Lumps. Meet Your Match.

Process engineers know: lumps are the enemy. That’s because material inconsistency – like lumping – is the enemy of process. The solution? Bepex produces a wide range of equipment to eliminate lumps –  large or small, wet or dry –  wherever they occur while processing. That improves processing and the final product. It protects downstream equipment. And it reduces maintenance, cleaning, and overhead expenses.

Why choose Bepex?

Bepex musters an army of equipment to fight lumps, wherever they appear in your process. Our Granulator grinds lumps from dry solids into a consistent particle size. Three types of Disintegrator mills destroy lumps in wet or dry applications – with a focus on tramp material separation to protect downstream equipment. Our Pulvocron crushes lumps, then uses internal particle size classification to produce fine powders under tight particle specs.  It’s a complete product line, so we can help you engineer the exact process to fit your needs.

Proven Track Record

For almost a century, Bepex Disintegrators and other equipment have been used in challenging applications to delump and homogenize materials.  Our complete product line; compact, easy-to-install design; and reputation for durability, reliability and toughness make us the first choice for delumping processes.

Easy to Clean, Food-Grade Construction

All delumping equipment can be constructed to food-grade specifications.  Bepex delumping mills are designed for easy cleaning, change over, and maintenance.  Tramp material collection systems remove unwanted or unexpected items before they can damage downstream equipment or find their way into the final product.

Pre-Tested Performance

Our delumping products are available for testing in our Process Development Center. Our process design experts will help you examine, design, test, and quantify implementing the right delumping solution – either freestanding or as part of a total processing system – to meet your processing goals.

Process Development

Step 01


All new inquiries begin with a feasibility study. These studies aim to provide preliminary insights into the viability of a commercial process. Using as little as 100 grams of material, we can begin early process design, develop plans for pilot-testing and/or confirmation, and begin providing early economic estimates. Our experience across our wide range of technologies gives us a unique ability to provide quick feedback on the feasibility of your process.

Step 02


From our learnings, we’ll begin the process development work. The primary work in this phase takes place in the form of pilot-scale testing in our Process Development Center. Our pilot tests look a bit different than what you may have experienced in the past. Each test is designed to measure the system performance and feasibility rather than that of any single machine.

Each system is custom assembled for each test. Our goal is to provide as much of a pilot-scale simulation as possible while gathering scale-up data to deliver on commercial capacities. When a certain technology proves ineffective, we’ll draw from our range of options to determine if there is a better fit. The Process Development Center is our sandbox to build, test, and revise to ensure we get every detail right.

Step 03

Budget Evaluation

With a successful pilot simulation completed, we now have everything we need to scale up and provide proposals for capital equipment with included performance guarantees.

Step 04

System Design And Build

After receipt of the purchase order, we begin with both equipment and system engineering. Each proprietary technology we sell is custom-designed and built per application. We do not have any off-the-shelf units. At this stage, your exact system begins to take shape, including auxiliary equipment, process flow diagrams, process and instrumentation diagrams, safety provisions, and more.

Step 05


After delivery and installation of your new system, Bepex will provide a mechanical check to ensure everything is placed according to plan. This is followed shortly thereafter by system commissioning. This is where our pilot-scale simulations become invaluable, as our team of application engineers, controls technicians, and sales engineers begin working with your team to successfully bring your system online.

Step 06


At this point, you’re up and running at rate, producing a quality product, but our work doesn’t stop there. 

Following commissioning, Bepex remains a reliable partner, providing quality OEM parts, immediate field service, process optimization, training, system troubleshooting, and more. We have consistently had high customer retention rates, and we believe it is due in large part to our comprehensive approach to serving our customers long after the original sale.
