<p>PURPOSE:To provide a seal rotary feeder capable of reducing the leakage amt. of the atmosphere on a downstream side to the area on an upstream side. CONSTITUTION:A rotor 13b having blades 13b1 is arranged in a casing 13a. The blades 13b1 come into contact with the casing 13a on the sending side of the rotor to feed the material in the feed chamber 13d demarcated by the rotor and the blades from a material supply port 13a1 to a material discharge port 13a2. The blades are drawn into the rotor on the return side of the rotor and the rotor directly comes into contact with the casing to certainly prevent the leakage of the atmosphere on a downstream side to the area on an upstream side.</p> |
