Manufacturing of aluminum flake powder from foil scrap by
Aluminum flake powder can be produced using aluminum foil scrap in the dry ball milling process. During the ball milling the foil is laminated, micro-forged, cracked continuously, and then finally formed into a flake shape powder.The process of ball milling involves the grinding and mixing of metal particles within a ball mill, which is a type of equipment used for grinding, with the aim of producing a fine powder . This method has been Producing Metal Powder from Machining Chips
