Two recycling plant operators receive the same batch of scrap cable and used batteries. Six months later, one is delivering copper powder at 98% purity and lead ingots with recovery rates above industry averages. The other is still troubleshooting dust leaks and separation inefficiencies. The difference was not the raw material. It was the equipment line behind the operation.
The global volume of e-waste and industrial scrap continues to rise, but not all recycling machinery turns that challenge into profit. What separates a functional plant from a profitable one is whether the equipment is engineered as a complete system or sold as isolated machines.
From Individual Machines to Integrated Plants
Many suppliers offer single-unit machines. A granulator here, a separator there. The problem appears when the units do not communicate: capacity mismatches, dust control gaps, and material flow bottlenecks that drain margin.
San Lan Technologies Co., Ltd., established in 2007 and based in Ganzhou, Jiangxi Province, China, designs and manufactures integrated recycling plants rather than standalone devices. With a technical team holding master's degrees in mechanical engineering and over 15 years of field experience in e-waste recycling equipment, the company has delivered projects across more than 21 countries, including Singapore, Colombia, Mexico, India, South Africa, and Saudi Arabia.
Cable Recycling: Copper Recovery with Precision
Scrap cable represents one of the most accessible feedstocks in the recycling industry, but only if separation is clean. San Lan's cable recycling equipment ranges from scrap cable strippers for large-diameter wire to compact and industrial granulators with dry or wet separators. Capacities span from 100 kg/hour to 1,200 kg/hour, depending on the model. The dry separation lines achieve copper purity of 96–98% with no dust pollution, while wet separation systems handle more complex cable types, including jelly-filled variants.
The flow is straightforward: pre-chopping or stripping, granulation, then air or water separation. Each stage is matched in capacity so the bottleneck is the feedstock, not the machinery.
Lead Acid Battery Recycling: End-to-End Recovery
Used lead acid batteries (ULAB) contain lead paste, lead grids, plastic shells, and sulfuric acid. Handling them without a closed-loop system creates environmental risk and regulatory exposure.
San Lan's lead acid battery recycling plant covers the full sequence: battery cutting, breaking and separation, paste filtration, de-sulfurization, smelting, and refining. The breaking and separation system processes 1–10 metric tons per hour, separating lead grid, lead paste, PVC/PP plastic, and hard rubber. For smelting, rotary furnaces and blast furnaces are available with lead recovery rates up to 95%. The refinery kettle furnace produces 99.999% pure lead, with electric heating options that cut energy use by 30–50%.
Air pollution control systems and water treatment plants are integrated into the line, meeting environmental discharge requirements without add-on headaches.
Circuit Board and Lithium Battery Recovery
Printed circuit boards (PCBs) carry copper, precious metals, and resin. San Lan's circuit board recycling equipment handles capacities from 300 kg/hour to 2,000 kg/hour, using either dry air separation or wet metal separation. Recovery rates reach 95%, with copper powder purity of 96–98%.
For lithium-ion batteries, the recycling plant processes 500–2,500 kg/hour through discharging, pre-crushing, secondary granulation, and black powder separation. The output includes black mass (nickel, cobalt, graphite), plastic, copper, and aluminum. Air pollution control and pneumatic conveying systems keep the process contained.
Beyond Equipment: EPC and Value-Added Services
San Lan operates as more than a machine manufacturer. The company delivers EPC (Engineering, Procurement, Construction) projects, including customized plant design, installation, and commissioning. For customers entering the recycling business, San Lan can assist with waste material sourcing, investor introductions, and even product off-take for recovered materials such as copper rice, copper powder, and lead ingots.
This full-cycle support reduces the execution risk for new market entrants and simplifies supply-chain management for expanding operators.
Why System Integration Matters
A recycling plant is only as reliable as its weakest subsystem. Dust collection that is undersized for the crusher, a separator mismatched to the granulator, or a smelting line without gas scrubbing will each stall production and invite regulatory attention.
San Lan's approach is to size and integrate each subsystem for the target feedstock and local environmental rules. The result is a plant that starts up faster, runs with fewer interruptions, and meets emission standards without retrofit.
Next Steps
If you are evaluating a recycling project, the first question is not which machine to buy. It is whether your supplier can design the complete flow, from incoming scrap to finished recovered material, with the documentation and field support to make it operational.
San Lan Technologies has built that capability across 60+ product models and 13 categories. To discuss feedstock testing, plant layout, or project financing, contact the team via info@san-lan.com or WhatsApp at +86 139 2377 4083.
