Fujian Ruihong Aluminum Co., Ltd. – 1200 Scrap Aluminum Crusher & 1000 Metal Shredder Case Study

Founded in 2018 and headquartered in the Wendu Industrial Park, Taimushan Town, Fuding City, Ningde, Fujian Province, Fujian Ruihong Aluminum Co., Ltd. (registered capital RMB 10 million) specializes in non-ferrous metal smelting, aluminum rolling and processing, aluminum alloy manufacturing, and the recovery of production-related scrap metal. In recent years, the company has steadily upgraded its production facilities: its 2023–2024 technical transformation project, with a total investment of RMB 96 million, upgraded equipment and environmental protection infrastructure, progressively building a comprehensive capacity of 100,000 tonnes per year of recycled aluminum products, ranging from aluminum ingots and plate ingots to aluminum molds.

Located along the eastern coast of Fujian, Ruihong draws its scrap feed mainly from dismantled parts, factory offcuts, and post-consumer collected material — a highly mixed, wildly varying stream. With the commissioning of a new 80-tonne twin-chamber melting furnace, the plant's appetite for charge material grew sharply, but raw-material preparation could not keep pace. “The furnace got bigger and hungrier, but if the feed wasn't right, it wouldn't flow. Long profiles wouldn't go in, bulky castings melted slowly, and light-gauge stuff just floated at the furnace mouth and burned off. We had to station a worker with a steel bar to poke the charge in — unsafe and dragging down the whole rhythm,” the workshop manager recalled.

In August 2024, Ruihong commissioned a 1200 scrap aluminum crusher and a 1000 metal shredder from Gongyi Haoxing Machinery, dedicated to uniform pre-furnace preparation of all aluminum scrap streams. The line adopts a “shred-then-crush” two-stage relay: the metal shredder first tears long profiles, bulky castings and alloy offcuts into a uniform mid-size fraction, and the crusher then takes the material down to the ideal furnace feed size, with a belt conveyor delivering the finished charge directly to the melting workshop's storage bins. After the two-stage process, what used to be an unmanageable mix of lengths and sizes emerges as clean, uniformly sized aluminum granules — feeding into the furnace far faster and drastically shortening melt cycles.

In the six-plus months since commissioning, raw-material preparation has flipped from a production bottleneck into a smooth-flowing channel. The furnace mouth no longer needs a dedicated worker poking charge, and natural gas consumption per tonne of aluminum has markedly decreased. As the workshop manager did the rough arithmetic: “Before, the furnace was waiting on feed, and the crew was waiting on the furnace. Now the feed outruns the furnace. One crushing line has brought the entire melting shop's tempo up a notch.”
