Printed circuit boards (PCBs) are among the most value-dense streams in the entire e-waste sector. A single ton of scrap boards can hold more copper, gold, silver and palladium than many natural ore deposits, which is why more recycling operators are investing in dedicated circuit board recycling equipment instead of paying smelters to take the material away. But before you commit to a purchase, it pays to understand exactly what types of PCB recycling machines exist and which configuration fits your operation.
San Lan Technologies Co., Ltd, a professional e-waste recycling machinery manufacturer based in Jiangxi, China, has been building circuit board recycling plants since 2007. This guide breaks down the types of circuit board recycling equipment San Lan offers, how they differ, and how to choose the right one for your plant.
Two Core Technology Families: Dry Process and Water Process
At the most basic level, every mechanical PCB recycling line does the same job: it crushes scrap boards, liberates the metal from the fiberglass and resin substrate, and then separates the two fractions. The way that final separation happens splits the equipment into two families.
Dry Process Equipment
Dry process equipment separates metal from non-metal without using any water. It relies on a combination of air classifiers, vibrating screens, cyclone separators and electrostatic separators to sort copper-rich particles from resin and fiberglass powder. Because no water is involved, dry systems have no wastewater to treat, which makes them easier to permit in regions with strict discharge regulations or limited water supply. Modern dry lines also integrate pulse-jet baghouse dust collectors so the whole process stays clean and compliant.
Water Process Equipment
Water process equipment uses water as the separation medium, sorting metal particles from non-metallic fractions through gravity-based classification. Wet separation is especially effective at recovering fine metal particles and can consistently deliver high-purity copper powder. It is a strong choice for facilities that already have water treatment infrastructure in place and want maximum recovery from fine fractions.
San Lan's Circuit Board Recycling Equipment by Capacity
Within those two technology families, San Lan offers a range of plant sizes so you can match your capital investment to your feedstock volume. Here are the main types available.
Entry-Level: WCBD-300A with Dry Separator
The WCBD-300A is a compact dry-separation plant with a capacity of 300 to 500 kg/hour. It is designed for small recycling businesses or operators just entering the PCB recovery market. The line includes an air separator, a dry vibrating screen, an electrostatic separator, a cyclone and a pulse dust collector, so it delivers professional-grade separation results in a footprint that suits a modest workshop.
Mid-Range: WCB-005C, WCBD-1000A and WCB-1000C
For steady commercial volumes, San Lan offers several mid-range options. The WCB-005C is a 500 kg/hour plant with a water metal separator, capable of recycling PCB waste that still carries components and processing roughly 4 to 6 metric tons per 8-hour shift. The WCBD-1000A is a 1000 kg/hour air-separation plant that achieves a recovery rate of around 95% and copper powder purity of 96 to 98% with no dust pollution. The WCB-1000C is the wet-separation counterpart at the same 1000 kg/hour capacity, using a fully mechanical automated process that is stable, easy to operate and environmentally friendly.
High-Capacity: WCBD-2000A and WCB-2000C
Industrial-scale operators processing substantial PCB waste streams can step up to the 2000 kg/hour class. The WCBD-2000A uses third-generation air separation technology and combines an air separator, dry vibrating screen, cyclone separator and pulse bag dust collector to produce copper powder with 96 to 98% purity. The WCB-2000C delivers the same 2000 kg/hour throughput with wet separation, and San Lan can custom-design the plant for capacities anywhere from 300 to 5000 kg/hour to suit unusual feedstock volumes.
The Machines Inside a Complete PCB Recycling Line
A complete circuit board recycling plant is more than a single separator. Whatever type you choose, a properly engineered line integrates several processing stages into one continuous, automated workflow:
- Pre-shredding: a twin-shaft or four-shaft shredder reduces whole boards into manageable fragments as the first stage.
- Secondary granulation: hammer mills or high-speed granulators further reduce particle size to liberate metal from the substrate.
- Classification and separation: depending on the technology path, air classifiers, vibrating screens, gravity tables or electrostatic separators sort the copper-rich fraction from resin and fiberglass.
- Dust collection: pulse-jet baghouse filters and cyclone collectors capture airborne particles to protect workers and meet environmental requirements.
- Control system: a centralized PLC-based control panel lets operators monitor and adjust every stage from a single interface.
How to Choose the Right Type of Equipment
There is no single "best" type of circuit board recycling equipment, only the type that best matches your conditions. Start by estimating your monthly feedstock volume, then work out whether you can support a water treatment loop or would prefer a dry system that avoids wastewater entirely. If you process boards with components still attached, a wet-separation line such as the WCB-005C is often the more forgiving option; if your feedstock is pre-dismantled boards and you want the lowest operating complexity, a dry line like the WCBD-300A or WCBD-1000A is a strong fit.
Capacity is just as important as separation method. A 300 to 500 kg/hour plant suits a small operation, while regional recyclers typically find the 500 to 1000 kg/hour class the sweet spot, and centralized recycling hubs serving multiple collection points usually need the 1000 to 2000 kg/hour class. A professional manufacturer should help you size the plant based on your actual feedstock, floor space and budget rather than selling you the largest machine on the list.
