Step into the world of heavy-duty shredding with our video showcasing a state-of-the-art pre-shredder. Witness the incredible capabilities of this powerful machine as it efficiently tears through electronics and appliances.
The pre-shredding process begins with the material being delivered to the in-feed chute by a crane. As the material slips into the pre-shredder space, it is grasped by shafts 1 and 2, which supply it to the third shaft. The third shaft operates at higher revolutions per minute while the first two shafts hold onto the material.
One unique feature of this pre-shredder is that the shafts run at different speeds and operate independently of each other, allowing for optimal processing of materials based on density and consistency. The high-speed revolutions of the third shaft result in the material being dragged against the sharp teeth of shafts 1 and 2, effectively tearing it apart.
Watch as the pre-shredded material cascades down from the pre-shredder, either into a pit or onto a conveyor belt. If the resistance within the pre-shredder becomes too great or the maximum torque is reached, the shafts automatically reverse. After a few seconds, the fragmentation process resumes in the normal direction. This automated and adjustable process can be repeated as needed.
With no gear connection between the shafts, the pre-shredder can handle different materials, such as mixed scrap metal and various types of electronics. The control system allows for the selection of specific processing programs tailored to different materials.
The pre-shredder is housed in a robust structure with three working shafts equipped with wear-resistant tear cogs. The shaft bearings are located on both sides of the housing, while the front and back walls provide stability and support. The strategically positioned braces optimize the absorption of forces generated during shredding.
Powered by electric-hydraulic engines, the pre-shredder relies on four independent axial piston pumps to deliver the necessary pressure. These components, along with electric motors, valves, and the hydraulic tank, are integrated into a separate basic rack, which can be arranged according to the operator's requirements.
The video also showcases the feeding chute, which can be customized to suit specific needs. The pre-shredder can be installed on a concrete bed with an integrated material payment system or coupled with a conveyor belt for material feeding. The entire power package, comprising the basic rack, electric motors, pumps, valves, and control panel, is designed as a self-contained unit for easy maintenance.
Experience the efficiency and power of this pre-shredder as it tackles electronics and appliances with ease. Witness the relentless tearing and shredding action that makes this machine an indispensable asset for waste processing and recycling operations.
