摘要

The device uses an air flow. This is fed into a channel, the grain is also introduced into the channel, which has a cone-shaped connector. The wall of the connector (4) is formed as an arched curved section (3). Its curvature is directed towards the channel axis (4). Due to this, the cone type tube nozzle (6) has a bulge-like shape (3a), with a cylindrical section (7) connected to it via an even joint part (8). USE/ADVANTAGE - For transportation of coal dust, grain, etc.. Deposits in connector are prevented.
