Top 10 Paste Reduction Melting Furnace Suppliers in China | 2025 Rankings and Reviews

Founded in 2003, BERT has grown from a small workshop to a global leader, and it’s easy to see why. What really sets them apart is their rotary furnace for paste reduction l lead acid battery recycling plant —a beast of a machine that can process up to 5 tons of battery paste per hour. But it’s not just about speed; their furnaces use a patented heat recovery system that cuts energy use by 22% compared to standard models. That’s a big deal for recyclers watching their utility bills.

Clients rave about their after-sales support too. “We had a minor issue with the control panel six months in, and their tech team was on a video call with us within 2 hours, guiding us through the fix step by step,” says Maria Gonzalez, operations manager at a major recycling plant in Spain. BERT also holds ISO 14001 and CE certifications, which matters if you’re exporting to Europe or North America. Their focus on sustainability even extends to the materials they use—85% of the furnace’s steel frame is recycled, aligning with the circular economy goals many plants are chasing.

Shanghai LeadMaster has been a household name in the lead acid battery recycling equipment space since 1998, and their paste reduction furnaces are a masterclass in precision. Their flagship model, the LM-PRM 5000, uses a dual-chamber design that first dries the paste (to remove moisture) and then melts it, resulting in 99.97% pure lead output. That’s a level of purity that reduces the need for further refining, saving time and money downstream.

What stands out here is their customization options. Need a furnace that fits into a tight factory layout? They’ll design a compact version. Processing paste with higher sulfur content? Their engineers will tweak the combustion system to handle it. “We work with recyclers in 42 countries, and no two plants are the same,” explains Li Wei, LeadMaster’s sales director. “One size does not fit all, and we’ve built our reputation on that.” They also offer a 5-year warranty on the furnace lining—unheard of in the industry—giving buyers peace of mind.

GreenCycle might be the new kid on the block (founded in 2010), but they’ve made waves with their focus on low-emission technology. Their paste reduction furnaces come with an integrated air pollution control system that captures over 99% of lead fumes and sulfur dioxide. For recyclers in areas with strict air quality laws—looking at you, California and Germany—this is a game-changer. No need to buy a separate pollution control unit; it’s all built in.

Another win? Their user-friendly interface. Even if you’re not a tech whiz, the touchscreen control panel walks you through setup, troubleshooting, and maintenance checks. “Our old furnace had a manual dial system that felt like something from the 80s,” jokes Raj Patel, who runs a recycling plant in India. “GreenCycle’s system lets my team monitor temperatures and output in real time on their phones. It’s like having a smart furnace.” They’re also surprisingly affordable, with prices about 15% lower than BERT or LeadMaster, making them a top pick for mid-sized operations.

Hangzhou MetalMelt has carved a niche for itself with ultra-high-capacity furnaces, and their lead refinery furnace l lead acid battery recycling line is a testament to that. Their largest model, the MM-PRM 8000, can process a staggering 8 tons per hour—perfect for mega-plants handling tens of thousands of batteries weekly. But don’t let the size fool you; it’s surprisingly energy-efficient, using medium-frequency induction heating to target heat directly at the paste, reducing warm-up time by 40%.

What clients appreciate most is their transparency. “They sent us a detailed video of the furnace being built, so we could see the quality of the welds and the thickness of the refractory lining,” says James Wilson, a plant owner in Australia. “No smoke and mirrors—just solid engineering.” MetalMelt also offers on-site training for your team, ensuring everyone knows how to operate and maintain the furnace safely. Their only downside? Lead times can be up to 16 weeks during peak season, so you’ll need to plan ahead.

Shenzhen Eco-Lead is all about innovation, and their latest paste reduction furnace is proof. They’ve integrated AI into the control system, which learns from your operation over time—adjusting combustion rates, feed speeds, and exhaust flow to optimize efficiency. “After three months, our furnace was processing 10% more paste per hour with the same energy input,” says Carlos Mendez, who runs a recycling facility in Mexico. “It’s like having a 24/7 process engineer on staff.”

They also excel in compact design. If you’re working with limited space, their vertical paste reduction furnace stands just 3 meters tall but still cranks out 2 tons per hour. And for recyclers new to the game, they offer a “startup package” that includes the furnace, a small metal melting furnace equipment for secondary processing, and even help with obtaining local environmental permits. It’s this end-to-end support that makes them a favorite for first-time buyers.

TRS has built a reputation for reliability, and their paste reduction furnaces are known to run for years with minimal downtime. One plant in Brazil has been using the same TRS furnace since 2015, processing over 100,000 tons of paste with only routine maintenance. Their secret? High-quality refractory bricks imported from Austria, which can withstand temperatures up to 1,200°C without cracking.

They’re also leaders in compliance. Their furnaces meet the strictest U.S. EPA standards for lead emissions, making them a top choice for American recyclers. “We had an EPA inspection last year, and the inspector was impressed by how clean the exhaust was,” says Mike Thompson, plant manager in Texas. “TRS’s air pollution control system handles it all, so we never have to worry about fines.” TRS keeps things simple, avoiding overly complex features that can break, and that’s a big plus for operators who prefer “set it and forget it” equipment.

Nanjing LeadTech is a hidden gem, especially for small to medium-sized plants. Their entry-level paste reduction furnace starts at a surprisingly affordable price point, but don’t mistake affordability for low quality. It still meets all EU emissions standards and can process 1.5 tons per hour—plenty for a plant handling 5,000-10,000 batteries monthly. What’s more, they offer flexible payment plans, which is a lifesaver for businesses just getting off the ground.

Their customer service is another highlight. “We’re based in a remote area of Canada, and when we needed replacement parts, they shipped them via express courier at no extra cost,” says Sarah Johnson, who runs a family-owned recycling business. “You don’t get that kind of care from the bigger companies.” LeadTech also offers a 3-year warranty on all major components, giving you peace of mind. The only trade-off? Their maximum capacity tops out at 3 tons per hour, so they’re not the best fit for large-scale operations.

Wuhan GreenWorks takes a holistic approach to recycling, and their paste reduction furnaces are designed to work seamlessly with their other lead acid battery recycling equipment —like battery breakers, separators, and lead refining lines. This integration means less hassle for you; the furnace communicates with the upstream equipment, adjusting feed rates automatically if there’s a bottleneck. “It’s like having a synchronized dance floor in our plant,” laughs Ahmed Hassan, operations director in Dubai. “Everything flows without manual intervention.”

They’re also pioneers in low-waste processing. Their furnaces capture over 99.5% of lead dust, which is then recycled back into the melting process—minimizing waste and maximizing your yield. GreenWorks is a bit newer to the global market (they started exporting in 2018), but they’ve quickly built a loyal following thanks to their innovative approach and competitive pricing.

Chengdu Eco-Melt is all about durability. Their paste reduction furnaces are built with a double-walled steel shell and reinforced refractory lining, making them ideal for harsh environments—like the high humidity of Southeast Asia or the extreme cold of Northern Europe. One client in Russia reports their furnace has been running smoothly for 7 years, even with temperatures dropping to -30°C in winter.

They also offer a unique modular design, so you can start with a basic unit and add features (like extra heat recovery or advanced emissions control) as your business grows. “We started small, processing 1 ton per hour, and two years later, we added the expansion module to hit 2.5 tons—no need to buy a whole new furnace,” explains Kim Lee, a recycler in South Korea. Eco-Melt’s only weak spot? Their user manual could use some improvement (it’s a bit technical for new operators), but their tech support team is happy to walk you through any questions.

Rounding out our list is Qingdao LeadCycle, a supplier that prides itself on speed—both in processing and delivery. Their paste reduction furnaces have a rapid setup time (just 48 hours from installation to first batch) and can process 3 tons per hour. They also offer the shortest lead times in the industry—most models ship within 8 weeks, which is a lifesaver if you need to ｒｅｐｌａｃｅ old equipment fast.

Their metal melting furnace equipment line complements their paste furnaces well, making them a one-stop shop for recyclers who need both. “We bought both the paste reduction furnace and the secondary melting furnace from LeadCycle, and the integration was seamless,” says Paulo Silva, a plant manager in Portugal. “Plus, their prices are about 10% lower than similar models from bigger brands.” The only catch? They don’t offer as many customization options, so if you have very specific needs, you might need to look elsewhere.
