Small Media Mills: SDM Series Attritors

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

Laboratory Models

01-HDDM Designed for small media from .10mm to 2mm Features a mechanical drive or an electronic variable speed drive system Runs at RPMs from 1000 to 4200 Optional side discharge valve and/or bottom plug valve (both available for stainless steel tanks only) Can be purchased as a combination model with 01-HD (referred to as 01-HD/HDDM)

01-HDDM

05-SDM and 1-SDM Designed for small media from .25mm to 3mm Features a mechanical drive or an electronic variable speed drive system Runs at RPMs from 300 to 2000 Includes discharge valve and media retaining screen
