Size Reduction Technology
Enhance Process Control with In-Line Particle Reduction
The PIPELINE DELUMPER® In-line Processor converts a solids-laden stream into a fully suspended homogeneous flow — instantly. It stops settling out, clustering and over pressure. The reduced particles are entrained in the stream, away from the pipe walls. Scale is dislodged from reactors, silos and tanks and is crushed before it can impede the flow.
The PIPELINE DELUMPER improves product quality, blend and consistency. It instantly reduces tough solids to a uniform output size. This unit improves mixing, drying and dissolving operations. Nozzles are kept clear and sensitive media is protected. The result is reduced downtime, a process that is in better control, and with substantial savings to the operation.
Precision Lump Breakers Built for Continuous Operation
Every DELUMPER® lump breaker is precision machined, assembled, and aligned at our facility in Livingston, New Jersey. Tight tolerances across the cutting elements, shafts, and bearings ensure smooth, low vibration operation even at sustained high throughput. The result is a lump breaker that runs quietly, holds its output consistency over time, and requires minimal intervention between service intervals.
Unlike screen-based designs that can blind, wear unevenly, or generate excess fines, most DELUMPER® models use a positive, once-through reduction action. Material passes through the cutting zone a single time, sized by the geometry of the teeth and combs rather than forced through a screen. This means less heat buildup, less product degradation, and a more predictable particle output across the full range of feed conditions.
Lump Breakers for Sanitary and Regulated Environments
Food, pharmaceutical, and chemical applications often demand lump breakers that meet strict hygiene, cleanability, and traceability standards. Franklin Miller builds DELUMPER® models with fully polished stainless steel interiors, crevice-free construction, and clean-in-place capability so the unit can be sanitized without disassembly. Cantilevered drive designs allow fast access to the cutting chamber for inspection, cleaning, or changeover between product runs. All contact surfaces and fastener placements are designed to eliminate contamination risk and simplify regulatory compliance.
Versatile and Heavy-Duty Multi-Shaft Crushers
When throughput demands exceed what a single shaft lump breaker can handle, Franklin Miller's multi-shaft configurations scale up without sacrificing reduction quality. Two, three, and five shaft models are available in standard and ultra-heavy-duty builds, with capacities reaching 1,000 tons per hour. Each shaft carries individually replaceable, bidirectional cutting teeth arranged in a staggered pattern that balances load across the full rotation, reducing shock, power draw, and wear. The teeth rotate through a heavy bar grating in a self-clearing action that prevents buildup, making these units particularly effective on wet, caked, or compacted materials that would choke lighter equipment.

DELUMPER® Lump Breakers for Every Application
Whether you're processing dry powders, wet sludge, sticky agglomerates, or hard mineral lumps, there is a DELUMPER® lump breaker built for the job. Our lineup spans nine models across single, dual, and multi-shaft configurations, each designed around a specific set of material properties and throughput requirements.The DELUMPER L series uses a rotating drum and sizing comb design for controlled, screen-free reduction with virtually no fines or heat rise. The DELUMPER LP handles tougher, stickier materials at high volume with extended cutting teeth that self-clear through a heavy bar cage. For sanitary applications in food and pharma, the DELUMPER S4 offers clean-in-place capability, a polished stainless interior, and tool-free drum removal. And the Pipeline DELUMPER processes solids directly inside enclosed pipe systems, eliminating settling, blockages, and overpressure.All units can be customized with special alloys, coatings, flange ratings, seals, and drive options to meet your exact process conditions.
Common Questions
Frequently Asked Questions
1What is a lump breaker?
A lump breaker is a size reduction machine designed to break down agglomerated solids, clumps, and oversized particles into a consistent, manageable size. Unlike mills or pulverizers that grind material into fine powder, lump breakers restore compacted or caked materials to their original grain size with minimal fines, heat, or product degradation. They are commonly used in chemical, food, pharmaceutical, plastics, and mineral processing applications.
2What is the difference between a lump breaker and a crusher?
The terms are often used interchangeably. In general, "lump breaker" refers to equipment that reduces agglomerated or caked materials back to a free-flowing state, while "crusher" can describe a broader range of size reduction equipment including jaw crushers and hammer mills used on hard rock and ore. Franklin Miller's DELUMPER® line functions as both, using a controlled, once-through reduction action suited to friable agglomerates as well as tough, hard, or sticky solids.
3How do I size a lump breaker for my application?
Proper sizing depends on several factors: the maximum lump size in your feed, required output particle size, material properties (hard, sticky, abrasive, wet, heat-sensitive), throughput in tons per hour, and installation constraints such as gravity feed vs. inline operation. Franklin Miller's application engineers can evaluate your material and recommend the right DELUMPER® model, shaft configuration, and cutter design. Contact us for a no-obligation assessment.
4What materials can DELUMPER® lump breakers effectively process?
DELUMPER® lump breakers efficiently handle a diverse range of materials including chemicals, food products, minerals, plastics, pharmaceuticals, agricultural products, and more. They are designed to break down lumps and agglomerates, ensuring a uniform particle size and consistency in the processed materials.
5Is there a DELUMPER® lump breaker ideal for inline setups?
Yes, the Pipeline DELUMPER® is specifically designed for inline processing. It reduces solids and lumps within liquid flows, preventing clogs and blockages in pipelines and maintaining continuous, trouble-free operation.
6Which industries commonly use DELUMPER® lump breakers and crushers?
DELUMPER® lump breakers and crushers are widely used across numerous industries, including chemical processing, food production, pharmaceuticals, mining, wastewater treatment, plastics manufacturing, and agriculture. Their versatility and effectiveness make them essential tools for these sectors.
