Case Studies 2025: Successful Implementation of Hydraulic Briquetting Presses

Nestled in the industrial heart of Ohio, a mid-sized metal scrap recycling plant had been struggling with a familiar headache: loose metal shavings, turnings, and powder from machining operations were piling up faster than they could be processed. "We were storing these scraps in giant bins that took up half our warehouse," recalls plant manager Mark Thompson. "Transporting them to the smelter was a nightmare—trucks were only half-full because the material was so bulky, and we were spending $15,000 a month just on hauling." The team knew they needed a way to compact the metal waste, but with a mix of ferrous and non-ferrous scraps, they needed a solution that could handle variable materials without compromising density.

After consulting with a recycling equipment supplier, they invested in a portable briquetting machine l portable metal powder compressor PHBM-003 , a hydraulic briquetter equipment designed for compacting metal powders and small shavings. The PHBM-003 operates at 200 tons of pressure, producing 5kg briquettes that are dense enough to withstand transport and melting. To streamline material handling, they also added a plastic pneumatic conveying system to move the metal powder from collection points directly to the briquetter, eliminating manual carting and reducing dust.

The transformation was immediate. "Within the first month, we saw our storage bins emptying out," Thompson says. "The briquettes stack neatly—we're using 40% less warehouse space. Transport costs dropped by 35% because trucks now leave fully loaded, and the smelter loves the briquettes—they melt more evenly, cutting furnace time by 15%." The plant now processes 800kg of metal scrap per hour, up from 500kg before, and has even taken on new clients thanks to the increased capacity.

Over in Texas, a cable recycling facility specializing in scrap electrical cables faced a dual challenge: handling loose copper wires after stripping and meeting strict air quality regulations. "We use scrap cable stripper equipment to remove the plastic insulation, but the copper wires come out tangled and messy," explains operations director Lisa Chen. "They'd get caught in conveyor belts, and the dust from the stripping process was triggering our air quality alarms. We were risking fines if we didn't fix it fast."

The facility turned to a two-part solution: a hydraulic briquetting machine to compact the copper wires into dense briquettes and an air pollution control system equipment to filter dust and particulates. The hydraulic briquetter, equipped with a variable pressure setting, adjusts to different wire gauges, producing uniform 10kg copper briquettes. The air pollution control system, featuring high-efficiency particulate air (HEPA) filters and a dust collector, captures 99.9% of airborne particles from both the stripping and briquetting processes.

"Our shop floor hasn't been this clean in years," Chen reports. "The briquettes feed smoothly into our melting furnace, and we've reduced copper loss by 8% because there's no more loose wire falling through cracks. The air pollution control system kept us compliant with EPA standards, and our workers no longer complain about dust irritation. Best of all, we're processing 600kg of scrap cable per day, up from 400kg, and selling the copper briquettes at a premium to manufacturers who prefer the consistent density."

A plastic recycling cooperative in California, which collects plastic waste from retailers and manufacturers, was drowning in volume. "We get everything from plastic bottles to industrial packaging—bulky, lightweight stuff that fills up our trucks and warehouses in no time," says cooperative lead Maria Gonzalez. "Transporting loose plastic to our downstream recycler was costing a fortune, and they often rejected loads with too much air, saying it was 'low-density' waste." The cooperative needed a way to densify the plastic without compromising its recyclability.

Their recycling machine supplier recommended a two-step approach: a hydraulic baler equipment for large, hollow items like bottles, and a hydraulic briquetting machine equipment for smaller, flaky plastics like film and packaging. The hydraulic baler compresses bottles into 50kg bales, while the briquetter processes film into 2kg briquettes using a dry process to remove moisture. Both machines feed into a dry process equipment line that sorts and preps the plastic for recycling, ensuring consistency for the downstream facility.

"It's like night and day," Gonzalez laughs. "Our trucks now carry 3x more plastic per trip because the bales and briquettes are dense—we're saving $20,000 a month on transport. The recycler accepts 100% of our loads now, and they've even given us a better rate because the material is prepped. We've expanded our collection routes by 25% and hired two more staff—all thanks to these machines." The cooperative now processes 2,000kg of plastic waste daily, up from 1,200kg, and has become a go-to partner for local businesses looking to improve their sustainability.

A lead acid battery recycling plant in Michigan was focused on safety and efficiency. After using a lead acid battery breaking and separation system to split batteries into lead grids, plastic casings, and acid, the plant struggled with handling loose lead paste and small lead fragments. "Lead dust is a huge hazard—our workers wore respirators, but we still had compliance concerns," says safety manager Raj Patel. "Plus, the loose paste was hard to feed into our rotary furnace for paste reduction ; it would clump or blow around, wasting material and slowing production."

The plant upgraded to a hydraulic press machines equipment specifically designed for briquetting lead paste. The press applies 300 tons of pressure to form 10kg briquettes that are solid and dust-free. To complement this, they added auxiliary equipment like a screw conveyor to feed paste into the press and a dust hood connected to their existing air pollution control system. The briquettes are then fed directly into the rotary furnace, where their uniform size ensures consistent heating and complete reduction.

"Safety is our top priority, and the briquettes have made a world of difference," Patel notes. "Lead dust levels in the air dropped by 70%, and workers no longer complain about eye or throat irritation. The furnace now runs at 98% efficiency—no more clogs or uneven melting—and we're recovering 5% more lead from each battery. We've even reduced our hazardous waste disposal costs because there's less loose paste to clean up." The plant's throughput increased from 500kg to 750kg of batteries per hour, and they've maintained a perfect OSHA compliance record for over a year.
