Prater Lump Breakers

Break up agglomerates so material can flow again.

Break up agglomerates so material can flow again.

Are you breaking lumps rather than making a fine powder?

Prater lump breakers use rotating blades to break agglomerated material by impact and shear. Single- and dual-shaft arrangements can be reviewed around the feed and downstream handling requirement.

Typical application
Break storage or transport agglomerates before feeding the next process.

Also known as: Lump crushers, flake breakers, deagglomerators.

What this equipment can help you do

Restore handling

Reduce troublesome lumps before conveying or feeding.

Define the actual task

Separate deagglomeration from primary fine grinding.

Access planning

Review cleaning and wear-part access for your process.

How the process works

Receive the lumps

Material enters the breaker under the agreed feed conditions.

Break agglomerates

Rotating blades act on lumps within the housing.

Discharge downstream

Material leaves for the next handling or processing step.

Materials, industries & equipment choices

Food & ingredients

Compacted sugar, salt, cereals, or other suitable agglomerated ingredients before feeding or blending.

Chemicals & minerals

Resins, pigments, fertilizers, and filter cakes are among Prater’s listed applications. Describe whether lumps are friable or hard.

Configurations to compare

Single- or dual-shaft machines, Quick Clean designs, optional screens, wear-resistant components, and bag-dump or bulk-bag integration.

Quick Clean lump breaker: equipment overview

Prater introduces the FB12 Quick Clean flake and lump breaker. See the machine arrangement and access features, then discuss your lump size, cleaning frequency, and discharge requirement with RTS.

Prater application insight

Application example: condition sugar before fine grinding

The sugar system described by Prater includes an FB-8 lump breaker ahead of the grinding duty. This is a useful distinction: first break agglomerates that disrupt flow, then use the grinder to reduce the particles themselves. The image is Prater’s illustrated system, not a customer installation photograph.

Configuration & selection

Lump condition: Maximum size, hardness, friability, moisture, and foreign material.
Required result: Acceptable discharge size, capacity, and limits on fines generation.
Process fit: Gravity feed, upstream control, outlet, cleaning, and available headroom.

Options to discuss

Single- or dual-shaft configuration
Blade and shaft arrangement
Screen options where appropriate
Quick-clean and contact-material review

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

Can a lump breaker replace a fine grinding mill?

Start with what the material needs. Breaking soft agglomerates is a different duty from producing a fine particle-size distribution. Share both the incoming lumps and the required discharge.

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.
