How Continuous or Batch Dry Grinding Attritors Work
| Dry Grinding Attritors can be operated in Continuous or Batch operation. For a complete explanation of how Dry Grinding Attritors work in both Continuous and/or Batch operation, please download the Technical Paper “Attrition Dry Milling in Continuous and Batch Modes”. |

Why A Laboratory Attritor?
Union Process customers know
from experience that the Attritor is one of the most versatile
pieces of equipment in their lab. It can be equipped or
retrofitted easily and inexpensively with a wide variety
of components and accessories. With Attritor lab mills,
users can choose wet or dry grinding, introduce inert
atmospheres, operate at controlled temperatures, vary
grinding speed, overcome product contamination, change
media size and type, and get precise energy consumption
information, all on the same lab mill. Results are repeatable
from one test grind to another for maximum credibility.
Finally, the Attritor is ideal for formulating, quality
control, and scale-up studies.

Model SD-1
Laboratory Attritor
The SD-1 Attritor is
a versatile, reliable, rugged lab mill designed
to meet virtually all lab grinding and dispersing
needs – wet or dry, continuous or batch.
It allows easy and precise scale-up to production-size
equipment with reproducible results. It is also
suitable for small production or pilot plant work.
See our Lab Grinding Mills Brochure for information
on the smaller 01-HD Series and a more detailed
description of the many accessories and options
available.

Multi-Tank 01-HD Lab Attritor System
The Multi-Tank 01-HD Lab Attritor System is the ultimate set-up for quality control and test grinding requirements.
- All tanks (expandable from 2 to 6) controlled by ONE power source
- A timing belt assures that all connected Attritor shafts run at the same speed for the same period of time.
Choose standard stainless steel or a metal-free system with all tanks constructed from alumina, zirconia, or Tefzel®.
