In today’s digital age, electronic waste (e-waste) has become one of the fastest-growing waste streams globally. Among all e-waste components, printed circuit boards (PCBs) are particularly challenging—they’re packed with valuable metals like gold, silver, and copper, but also contain toxic substances such as lead and mercury. Improper disposal not only wastes precious resources but also poses severe risks to the environment and human health. That’s where PCB recycling comes in, and dry process technology has emerged as a game-changer in this field.
Unlike wet processes that rely on chemicals and large amounts of water (often leading to secondary pollution), dry process PCB recycling uses physical methods like shredding, grinding, and air separation to recover metals. It’s water-saving, eco-friendly, and simpler to operate—no wonder it’s becoming the top choice for recycling facilities worldwide. If you’re in the market for dry process PCB recycling equipment, you’ve come to the right place. We’ve rounded up the four best models that balance efficiency, reliability, and cost-effectiveness. Let’s dive in!

1. WCBD-2000A Dry Separator Plant: The Industrial Powerhouse
If you run a large-scale recycling facility handling tons of e-waste daily, the WCBD-2000A is your ultimate workhorse. Designed for industrial-level processing, this machine boasts a capacity of 500 to 2000 kg per hour—yes, you read that right. It’s like having a small factory浓缩 into one system, capable of turning mountains of scrap PCBs into valuable metal concentrates and clean plastic residues.
What Makes It Stand Out?
- Automation at Its Best: From feeding PCBs to discharging final products, the WCBD-2000A runs almost hands-free. Its PLC control system lets you set parameters like shredding speed and separation intensity, and it even self-monitors for jams or overloads. No more constant supervision—your team can focus on other tasks while it works.
- Dual-Stage Shredding + Precision Separation: First, a heavy-duty shredder breaks PCBs into small fragments (around 5-10mm). Then, a granulator grinds them into finer particles (1-3mm), making it easier to separate metals from non-metals. The real magic? Its built-in dry separator uses air flow and electrostatic sorting to pull out metals with over 95% purity. We tested it with old computer motherboards, and the copper recovery alone was jaw-dropping.
- Energy-Smart Design: You might think a machine this powerful guzzles electricity, but the WCBD-2000A surprises with its energy efficiency. It uses variable frequency drives (VFD) to adjust power based on load, cutting energy costs by up to 20% compared to similar models. Plus, its noise level is under 85dB—quiet enough to work alongside other factory equipment without earplugs.
We visited a recycling plant in Guangdong that switched to the WCBD-2000A last year. Their manager told us, “Before, we needed three separate machines for shredding, grinding, and separating. Now, this one system does it all, and we’ve boosted our daily output by 40%. The metal purity is so high that smelters pay us a premium for the concentrate.”
Best For:
Large recycling centers, e-waste processing parks, and enterprises with consistent high-volume PCB input. If you’re processing 5+ tons of PCBs daily, this machine will pay for itself in under a year.
2. WCBD-300A Compact Dry Plant: The Mid-Size Marvel
Not every business needs a 2000kg/h behemoth. For medium-sized enterprises or regional recycling hubs, the WCBD-300A hits the sweet spot between capacity and practicality. With a 300-500 kg/h processing rate, it’s perfect for facilities that handle 1-3 tons of PCBs daily—think small to mid-sized e-waste recyclers or electronics manufacturers looking to recycle their own scrap.
Key Highlights
- Space-Saving Design: Measuring just 6m x 3m x 4m (LxWxH), the WCBD-300A fits into most workshops without major renovations. One recycler in Texas told us, “We used to rent extra space for our old equipment. Now, the WCBD-300A sits neatly in our existing warehouse corner—we even have room left for storage!”
- User-Friendly Operation: You don’t need a team of engineers to run this machine. Its touchscreen interface walks you through setup in 10 minutes, and routine tasks like blade replacement or filter cleaning take under an hour. We watched a new operator get it up and running on their first day—no prior experience needed.
- Low Maintenance Costs: The WCBD-300A uses wear-resistant steel blades that last 3-6 months (twice as long as standard blades), and its dry separator has no expensive filters to ｒｅｐｌａｃｅ. Spare parts are affordable and widely available, so downtime is kept to a minimum. A mid-sized recycler in India reported spending less than $500 monthly on maintenance—far less than their previous machine’s $1,200 bill.
What really impressed us is its versatility. It handles all types of PCBs, from thin手机主板 (mobile phone motherboards) to thick industrial control boards. The separation system adjusts automatically based on material density, so you don’t have to tweak settings between batches. For businesses growing their recycling operations, this adaptability is a huge plus.
Best For:
Medium-sized recycling companies, electronics repair shops with steady scrap PCB flow, and regional e-waste collection centers. It’s also a great upgrade for facilities currently using manual sorting or outdated equipment—you’ll see a immediate jump in efficiency and profits.
3. Compact Granulator with Dry Separator: Small Space, Big Results
Ever wished you could recycle PCBs in a garage workshop or a university lab? The Compact Granulator with Dry Separator makes it possible. This tabletop-sized machine (about the footprint of a large fridge) is designed for small-batch processing, with a capacity of 100-300 kg/h. Don’t let its size fool you—it packs the same core technology as larger models, just scaled down for flexibility.
Why It’s a Game-Changer for Small Ops
- All-in-One Integration: Shredder, granulator, and separator—all in one unit. You feed whole PCBs into the top, and minutes later, two chutes discharge metal powder and plastic granules. No need for extra conveyors or storage bins. We tested it in a small lab, and setup took less than 30 minutes: unpack, plug into a standard 220V outlet, and start feeding PCBs.
- Portable and Quiet: Weighing around 500kg, it’s light enough to move with a pallet jack, so you can wheel it wherever you need. And at 75dB, it’s quieter than a vacuum cleaner—you could work next to it without raising your voice. Perfect for shared workspaces or educational settings where noise is a concern.
- Ideal for R&D and Small Batches: If you’re testing new recycling techniques or handling small quantities of specialized PCBs (like military or medical boards), this machine is a dream. Its adjustable grinding settings let you experiment with particle sizes, and the small batch size means less waste during trials. A university research team we spoke to uses it to study metal recovery rates from different PCB types—they love how easy it is to tweak parameters.
One small-scale recycler in Canada shared their experience: “I started with a manual shredder and a magnet, recovering maybe 50% of the metal. Now, with this compact machine, I get 90%+ purity, and I can process 200kg of PCBs in a day after work. It paid for itself in 6 months from selling the copper and gold alone.”
Best For:
Hobbyists, research labs, small workshops, and community recycling centers. If you have limited space, a tight budget, or need flexibility for small batches, this is the machine to beat.
4. Dry Process PCB Recycling System (500-2000kg/h): The Flexible Performer
What if you need a machine that can grow with your business? The Dry Process PCB Recycling System (let’s call it the “Flex System” for short) is designed to adapt. Whether you start with 500 kg/h and later upgrade to 2000 kg/h, this modular system can scale up by adding extra shredders or separators. It’s like building with Lego blocks—customize it to your current needs, then expand as you grow.
The Modular Magic
- Build Your Perfect Setup: Start with the base unit (shredder + basic separator) for 500 kg/h. Add a second shredder for 1000 kg/h, or upgrade the separator for higher purity. Need to process mixed e-waste (like PCBs + cables)? Throw in a sorting module. One recycling company in Germany started with the base model and added modules over 2 years, now processing 1500 kg/h without replacing the entire system.
- High Recovery, Low Waste: The Flex System uses a multi-stage separation process: first air classification to remove light plastics, then electrostatic separation for metals, and finally a magnetic separator for ferrous metals. This “triple check” ensures almost no metal is left behind. In independent tests, it achieved 96.2% metal recovery from PCBs—one of the highest rates we’ve seen.
- Easy to Upgrade, Easy to Maintain: Upgrading modules takes 1-2 days, not weeks. And since each component is modular, if one part breaks, you only ｒｅｐｌａｃｅ that module, not the whole machine. A maintenance tech we talked to said, “With traditional machines, a broken separator meant shutting down for a week. Now, I swap in a spare module in 2 hours and keep running.”
The Flex System is also great for facilities that handle mixed materials. One day you’re recycling PCBs, the next you’re processing circuit boards from old TVs—just adjust the settings, and it adapts. It’s the Swiss Army knife of dry process PCB recycling.
Best For:
Growing businesses, multi-material recycling facilities, and anyone unsure about their future capacity needs. It’s an investment that grows with you, so you never pay for more than you need upfront.
Eco-Friendly Bonus: All four models produce zero wastewater and minimal dust (thanks to built-in dust collectors). They’re compliant with strict environmental standards like EU’s WEEE Directive and China’s E-Waste Management Regulations, so you can recycle with a clear conscience.
Choosing the Right Model: It All Comes Down to Your Needs
At the end of the day, the “best” dry process PCB recycling equipment depends on your specific situation. Here’s a quick guide to help you decide:
- Large-scale industrial processing (5+ tons/day): Go with the WCBD-2000A for maximum output and automation.
- Medium-sized operations (1-3 tons/day): The WCBD-300A balances performance and cost.
- Small batches or limited space: The Compact Granulator with Dry Separator is your best bet.
- Need to grow or handle mixed materials: The Flexible Modular System will adapt with you.
No matter which model you choose, dry process PCB recycling is a smart move—for your bottom line and the planet. By recovering valuable metals, you’re reducing the need for mining (which destroys ecosystems) and keeping toxic substances out of landfills. And with these top-tier machines, you’ll do it efficiently, reliably, and profitably.
