EXAKT Three Roll Mill with topical

EXAKT three ointment mills deliver results that are consistent and reproducible.

A comparative study conducted at the University of Hamburg, Institute of Pharmacy in Hamburg, Germany concluded that the quality of ointments processed with EXAKT ointment mills is better than those processed with electric mixing systems. The study highlighted the following conclusions:

  1. The particle size is smaller and the particle size distribution is narrower.
  2. Ointment stability is better.
  3. Temperatures do not increase significantly during processing.
  4. Ointments are softer consistency with lower flow limits.
  5. Ointment mills allow for quality control during processing.

What does an ointment mill do?


An ointment mill utilizes high shear force to disperse active ingredients, and homogenize viscous materials. Shear force is created by three horizontally positioned rollers rotating in opposite directions and at different speeds relative to each other.

The product is pulled through the gaps between the rollers. Active ingredients and powder clumps are broken up and homogenized, which removes grittiness and results in a high-quality topical.  This gives your customers a pharmaceutically elegant and effective ointment.

Elegant Ointments

EXAKT ointment mills produced ointments with softer consistency and lower flow limits than those produced with EMPs, most likely due to the significant temperature increase of ointments processed with EMPs (electronic mortar & pestle).
