Dimensions and weights are approximate.
^Q-03A – Bench Top
^^Q-03B – With gear pump, large holding tank and mounted on frame riser.
Circulation Attritors designated as “QL” include specially configured arms and disks for special applications.
*Less for lined tanks
**With high density media larger than 3/16″, and with QL models, higher horsepower is required
***Pumping rate is somewhat lower with ceramic grinding media or higher viscosity slurries
****Dimensions and weights are for complete system
Wet Circulation Laboratory Mills
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 the Attritor, 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 machine. 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.
Advantages of Using a Laboratory Attritor:
- Fast and efficient grinding
- Numerous options
- Flexibility
- Repeatability
- Scale-up capability
- No premixing
- Easy operation
- Low maintenance
Common Applications for Attritors:
- High tech ceramics
- Paints, toners, inks
- Pigments
- Tungsten carbides
- DSM (mechanical alloying)
- Food products
- Chocolate, confectionery
- Pharmaceuticals
- Chemicals
- Ferrites
- Fibers
- Paper coatings
- Metal powders
- Metal oxides
- Glasses
- Glazes
- Minerals, coal
- Agricultural flowables
Q-03 Mini Laboratory Model
The Q-03 mini laboratory-sized circulation grinding mill is ideal for users who wish to perform lab trials with very small samples (from 1/2 gallon to one gallon) but still gain the advantages of a circulation grinding system. This small research Attritor offers the advantages of a circulation grinding mill including a high circulation pumping rate, narrow particle size distribution, good temperature control and the ability to sample and make formulation adjustments at any time.
Q2 Wet Grinding
This mill is a lab version of the Union Process Circulation Attritor (“Q” machines). The mill comes complete with variable speed drive motor, tachometer, and a 5- or 10-gallon stainless steel jacketed holding tank with anchor stirrer and high speed stirrer. Metal-free systems are also available.
