design. 2 cl, 2 dwg
