Small Media Mills: SDM Series Attritors

For Bead Milling Applicaions

A Hybrid Design

The SDM line from Union Process is a hybrid design that couples the grinding features of a batch Attritor with the performance features of a bead mill.

The Advantages of a Batch Attritor . . .
SDM Attritors share many of the same advantages of batch
Attritors including:

  • No expensive shaft seals to maintain
  • Simple operation
  • Energy efficient
  • No premixing requirement
  • Minimum maintenance required
  • Rugged construction
  • Material can be inspected and additions can be made at any time during the grinding cycle
  • Compact design
  • No special foundation needed

. . . with the Added Features Necessary to Accomplish Bead Milling
Additional advantages of the SDM design are:

  • Specially designed shaft and Delta Discs configured to accommodate small media milling (using mini media from 0.25 to 3mm)
  • High shaft speed (from 400 to 4000 RPM) to energize small media
