Abstract

The invention relates to a method and a system (10) for forming pressed articles by pressing powder or granules, the system comprising the following apparatuses: a powder discharge assembly (12); a no-cavity press assembly (20) including: an bottom plate (22) that is the same size or greater than the pressed articles, a constraining means to isolate a portion of powder, and a top punch (24); and a conveyor (14) to transport the powder and/or pressed articles.

IPC Classes  ?

• B30B 15/32 - Discharging presses
• B30B 11/02 - Presses specially adapted for forming shaped articles from material in particulate or plastic state, e.g. briquetting presses or tabletting presses using a ram exerting pressure on the material in a moulding space
• B30B 11/14 - Presses specially adapted for forming shaped articles from material in particulate or plastic state, e.g. briquetting presses or tabletting presses using a ram exerting pressure on the material in a moulding space co-operating with moulds on a movable carrier other than a turn-table or a rotating drum
• B28B 13/02 - Feeding the unshaped material to moulds or apparatus for producing shaped articles
• B28B 3/02 - Producing shaped articles from the material by using presses; Presses specially adapted therefor wherein a ram exerts pressure on the material in a moulding space; Ram heads of special form
• C04B 33/00 - Clay-wares
• C04B 18/08 - Flue dust
• B28B 3/12 - Producing shaped articles from the material by using presses; Presses specially adapted therefor wherein one or more rollers exert pressure on the material
• B28B 5/02 - Producing shaped articles from the material in moulds or on moulding surfaces, carried or formed by, in or on conveyors irrespective of the manner of shaping on conveyors of the endless-belt or chain type
• B30B 15/30 - Feeding material to presses
