For Bead Milling Applications
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
HDDM-01
- 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 HD-01 (referred to as HD-01/HDDM)
SDM-5 and SDM-1
- 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
