Metal Crusher can effectively break large materials into small pieces or particles for subsequent recycling, smelting or reuse. It is driven by a high-speed and high-torque motor, the hammer on the rotor of the crusher hits the metal in the crushing chamber in turn. Under strong impact, the metal is torn, hammered, lumped, crushed into small particles. The scrap metal hammer crusher can peel off the surface dirt such as rust and paint on the surface of the scrap steel during the crushing process, and then under the action of the magnetic separator, high quality and high purity metal particles can be obtained.
Metal Crusher can break metal scraps like metal barrels, broken bridge aluminum, shredded car, etc. Widely used in steel plants, metal smelters, metal foundries, scrap metal recycling stations, metal recycling resources companies, metal products factories, metal processing plants, automobile manufacturers, other industries and fields.

The metal crusher is a powerful industrial machine designed to reduce large metal waste into smaller, manageable pieces for recycling and reuse. It works by feeding scrap metal, such as aluminum, steel, iron, or mixed metal materials, into a crushing chamber where high-strength rotating hammers apply continuous impact force. These forces break down the material into uniform particles, while a screen ensures consistent output size. The crushed metal is then discharged through the bottom outlet, ready for further processing.
With high efficiency, strong crushing capacity, and stable performance, a metal crusher plays a key role in modern scrap metal recycling plants, helping reduce waste volume and improve resource recovery value. Please watch the metal crusher working video below:
1. Uses an automatic operation cabinet, PLC control, has a high degree of automation.
2. The swing hammer and ring hammer are combined, which can crush and knead in one, significantly remove paint and other dirt, and form high-density agglomerated materials, good crushing effect on any high-hardness material.
3. The hydraulic cylinder cover opening device saves time, labor and effort for maintenance.
4. The hydraulic feeding device pre-compresses the material, expands the feeding range and improves production efficiency.
5. The unique chiseling plate design applies secondary shear force to the material.
6. Strong structure, the main body of the equipment is made of thickened steel plate, and the lining is made of high manganese cast iron, to ensure the strength of the equipment.
7. Safety door is set up so that the unbreakable materials can be discharged from the crushing chamber to avoid damage to the crusher.
8. Installed in a foundation, the running is stable and reliable, large torque, high output, low noise and wear resistance.
The internal structure of a metal crusher is engineered for strength, efficiency, and long-term durability in demanding recycling environments. Inside the crushing chamber, a high-speed rotor fitted with heavy-duty hammers with powerful impact and shearing force to break down scrap metal. Wear-resistant liners protect the chamber walls from abrasion, extending the machine’s service life. A robust shaft and bearing system ensure stable rotation under heavy loads, while the screen at the bottom controls the final output size for consistent particle uniformity. The transmission system, driven by a high-performance motor, provides reliable power to maintain continuous crushing performance.
The aforementioned internal components work together in a coordinated and close manner to achieve efficient volume reduction of scrap metal, smooth and stable operation of the equipment, and minimize the maintenance requirements in scrap processing applications.
Below are the typical technical parameters of a metal crusher, which help customers better understand the machine’s performance, capacity, and configuration options. These specifications may vary depending on different models, production requirements, and processing materials. By reviewing the following parameters, users can select the most suitable equipment to match their scrap recycling needs, ensuring efficient operation, stable output, and optimal cost performance.

Our metal crusher is the ideal choice for efficient, eco-friendly metal waste processing. With advanced features, high durability, and energy-saving design, it will help you improve production efficiency, reduce operating costs, and comply with global environmental standards. Our metal crusher has been successfully deployed in Russia, Aruba, and more regions. If you’re interested in learning more or need a quote, please feel free to contact us.
Project 1: In 2024, a scrap metal recycling company in Aruba installed a metal crusher and related recycling equipment at its facility to process engine block, waste drums, and industrial waste.
Project 2: In 2024, a metal crusher was installed in St. Petersburg, Russia to process 15 tons/hour scrap metal and car waste. The system became the secondary crushing equipment in the customer’s recycling line, significantly improving metal recovery rate.
A complete scrap metal recycling line is built around the metal shredder as the primary size-reduction equipment and the metal crusher as the secondary crushing equipment. Scrap materials such as car bodies, steel drums, appliances, and mixed metal waste are first fed by grab crane into the metal shredder, where they are torn into manageable pieces by low-speed, high-torque shafts. The shredded material is then discharged onto a conveyor and passes through a magnetic separator to remove ferrous metals from mixed waste.
Next, the material can enter a metal crusher for further size reduction, improving liberation between different metals. After crushing, additional separation equipment such as magnetic separators, eddy current separators, and air sorting systems are used to separate iron, aluminum, copper, and non-metal residues. Finally, the sorted metals are collected, stored, or baled for resale.
This systematic process increases recycling efficiency, improves metal purity, reduces transportation volume, and maximizes the economic value of scrap metal.
As a professional manufacturer with years of experience, we provide integrated scrap metal recycling equipment tailored for customers planning to start this business. If you want to know more about equipment configuration, quotation, factory layout or technical details, please leave a message or contact us directly—our professional team will provide you with a tailor-made solution as soon as possible!
| Feature | Metal Crusher | Metal Shredder |

| Main Advantage | Fast crushing, uniform output, and excellent volume reduction | Strong tearing force for bulky solid scrap |
A metal crusher is suitable for crushing scrap metals such as steel drums, engine blocks, aluminum cans, metal containers, and light sheet metal. These materials are easily broken by high-speed hammer impact, making them ideal for volume reduction and recycling preparation.
The output size is controlled by the internal screen. Crushed metal pieces are usually reduced to small, uniform fragments that are convenient for magnetic separation, transportation, and further processing in the recycling line.
Depending on the model, a metal crusher can handle approximately 5–20 tons of scrap metal per hour. Capacity varies based on material type, feeding method, and screen size configuration.
A metal crusher uses high-speed rotating hammers to break thin and hollow metals through impact, while a shredder uses low-speed, high-torque blades to tear bulky and solid scrap. Crushers are more suitable for drums, cans, and shells, while shredders handle heavy solid scrap.
The hammers are made of wear-resistant alloy steel designed for heavy impact work. Their service life depends on the material processed, but they are designed for easy replacement and low maintenance downtime.
Yes, a stable concrete foundation is recommended to absorb vibration during operation. Detailed foundation drawings and installation guidance are provided before delivery.
The machine is equipped with safety protection systems such as overload protection, emergency stop devices, and a fully enclosed crushing chamber to ensure safe and stable operation.
Yes, the metal crusher is commonly used as a core machine in scrap metal recycling lines, working together with conveyors, magnetic separators, and other equipment to improve recycling efficiency.
