Micronizing Fine Grinding

Small Particles. Big Challenges.

Consistent. Reliable. On-spec. The demands placed on fine grinding and micronizing equipment are high, because so is the cost of not getting it exactly right. Off-spec particles or other materials can hamper further processing, damage downstream equipment – or worse – get into the final product. But processing experts know: for reliable, on-spec dependability, Bepex has the equipment, experience, and proven performance to do the job right.

Why choose Bepex?

Fine grinding lies at the heart of many processing applications, either as an intermediate step in processing or to produce a final, salable product. Bepex offers fine grinding and micronizing systems designed for dry or liquid applications. With customers ranging from start-ups to Fortune 500 companies, Bepex is the expert’s choice for hitting exacting product specifications. Made and supported in the USA, Bepex provides support, parts, and service with quality and speed the competition just can’t match.

Dry Fine Grinding

The Bepex Pulvocron defines fine grinding for food and industrial applications which rely on a consistently on-spec fine-ground powder.  High speed impact fractures material into powder. An internal classifier provides instantaneous sorting. Heating the process air stream results in simultaneous drying and milling capable of producing a low moisture, ultra-fine powder and particle sizes on average from a D(50) of 3µm to a D(50) of 100 mesh.

Liquid Fine Grinding

The Bepex RP Disintegrator is an angled hammermill designed for grinding, delumping, pureeing, and homogenizing. The RP mill is widely used across the food, chemical, and mineral industries where operational versatility is required.  Its signature, angled design lends itself to multiple production applications using the same equipment by providing quick and easy access to internals for cleaning, change overs, and maintenance.

Tested, Proven Performance

Bepex fine grinding mills are entirely customizable and designed to fit your application. Multiple fine grinding options are available for testing in our Process Development Center. Our processing design engineers will help you examine, design, test, and quantify implementing the right grinding or micronizing system – either as an integral component of a larger processing system or to produce a final product.

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.
