4 Best Compact Pellet Mills with Dry Separators

EcoGranulate Mini-D 500

If you're just starting out or have limited space (think garages, small workshops, or mobile units), the EcoGranulate Mini-D 500 is your first stop. Weighing in at under 800kg and measuring 1.8m x 1.2m x 1.5m (length x width x height), it's designed to fit through standard doorways and can even be mounted on a trailer for on-site processing. But don't let its size fool you—this little machine punches above its weight.

How It Works: Dry Separation Simplified

The Mini-D 500 uses a two-step dry separation process: first, a high-speed rotor granulates the input material (think plastic chunks, small circuit boards, or even metal shavings) into uniform pellets. Then, a built-in air classifier—similar to the technology in compact granulator with dry separator equipment—kicks in. The classifier uses adjustable air flow to separate lighter impurities (like dust or small plastic fragments) from denser, usable pellets. The result? Pellets with 95% purity, which is impressive for a machine this size.

Real-World Performance: A Small Recycler's Take

Jake Martinez, who runs a plastic recycling workshop in Texas, switched to the Mini-D 500 last year. "Before, I had a separate granulator and a wet separator—two machines taking up half my shop, and I was spending $300/month on water bills just to clean the sludge," he says. "Now, this one machine does it all. It's quiet, doesn't flood my floor, and the pellets are clean enough to sell directly to manufacturers. I even moved it outside during busy seasons to free up space inside. Best investment I've made."

Pros & Cons

• Ultra-compact design, perfect for tight spaces
• No water needed—saves on utilities and compliance
• Easy to move and set up (no professional installation required)
• Max capacity caps at 500 kg/hour (not ideal for high-volume needs)
• Air filter needs monthly cleaning (small hassle, but necessary for efficiency)

If your operation is outgrowing a starter model but you're not ready for a full-scale industrial setup, the ProPellet CompactDry 1000 hits the sweet spot. At 2.5m x 1.8m, it's still compact enough for most warehouse layouts, but its 1000 kg/hour capacity and advanced separation tech make it a favorite for mid-sized facilities handling mixed materials—think circuit boards, plastic composites, or even small batches of cable scrap.

The Secret Sauce: Multi-Layer Dry Separation

What sets the CompactDry 1000 apart is its triple-stage dry separation system. After granulation, pellets pass through a vibrating screen to remove oversized particles, then enter an air classifier (like the Mini-D, but with adjustable speed settings), and finally a magnetic separator for metal-specific recycling. This layered approach means it can handle trickier materials, like circuit boards with embedded metal components, without relying on water. As one user put it: "It's like having a lab-grade separator in a machine that fits in my back corner."

Why It's a Step Up for Dry Process Equipment

As a dry process equipment standout, the CompactDry 1000 shines in sustainability. It uses 30% less energy than comparable wet-separation models, and its closed-loop air system recycles 80% of the air used in separation, cutting down on dust emissions. For facilities in areas with strict air quality regulations, this is a huge win—no need for extra air filtration units cluttering up your space.

User Love: "It Turned Our Rejects Into Revenue"

Maria Gonzalez, operations manager at a California-based e-waste recycler, shared her experience: "We used to send 30% of our circuit board pellets to a wet separation facility because our old machine couldn't get the purity right. Now, the CompactDry 1000 cleans them in-house to 98% purity—we sell those pellets for 20% more than before, and we've cut out the transport costs. It paid for itself in 10 months."

When you need to boost output without expanding your facility, the UltraSieve DryGran 1500 is the answer. At first glance, its 3m x .2m footprint might make you think, "Is that really compact?" But compared to industrial models that can take up entire rooms, it's a space-saver—especially considering it cranks out up to 1500 kg/hour . It's designed for facilities that process large batches of uniform materials, like plastic flakes, shredded cable insulation, or post-consumer packaging waste.

Power Without the Bloat: How It Maximizes Space

The DryGran 1500 uses a vertical design to minimize floor space—granulation, separation, and pellet collection stack vertically, rather than spreading out horizontally. Its dry separator is a centrifugal air classifier, which spins pellets at high speed to separate impurities by density. This method is faster than traditional air separation, allowing it to hit that 1500 kg/hour mark without sacrificing purity (it consistently hits 97–98% for plastic and 96% for mixed materials).

A Closer Look at the Numbers

The Verdict from a Packaging Recycler

"We process 10 tons of plastic packaging waste daily, and before the DryGran, we had two separate machines taking up half our warehouse," says Raj Patel, owner of a packaging recycling plant in Florida. "Now, this one unit handles it all—we even added a second shift because setup was so easy. The vertical design was a game-changer; we now have space for a storage area we never had before."

Last but never least, the PowerPellet SpaceSaver 2000 . If you need industrial-level output (up to 2000 kg/hour) but refuse to sacrifice half your warehouse, this is the machine for you. At 3.5m x 2.5m, it's the largest on our list, but compared to traditional 2000 kg/hour pellet mills that can span 5m or more, it's still a compact champion. It's built for heavy-duty materials: thick plastic sheets, automotive plastic waste, and even small metal scrap—making it a favorite for mixed-waste facilities.

Tough Materials, Tighter Space: The Engineering Behind It

The SpaceSaver 2000's secret is its integrated design: the granulator, separator, and pellet cooling system are all built into one unit, with shared motors and controls to cut down on redundant parts. Its dry separator is a multi-chamber air classifier with adjustable baffles, allowing operators to tweak separation settings for different materials (e.g., more air flow for light plastics, less for dense metals). And because it's dry process equipment through and through, there's no need for water lines or drainage—just plug it in, load material, and go.

Why It's Worth the Investment

Mark Wilson, who runs an automotive recycling facility in Michigan, sums it up: "We used to have a line of three machines—granulator, wet separator, dryer—to handle our bumper and dashboard waste. It took up 200 sq ft and required constant maintenance on the water system. The SpaceSaver replaced all three, took up 80 sq ft, and our utility bills dropped by $1,200/month. Plus, the pellets are cleaner—our buyers now pay a premium because there's no water damage or residue."
