Its working principle mainly relies on high-speed rotating blades and a paper feeding system. Here's a detailed introduction to its working mechanism: 1. Paper feeding system: The user places the documents to be destroyed into the paper feeding port of the paper shredder. The automatic paper feeding device, which is usually designed, can continuously and smoothly send the paper into the blade area. 2. Blade system: The core part of the paper shredder is the blade system. These blades are usually made of high-strength steel and are specially treated to improve durability and cutting efficiency. The blades are arranged in a certain order and angle to form a cutting chamber. 3. Cutting process: When the paper enters the cutting chamber, it is rapidly cut into small pieces or strips of paper by the force of the rapidly rotating blades. 4. Paper discharge system: The cut paper pieces are discharged through the paper discharge port, which can be easily collected and handled by the user.
