Injection mechanism for steel fibers falling after perforated isolator with air flow into fresh concrete, comprises isolator rotating around horizontal drum post, which is propelled

摘要

The injection mechanism comprises an isolator (14) rotating around the horizontal drum post (18), which is propelled. The distance between two axially parallel rods (19) of the drum post is proportional to the length of the steel fibers. The rods are fastened with an end on a wheel (20). The container, which rises up for feeding the drum post with steel fibers (26) is not isolated by the ring (22).
