Building a highly profitable metal recovery facility requires strategic investment in advanced mechanical processing. Modern plants must focus on precise sorting and extraction to maximize the market value of their end products. At MAXIM machinery, we design complete processing solutions that integrate crushing, impurity removal, sorting, and forming into a single automated workflow. Choosing the correct sequence of heavy machinery determines the overall efficiency and profitability of your operation. By engineering robust systems capable of handling capacities ranging from 10 to 50 tons per hour, we help process engineers and investors transform mixed scrap into high-purity raw materials. These clean outputs seamlessly connect to downstream smelting supply chains, offering significant economic returns while actively promoting green and sustainable industrial development.
The foundation of any efficient material recovery facility lies in the initial size reduction stages. Plant investors often debate whether to use both shredding and crushing units, sometimes viewing them as interchangeable. However, these machines serve fundamentally different mechanical purposes within the processing workflow and must be applied sequentially to achieve the desired material liberation.
An industrial shredder operates as the primary volume reduction unit at the very beginning of your processing line. You should deploy this machinery when your incoming feed consists of bulky, dense, or highly tangled waste that cannot be processed safely by high-speed mills. Shredders utilize a low-speed, high-torque shearing action. The heavy-duty counter-rotating shafts are equipped with aggressively hooked blades that grab, pierce, and tear large objects into irregular strips and coarse chunks. This primary stage is not intended to produce a pure commodity; rather, it serves to protect downstream equipment from severe impact damage and blockages.
At MAXIM machinery, we independently develop our shredding blades with wear and impact resistance that significantly exceeds standard industry benchmarks, ensuring continuous operation even when processing complex mixed metal bales.
A metal crusher is specifically designed for secondary size reduction and material densification. Once the primary shredder has reduced the massive waste into manageable strips, the crusher takes over to physically pound the metal into dense, uniform granules or nuggets. This high-speed impact environment is absolutely critical for the liberation process. Liberation is the mechanical separation of distinct elements, breaking the tight physical bonds between metals and attached non-metallic impurities such as plastics, resins, or rubber. Without passing the pre-shredded material through a high-impact crusher, downstream sorting machines will fail to achieve high purity rates because the disparate materials will remain physically fused together.
Following the physical liberation of the materials, the operational focus shifts entirely to automated sorting. We integrate advanced magnetic and conductive separation technologies to continuously divide the mixed waste stream into highly profitable, distinct commodities without requiring intensive manual labor.
Ferrous extraction is the immediate sorting stage following the crushing and liberation process. By installing heavy-duty magnetic separators above the primary conveyor belts, we actively pull scrap steel and iron upward, separating them from the main material flow. This initial extraction phase serves two crucial operational purposes. First, it instantly generates a clean, saleable stream of ferrous scrap ready for direct delivery to steel mills. Second, it acts as a vital protection mechanism for the highly sensitive non-ferrous sorting equipment situated further down the line, preventing heavy iron chunks from causing catastrophic mechanical wear. Our magnetic separation units are fully automated and designed to continuously discharge the collected ferrous materials, easily keeping pace with processing capacities of up to 50 tons per hour.
Once the ferrous metals are successfully removed, the remaining material stream consists of a mixture of non-ferrous elements and non-metallic waste. To efficiently recover these valuable materials, we implement eddy current separation technology. This specialized machinery utilizes a rapidly spinning magnetic rotor housed inside a non-metallic drum. As the internal rotor spins at exceptionally high speeds, it generates a rapidly alternating magnetic field. When conductive non-ferrous metals like aluminum alloy and copper travel through this field, electrical currents are induced within them. These internal currents create their own opposing magnetic field, which violently repels the conductive metals away from the belt into a dedicated collection bin, while the inert plastics and rubber simply fall straight down under the influence of gravity.
Designing an optimal facility requires aligning the mechanical capabilities of the equipment with your specific raw input characteristics and final market objectives. We customize every production layout to avoid the waste and inefficiency associated with one-size-fits-all manufacturing approaches.
Your facility design must begin with a thorough evaluation of your incoming waste composition. A processing plant that primarily receives heavy scrap steel will require extended magnetic sorting zones and robust primary shearing capabilities. Conversely, a facility focused on processing lightweight alloys will require specialized high-frequency eddy current rotors designed for fine particle separation. You must also scale the equipment dimensions to match your target throughput. Our engineering team customizes production lines to process volumes ranging from 10 to 50 tons per hour. Properly sizing the shredding chamber, crusher motor, and conveyor belt widths ensures the continuous, automated operation of the entire system and eliminates restrictive material bottlenecks.
Downstream smelting facilities enforce strict acceptance criteria regarding maximum allowable impurity levels and precise physical dimensions. The combination of your secondary crushing screen apertures and your automated sorting sequence dictates this final material quality. Our integrated processing achieves a continuous sequence of crushing, impurity removal, sorting, and forming to improve metal purity and recycling value. This ensures the output meets the standards for front-end raw materials for metal smelting and directly connects to the downstream supply chain. To optimize this workflow, we equip the machinery with a PLC control system, supporting remote monitoring and fault warnings, which significantly reduces operation and maintenance costs. Environmental compliance is also integrated into the core design. The entire series of equipment complies with national regulations such as the Law on the Prevention and Control of Environmental Pollution by Solid Waste, and emission indicators for dust, noise, and wastewater are certified by third-party testing.

A: An industrial shredder is utilized exclusively for primary size reduction, using low-speed, high-torque shearing to tear large, bulky waste into smaller pieces. A metal crusher operates at high speeds, using severe impact force to smash the pre-shredded pieces into dense, uniform nuggets. This high-impact crushing process is what physically liberates the metal from attached non-metallic impurities.
A: The separator features a high-speed magnetic rotor that creates a rapidly changing magnetic field. When conductive non-ferrous elements pass over this rotor, the alternating field induces currents inside the metal. This creates an opposing magnetic force that actively repels the conductive material, launching it into a separate collection bin while inert non-metals drop straight down.
