Blending : Mixing powder of the same chemical composition but different sizes

Mixing : Combining powders of different chemistries

·         The blade continuously rotates and mixes the powder.

·         Wet or dry mixing is generally employed.

·         For wet mixing water or dry solvent is used to obtain better mixing.

·         Blending and mixing is necessary for

·         Addition of lubricants coats the powders and reduces die wear and lowers pressure required for pressing of powders.

·         Mixing powders of different materials

·         Obtaining uniform distribution of particle sizes.
