Bale & Block Grinding

The Best Way to Break Up the Big Stuff

Reducing large, bulk materials like bales or blocks for further handling is the first step in many processes. Bepex has two field-proven solutions to grind bulk materials into a smaller size for efficient processing. Our Extructor is a sanitary block grinder, primarily used for food applications. Our Rubber Chopper is designed to reduce bales of natural or synthetic rubbers to a small crumb size. In both applications, the primary goal is to increase the available surface area, providing more efficient downstream processing.

Why choose Bepex?

We love breaking big stuff apart. But, being Bepex, we also love doing it efficiently. Our block and bale grinders feature a high-torque, low-speed design. The high torque provides maximum power with a minimal, compact footprint. Low speed prevents excessive, unwanted heat generation which can degrade material or complicate downstream processing. Plus our low-speed operation decreases maintenance and increases component life in what are often demanding applications.

Dependable Reliability

Block and bale grinders usually are found at the start of a process line. If they go down, your line goes down. Bepex grinders’ rugged construction; low-speed, high-torque operation; and easy-to-maintain designs ensure continuous, dependable operation.

Increased Productivity and Profitability

Grind large blocks into smaller chunks to improve downstream processing efficiency. Debottleneck downstream processes and protect equipment for excessive wear.  The result is lower downstream energy requirements, reduced utility bills and maintenance, improved environmental sustainability, and more product out the door.

Process Flexibility

Bepex grinders are available in many different configurations to meet your specific needs. At our Process Development Center, our design experts will help you consider, design, test, and quantify implementing the options needed to meet your processing goals.

Tools to Handle the Biggest Size Reduction Challenges

Extructor Sanitary Block Grinder


The Extructor food-grade grinder reduces the size of large blocks of frozen meats, fruits, or vegetables, or wheels of cheese ahead of downstream cooking. The reduced feed size exposes more surface area to decrease cooking and blending time.

Rubber Chopper Rubber Bale Grinder

Rubber Chopper

The Rubber Chopper reduces bales of synthetic and natural rubber to small, less than inch-sized pieces. The low-speed, high-torque design minimizes heat generation while providing massive grinding power. The smaller feed size speeds material dissolution prior to blending and compounding.

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.
