Small Media Bead Mills (SDM)

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.

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

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

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)

• 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

SDM-1

• Tank tilts for easy cleaning
• Includes side slurry discharge with media retaining screen
• Tank jacketed for efficient cooling
• Bottom media discharge valve
