Prater Hammer Mills

Reduce larger dry particles to a usable grind.

Prater Hammer Mills

Reduce larger dry particles to a usable grind.

Do you need general size reduction before the next process?

Prater hammer mills use rotating hammers and screens to reduce particle size. Full-Screen and Mega Mill designs provide different arrangements for the grinding duty.

Typical application
Reduce dry ingredients before blending or further processing.

Also known as: Hammermills, impact mills, screened mills.

What this equipment can help you do

Practical size reduction

Review the feed size and target grind before choosing a mill.

Screen-based control

Match the screen and hammer arrangement to the required result.

Process integration

Consider feeding, airflow, collection, and service access together.

How the process works

1

Meter the feed

Supply material at a controlled rate.

2

Reduce the particles

Rotating hammers impact material within the grinding chamber.

3

Pass the screen

Material exits through the selected screen into the collection system.

Materials, industries & equipment choices

Food & ingredient processing

Dry cereal ingredients, agricultural products, and suitable food rework. Define the acceptable grind and product temperature.

Biomass & industrial materials

Wood, biomass, chemicals, minerals, and pigments are among Prater’s listed application areas. Review hardness, fibre, wear, and feed variability.

Configurations to compare

Full-Screen G-series and Mega Mill designs; screens, hammers, contact materials, feed devices, and discharge arrangements.

Watch the G5 hammer mill process real materials

Prater demonstrates cookie rework, Parmesan cheese grinding, and PVC milling on the G5. A later segment shows oats on an M21 fine grinder. Use the examples to discuss material response; the video does not establish capacity for your product.

Prater application insight

Plan the complete grinding circuit

A hammer mill needs a suitable inlet and a clear route for the ground product. Use Prater’s system schematic to review how the feeder, mill, air system, and collection equipment connect. It illustrates a process arrangement rather than a photographed customer installation.

Configuration & selection

Feed
Maximum lump size, moisture, density, hardness, and abrasiveness.
Result
Target particle-size distribution, capacity, and acceptable temperature rise.
Installation
Feeder, air assist, dust collection, electrical supply, and screen-change access.

Options to discuss

  • Full-Screen or Mega Mill arrangement
  • Screen opening and hammer configuration
  • Contact materials and wear parts
  • Feed and collection equipment

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

Will a smaller screen always produce the result I need?

Screen opening is one variable. Feed condition, hammer arrangement, airflow, and throughput also affect the result. Share a representative sample and target distribution for review.

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.

PDF Literature & Resources

Manufacturer literature supports the application review. Confirm final performance, dimensions, construction, and options with the quotation.
