1. Developing History of Shredder Machine
The first generation of shredders
Most of the first generation of the transmission mechanism is driven by a belt with low noise,
but the belt may be pulled and deformed after long working hours, even the breaking
phenomenon, and the surface of the belt teeth is easily worn and the machine running may
slip.
The second generation of shredders
Plastic gear rolls, because it is difficult to master injection and shrinking process accurately of
the shredder machine, resulting in the low accuracy of the gear itself. And running at high
speed, the noise is large. Due to the brittle plastic parts, poor toughness, it is prone to appear
the phenomenon of broken teeth.
The third generation shredders
Metal sprocket: quiet operation, low energy loss, efficient cutting, and the perfect
coordination of the various components of the system achieve the compelling features.
The fourth generation of shredder machine
The drive mechanism of shredder machine is the metal gear, although the metal gears
overcome the above drawbacks, it is difficult to avoid the impact of the metal gear and friction
sound. Due to the mounting accuracy of the metal bodies, the lubrication conditions of the
gear meshing, technical and maintenance of the lubrication effect and uncontrollable long-
term operation, there will be a lot of noise at high-speed operation.
The fifth generation of shredder machine
Diamond snug movement, it takes use of alloy steel materials, quenching process of metal
tool, completely CNC machining technology, and the workmanship guarantee transmission
installation accuracy, so the wear is reduced to a minimum to ensure the stability of product
quality and reduce noise. We can assurance the quality of single shaft shredder with the
super full rigid all-metal gear which is made of steel roller knife, high quality powerful motor.
The sixth generation of shredders (modern)
Currently, the high-tech multimedia high series grinder has the high technology content which
can be used to broken CD-ROM, floppy disk, tape, video, etc. and the embedded button
panel with a protective film ensure the function of the way forward, rewind, stop, and full stop.
In the modern world, we pay attention to care for the quality of life, we have higher

2. requirements for the environmental protection of the product functionality, performance,
security, therefore, the functions, such as carton storage partitions, motor overheating
protection, load automatic shutdown function, storage carton not closed the automatic power-
off are be more and more used in the room.
