A loop conveyor, nearly round viewed in a plane, has a ring-shaped or loop path for carrying powder material. A material discharge port is provided oppositely to a material receiving port, away by a semicircle therefrom, so that such material may be carried half in the ring-shaped path. The loop conveyor thus arranged is supported by a balance mechanism at two points on the line of the loop diameter which passes the material receiving and discharge ports. The loop conveyor thus balanced rests on a detector, such as a load cell, for electrical detection of a load applied thereto, which is provided orthogonally to the loop diameter. The weight of powder which is continuously carried in a semicircle through the loop path is checked electrically by means of the detector, and a flow rate can be obtained in relation to the weight. A special kind of powder is received and carried continuously in several section rooms formed in the loop path. |
