FILLING DEVICE AT PROFILED ROTATOR BLOWERS

摘要

The filling device is used to increase the coefficient of admission at the suction window and is installed on the suction section of the two-lobes, ROOTS type positive blowers, largely used in the pneumatic transport of powdery materials, in cement flotation, purifying and transport plants, etc. The filling device for positive blowers comprises a section with two hollow lateral ramifications placed perpendicularly on the longitudinal axis of the blower, which is sealed by two pistons. The pistons can be pulled upwards or downwards from the exterior and brings to resonance the gas volumes from the two ramifications.
