Lump Breakers And Flake Breakers

Prater Single-Shaft Lump Breakers (also called Flake Breakers and vice versa) provide a simple, durable, and economical means of conditioning materials that have become compacted or lumpy due to storage, transport, or blending. Simultaneous application of gentle impact and shear results in free-flowing materials with uniform size distribution. Many industries require size uniformity when blending, conveying, and packaging their finished products. Prater Lump Breakers provide cost savings, streamlined operating efficiency, and enhanced product quality.

Prater Dual-Shaft Flake Breakers provide the same benefit as Prater Single-Shaft Lump Breakers yet with a lower profile. Equipped with counter-rotating blades, these flake breakers are ideal for conditioning or granulating materials purposely compacted in densification equipment, recycling, or disposal operations.

These precision tools are helpful with a variety of products, including:

• Sugar
• Salt
• Resins
• Pigments
• Pasta
• Nutraceuticals
• Minerals
• Kiln dust
• Hemp
• Filter cakes
• Fertilizers
• Chemicals
• Cereals
• Ceramic powders

Important features of Prater Lump Breakers and Flake Breakers include:

• Durable, heavy-duty construction ensuring long service lifespan
• Mild steel or stainless steel models available, depending upon the application
• Easy installation and maintenance
• Easy replacement of internal components
• A wide spectrum of blade designs, tailored for the specific application
• Externally mounted bearings with optional air-purge seals to mitigate contamination
• Customizable screen sizes for any sizing application
• V-belt, cogged belt, or direct drive designs available
• Low-profile design fits in tight spaces, simplifies installation
• Optional wear liners and wear-resistant blades available
• Quick-clean capability for minimizing downtime
• Sanitary construction options as required by the application
• Integrated designs with bag-dump workstations or bulk bag unloading systems available
• Superior de-lumping for optimized product handling
• Heavy-duty dual- or single-shaft models available

Material is gravity-fed into the top of the unit where rotor blades impact the lumpy or compacted material. Blades intermesh with each other or with stationary blades to ensure sufficient material contact. For harder lumps, an optional screen can be used to extend retention time. Fully de-lumped material exits by gravity discharge through the optional  screen. Screens with different openings are easily  interchanged to accommodate a variety of material types and to allow for specific output characteristics. Large operating clearances and low operating speed minimizes shear and impact that eliminates  dust generation and size reduction of particles.

The accompanying schematic illustrates how Prater Lump Breakers and Flake Breakers can be integrated into your total operating system:

Prater Lump Breakers are functional, economical and designed to tear through most materials and reduce them down in size as small as 1/16” without generating excessive dust. Our Lump Breaker design is proven to provide a simple and efficient process of reducing compacted materials into a smaller and controlled granulated product allowing for more efficient and effective product handling by downstream equipment. Prater Lump Breakers reduce downtime, increase performance, and improve product quality over other available lump breakers and crushers.

It is no surprise, with industry-leading reliability such as counter-rotating dual shafts, outboard bearings, and a direct coupled drive, that companies around the world are taking advantage of the many benefits associated with using our innovative lump breakers in their line of processing equipment.
