ELECTROMAGNETIC DEVICE Russian patent published in 1995 - IPC

FIELD: crushing dry substances; civil engineering. SUBSTANCE: device has cylindric working chamber 1 cooled by cooling agent and having a loading inlet and container receiving product. The chamber is filled with working bodies 2 from ferromagnetic material and enveloped by electromagnetic system 3 with excitation windings 4 connected with alternating current supply source and mounted to be rotatable about its longitudinal axis. Means for transporting materials in the working chambers is made in form of hydraulic cylinders pivotally connected with housing 5 of the device. The housing end face walls have openings for forced advance of cooling agent. Cone-shaped loading inlet is made in the cylindric working chamber and has removable funnel mounted therein. EFFECT: enhanced effectiveness in producing polydispersional materials. 3 dwg
