A scrap aluminum shredder is a mechanical device specifically designed for crushing and shredding scrap aluminum materials and is widely used in the recycling and processing of scrap aluminum.

A scrap aluminum shredder primarily shreds aluminum through the rotation and shearing force of its blades. A motor drives the main shaft, which rotates at high speed with it. Once the scrap aluminum enters the shredding chamber, it is sheared, squeezed, and torn by the rotating blades, breaking it into relatively uniformly sized pieces.

Structural Components of a Scrap Aluminum Shredder:

• Feed System: This includes a feed hopper and conveyor system, ensuring a uniform and stable flow of scrap aluminum into the shredder's shredding chamber. The design of the feed hopper must consider the feeding method and prevent material splashing. Conveying systems can include belt conveyors, vibrating feeders, and other options depending on the specific situation.

• Shredder Chamber: This is the primary working area for shredding aluminum scrap, housing components such as blades and spacers. The structural design of the chamber significantly impacts shredding efficiency and effectiveness. A suitable chamber shape ensures sufficient shredding of the scrap aluminum within the chamber.

• Blade system: This is the core component of the shredder, directly contacting and cutting the aluminum scrap. The blades are typically made of high-strength alloy steel and undergo a special heat treatment process, resulting in high hardness, high wear resistance, and good toughness. The blade shape and arrangement are designed according to the type of aluminum scrap and the shredding requirements.

• Drive system: This primarily consists of a motor, a reducer, and a coupling. Its function is to transmit the motor's power to the main shaft, enabling the blades to rotate at an appropriate speed. The reducer reduces the motor's speed while increasing the output torque to meet the power requirements for shredding the aluminum scrap.

• Discharge system: This is responsible for discharging the shredded aluminum scrap from the shredder. Discharge methods include deadweight discharge and forced discharge. The discharge port size can be adjusted as needed to control the particle size of the discharged material.

Aluminum shredders are suitable for a variety of aluminum scrap materials:

Household aluminum scrap:
Aluminum cans, used aluminum pots and pans, aluminum door and window fragments.

Industrial aluminum scrap:
• Automotive aluminum alloy parts: engine blocks, wheels, radiators, etc.
• Aerospace aluminum alloy scrap.
• Aluminum housings for electronic appliances: such as computer cases, TV cases, and mobile phone charger cases.

Other aluminum scrap
• Aluminum profile scraps.
• Aluminum cables: discarded aluminum wire and cable.
