Apparatus for dispensing particulate material and components therefor

摘要

A particular dispensing apparatus ( 10 ) for dispensing with particular refractory material into a gap between a furnace wall and a from includes a platform ( 12 ) removably engaging the upper end of an expendable metal form. A carriage ( 14 ) is pivotally coupled to the platform and is rotatable about a pivot point located generally at the center of the platform. A hopper ( 30 ) is coupled to the carriage. The hopper receives particular refractory material via an inlet and dispenses the particular refractory material through an outlet ( 36 ). A feeder ( 34 ) is coupled to the outlet of the hopper to move the particulate refractory material from the outlet to a dispenser ( 44 ). The dispenser is coupled to the carriage at a distal end of the feeder and is suspended above the lining gap to deliver particulate refractory material into the lining gap. An air extractor device ( 170 ) is coupled to the carriage for removing air from particulate refractory material in the lining gap and for re-compacting the particular refractory material.
