FIELD: plants for continuous electric heating and mixing of concrete and similar current- conducting mixes; applicable in preparation of concrete mixes. SUBSTANCE: plant consists of receiving bin, electrically insulated body, single-start screw including shaft and pins located along helical line and installed on internal surfaces of electrodes body. Shaft and pins of screw are made of current conducting material. Pins are mounted on shaft with gap not exceeding size of fine filler from surface of electrodes with possible contact of pins with electrodes through concrete mix. Electrodes are located along helical line with pitch equaling screw pitch. EFFECT: higher intensity of mix electric heating due to periodic increase of current intensity in course of mixing, with simplified plant design and increased its service life. 2 cl, 2 dwg
