METHOD OF INDUSTRIAL CENTRIFUGE BASKET PERFORATION

A method for making a cylindrical centrifuge basket according to the present disclosure includes pre-perforating a metal sheet to form a perforated metal sheet having perforations aligned along rows extending across a width of the perforated metal sheet. Each row is skewed at a prescribed nonzero skew angle relative to a surface line on the perforated metal sheet, the surface line parallel to an axis of rotation of the cylindrical centrifuge basket. The method further includes roller forming the perforated metal sheet to produce a perforated basket wall sheet, coupling a first edge of the perforated basket wall sheet to a second edge of the perforated basket wall sheet to form a cylindrical basket wall, and coupling a first end of the cylindrical basket wall to a ring, coupling a second end of the cylindrical basket wall to a baseplate, or both to form the cylindrical centrifuge basket.
