Large Metal Hammer Mill URSTAG

Processing scrap iron and car bodies at industrial volumes requires an appropriately sized machine. A high-capacity metal hammer mill (large hammer mill) uses a massive rotor driven by a high-power motor, capable of shredding large quantities of bulky and thick metal waste per hour through impact, with a uniform output fraction prepared for the automatic separation of the metals.

A high-capacity metal hammer mill is the central piece of equipment in industrial-scale metal recycling plants, where the volumes of scrap iron, car bodies, and metal waste processed daily justify a high-throughput machine. The robust construction and the high-power motor ensure continuous operation over long shifts. See the full range of recycling equipment and the solutions for metal recovery.

Key Advantages of an Industrial Metal Hammer Mill

• High industrial throughput, processes large volumes of metal waste per hour, sized for industrial plants.

• Massive high-inertia rotor, the heavy rotor accumulates kinetic energy for a powerful impact on hard and thick materials.

• High-power motor, the high-power drive maintains a constant throughput even with material that is difficult to shred.

• Massive replaceable hammers, high-wear-resistance steel hammers, sized for intense industrial operation.

• Adjustable screen, the output fraction size is controlled through the lower screen.

• Uniform fraction for separation, calibrated material ideal for magnetic and eddy current separation.

• Construction for continuous operation, armored housing and robust components for 24/7 operation.

• Industrial protection systems, anti-overload, anti-unprocessable objects, load monitoring.

Applications for a High-Throughput Metal Shredder

A high-capacity metal hammer mill is used in large scrap iron recycling plants, in industrial auto dismantling centers, and in units that process large volumes of bulky metal waste. At these volumes, a high-throughput machine is essential: an undersized mill would become a bottleneck in the flow, limiting the capacity of the entire recycling plant.

Metal waste management on an industrial scale is regulated at the European level; a high-capacity metal hammer mill delivered in Europe is designed in line with the requirements of Directive 2006/42/EC on machinery. For integration into a complete metal recycling flow, see also the complete industry solutions.

The high-power motor is the factor that allows the continuous processing of hard materials without loss of throughput: when shredding thick structural iron or massive car bodies, an undersized motor would stall or slow down, while a high-power motor maintains the rotor speed and a constant throughput. This ability to process hard material without interruptions is essential for industrial plants.

The massive rotor stores a large amount of kinetic energy, which is released on impact with the material. This high inertia allows the breaking of thick and hard objects that would stop a lighter rotor. The high-inertia rotor is, alongside the high-power motor, the secret to the capacity for processing the most difficult metal materials.

The processing cost per ton decreases with capacity: economy of scale reduces the fixed cost per ton processed, and the optimized energy efficiency of large machines also reduces the variable cost. For operators with large volumes of scrap iron, a high-capacity machine has the best processing cost per ton, quickly amortizing the higher investment compared with smaller machines.

The uniform fraction produced at high throughput optimizes the entire recycling plant: the downstream magnetic and eddy current separators work most efficiently on consistently calibrated material. A high-capacity mill with an adjustable screen produces a high throughput of uniform fraction, maximizing the yield of metal separation in the following stages of the industrial flow.

Processable Materials

How It Works

1. The bulky metal waste is fed into the shredding chamber of the mill.

2. The massive rotor, driven by the high-power motor, spins the hammers at high speed.

3. The hammers strike the material with the force given by the rotor's inertia, breaking it.

4. The fragmented material passes through the lower screen when it reaches the set size.

5. The calibrated fraction is discharged at high throughput onto a conveyor toward separation.

6. The protection systems handle unprocessable objects and overloading.

The PLC system monitors the motor load and the operating parameters. A correctly operated high-capacity metal hammer mill produces a high throughput of uniform fraction, supporting the capacity of the entire industrial metal recycling plant.

Frequently Asked Questions

What capacity does a high-capacity metal hammer mill have?

The capacity is configured according to the project, sized for large industrial volumes of metal waste per hour. The exact capacity depends on the motor power, the rotor size, and the type of material processed. The sizing is done based on your volume and the composition of the metal waste.

Why is a high-power motor needed?

Hard and thick metal materials offer high resistance to shredding. A high-power motor maintains the rotor speed and a constant throughput even with difficult material, while an undersized motor would stall. The motor power is sized for the hardest material in the specification.

How often does it require maintenance in industrial operation?

The main maintenance is the replacement of worn hammers, planned according to the volume and abrasiveness of the material. In intense industrial operation, the hammers are inspected periodically and replaced individually. Major overhauls of the rotor and the drive system are done at planned intervals, without unscheduled stops if preventive maintenance is followed.

What is the difference from a standard hammer shredder?

A high-capacity mill has a more massive rotor, a higher-power motor, and a construction sized for higher industrial throughputs compared with a standard hammer shredder. The main difference is capacity: the high-capacity mill is for industrial plants with large volumes, the standard shredder for medium capacities.
