The 140mm diameter Alrad Belle Promix 2-blade helical paddle is designed for primarily use with the Altrad Belle Promix 1200E and Altrad Belle Belle Promix 1600E range of handheld stirring mixers. It can also be used with other similar stirrer mixers which feature the same compatible M14 female fitting.

It features 2 right hand helical spiral ribbons that pushes material downward (from top-to-bottom) to prevent it from spraying and is therefore best suited for mixing liquids or sticky materials, like paints, plaster, tile adhesives etc.

A 3-blade helical paddle with 3 left hand spiral ribbons that pushes upwards (from bottom-to-top) is also available and is typically used to mix heavy aggregate materials like concrete, mortar, floor screed and other similar less viscous products.
