Prater Fine Grinders

Produce a fine grind from dry, free-flowing material.

Discuss My Application Product Brochure PDF Product Details

Produce a fine grind from dry, free-flowing material.

Do you need finer powder from a screen-based impact grinder?

Prater fine grinders use a high-speed rotor, stationary grinding surfaces, and screens for single-stage size reduction. Selection starts with the feed properties and the required finished distribution.

Typical application
Review fine grinding of dry food ingredients before blending.

Also known as: Fine grinding mills, high-speed impact grinders.

What this equipment can help you do

Fine size reduction

Review finer grinding requirements against a sample.

Screened discharge

Select the grinding and screen arrangement around the product.

Production fit

Review feeding, collection, cleaning, and throughput together.

How the process works

Feed consistently

Meter dry material into the grinder.

Apply impact

The rotor and stationary surfaces reduce particle size.

Collect the product

Ground material passes through screens into the discharge system.

Materials, industries & equipment choices

Sugar & food ingredients

Dry sugar and suitable free-flowing ingredients where fine powder consistency matters.

Industrial powders

Resins and powder coatings are among Prater’s described fine-grinding applications. Review temperature sensitivity and cleaning.

Configurations to compare

M-series mills from pilot to production scale, screen and jaw combinations, sanitary features, and available shock-pressure-resistant construction.

Inside the M51 fine grinder

Prater walks through rotor and blade access on its M-series grinder. See the internal components and consider the clearance needed for inspection and maintenance. This is an equipment walkthrough rather than a production-rate trial.

Prater application insight

Application example: grinding sugar within a complete system

Prater’s published sugar system combines a fine grinder, rotary airlocks, and a lump breaker. It shows why consistent feeding, air movement, collection, and controls belong in the review alongside the grinder. The manufacturer’s illustration is a system rendering rather than a site photograph.

Configuration & selection

Product: Feed size, flowability, moisture, density, and heat sensitivity.
Grinding goal: Target distribution, capacity, and permitted product changes.
Operation: Cleaning frequency, contact materials, collection, and access.

Options to discuss

Grinder size and rotor arrangement
Screen selection
Sanitary construction review
Feeding and product collection

Send a representative material description, feed and target particle-size distributions, required rate, and a process sketch. Include any cleaning or temperature limits.

Plan your application review

Is a fine grinder the same as an air classifier mill?

They use different methods to control the discharge. A fine grinder uses screens; an air classifier mill uses internal air classification. Compare them using the required distribution and actual feed.

Can we review or test my material before selection?

Share the material, the current process, and measurable acceptance criteria. RTS can discuss the appropriate review and any testing requirements with Prater before a final recommendation.

What about dust collection and process integration?

Include the feeder, collection system, utilities, cleaning needs, and upstream and downstream equipment in the review. Final equipment and protection requirements depend on the complete application.
