The scrap shredder that I propose is a robust and high-performance machine, designed to process heavy metal materials and other types of scrap efficiently. We are talking about an ideal machine for those who need to manage large volumes of demolition or recycling materials. A solid investment, especially considering the installed power and the generous dimensions of the grinding chamber.

Visual description and components

Visually, this shredder presents itself with a massive and well-designed structure, with a grinding chamber measuring 1800x1600 mm . This size guarantees a large load capacity and allows you to process even large pieces without difficulty. The main body is made of wear-resistant steel, with cutting blades made of high-strength material which ensure durability over time even in demanding working conditions.

The shredder is equipped with two motors of 200 kW each , for a total of 400 kW of installed power. This configuration provides high torque and force, necessary for shredding heavy materials such as steel, iron and other resistant metals. The torque generated by the two motors is perfectly balanced to avoid overloads and improve operating efficiency.

Mechanical characteristics

Mechanically, this shredder is a real beast: the powerful motors and quality cutting blades allow it to handle a wide range of materials, including steel, aluminium, cast iron and other types of scrap metal. The blades, mounted on sturdy cutting shafts, work in synergy to ensure uniform volumetric reduction of the material. The transmission is gear driven, ensuring power distribution evenly on both shafts.

The structure is also designed to resist torsional stress and vibrations, minimizing wear on the mechanical components and thus ensuring a long operational life.

Usage procedure

The operation of the shredder is simple and direct: the material is loaded into the grinding chamber, where the blades grab it and begin the shredding process. The shredded material is then expelled through special channels. The control panel allows you to adjust various operating parameters, such as the rotation speed of the shafts and the working pressure, to adapt to the different types of materials to be processed.

Accessories and combinations

Among the accessories available for this type of shredder, automated feeding systems can be combined to ensure a continuous flow of material in the grinding chamber. In combination with the shredder, conveyor belts can also be installed to facilitate the unloading of the processed material, and suction systems for managing the dust produced during the shredding process.

Optimal usage parameters

To maximize the efficiency of the shredder, it is important to correctly adjust the rotation speed of the shafts based on the type of material. An example of a useful formula for determining the optimal speed can be:

$$v$$

Where:

• v is the angular velocity of the trees,
• T is the torque produced by the motors (in Nm),
• r is the radius of the cutting trees.

Furthermore, it is essential to monitor energy consumption and keep operating temperatures constant to avoid overheating which could compromise the life of the motors and blades.

Maintenance

Maintenance of the shredder is relatively simple, but essential to ensure its durability and efficiency. The blades must be checked and sharpened periodically to prevent them from losing effectiveness. Drive shafts must be lubricated regularly to prevent excessive friction which could lead to premature wear. The motors require periodic maintenance to check the integrity of the electrical components and connections.

Safety regulations

As regards safety regulations, if the shredder is not CE , it is essential to adapt the machinery to current regulations by installing protections for the moving parts and emergency devices that immediately interrupt the operation in the event of malfunctions. Furthermore, there must be an overload protection system that avoids damage to the motors and other mechanical components.

Sectors of use

The scrap shredder is mainly used in the recycling and industrial waste management sector. It is perfect for companies that operate in the demolition of metal structures, on construction sites, or in metal recovery plants. Thanks to its ability to reduce the volume of scrap metal, it is an indispensable machine for those who have to manage large volumes of waste.

Why it is better to buy it used

Purchasing a used scrap shredder is an extremely advantageous option. Machinery like this is built to last for years and resist wear and mechanical stress. Buying a quality used shredder allows you to get a high-performance machine at a significantly lower price than new, without compromising operational efficiency.
