Evaluating grinding media is a critical part of the analysis.

All Union Process grinding medias are tested for wear,

consistency, reliability of manufacture and suitability for

the specific milling application.

Union Process offers a complete choice of the best

available media. Grinding media can be ordered at the

same time as milling equipment, or obtained separately.

Once the analysis of the application is complete, Union

Process makes its recommendation as to which specific

grinding solution will best meet the

company’s needs. Union Process will

consider the type of mill (small media

mill or wet or dry grinding Attritor),

size of mill (laboratory or production)

or type of processing mode (batch,

circulation or continuous).

Test . . .

Union Process performs a lab test

on the customer’s material in its

fully equipped, technologically

advanced on-site laboratory. Both

wet and dry grinding laboratory

mills are available for testing

customer-supplied materials.

The results are then evaluated

by the customer or analyzed

utilizing advanced instruments and

procedures available in the Union

Process laboratory.

Evaluate . . .

Particle characterization techniques include a laser

diffraction instrument, surface area analyzer, x-ray

sedigraph and Fisher Sub-Sieve, as well as high-power

microscopes and grind gauges.Torque and amperage

may be monitored during the milling process to

calculate power consumption.

The customer receives a detailed lab report that

includes all test data, processing recommendations

and estimated throughputs based on the

customer’s production requirements.

At this point, the customer may decide to

proceed to larger scale evaluation of the

material, utilizing the Union Process pilot

plant. Union Process operates a fully

equipped pilot plant facility which simulates

actual production conditions.The pilot plant

contains mid-size and full-size production

equipment for conducting scale-up studies

or to make larger quantities of test product.

Recommend. . .

Union Process helps customers choose

the most cost-effective milling solution for

their needs, based on test results, plant

requirements, and desired production rates.

If special engineering is required, Union

Process’ team of engineers can design custom

systems to meet any process requirements

or customer specifications.
