ROLLER MILL FOR GRINDING OF FREE-FLOWIN MATERIALS, IN PARTICULAR, GRAIN Russian patent published in 2005 - IPC

FIELD: grinding of free-flowing materials.

SUBSTANCE: the roller mill has at least one pair of rollers rotating in opposite directions, with a gap between them for passage of the material subject to grinding, a facility for delivery of the flow of the material subject to grinding between the rollers and a facility for the drive combined with the facility for delivery to produce an oscillatory motion of the facility for delivery, thus, the flow of the material subject to grinding is supplied due to the fall in the gap between the rollers. The facility of the drive has a shaft that is installed with the possibility of rotation on the facility for delivery that is provided with one mass eccentrically installed relative to the axis of rotation of the shaft and fastened on the shaft for rotation together with it. The facility for delivery has a hopper, the means for support has at least one supporting lever hinge-joined to the frame and hopper, and the facility for transmission has at least one pulley, belt transmission, the plane in which the shaft axes are positioned is parallel with the longitudinal axis of the supporting lever.
