2 common powder mixing challenges – and how to solve

Batch mixers, with the mixing unit inside the mixer tank, are the ideal solution when dealing with difficult powders and highly viscous products. Dosing powder on the liquid surface and transporting it quickly down towards the mixing head in a controlled vortex achieves optimal wetting of powder by ensuring maximum exposure to the liquid medium.
