A shredder is an office equipment composed of a knife set, a motor, etc., which can be used to cut up paper and prevent information from leaking to achieve confidentiality. The main function of the shredder is shredding paper, a few can be broken CD/VCD, bank cards and so on. The buttons on the ordinary equipment are generally switches, positive rotation, reverse and so on. Medium and high-end shredders also have continuous shredding, anti-jamming function, full load warning, overheating warning and other functions.
1. Type of shredder
- Hand shredders. Hand-powered shredders have a small body size and low efficiency, with the benefit of simple and inexpensive maintenance.
- Tabletop shredders. Small body, can be placed on the desktop to use, suitable for daily office and home use.
- Small personal/home shredder. The model is slightly larger than the desktop type, and the shredding efficiency is also greatly improved, suitable for family and small office use.
- Medium-sized office shredder. The most widely used model with strong applicability, high shredding efficiency and high cost performance.
- Large office shredder. The body is large, suitable for large enterprise office places, can store a lot of paper scraps, reduce trouble, the price is expensive.
2. How to choose a paper shredder?
The basic parameter functions of the shredder include the breakable medium, the confidentiality level, the number of shredding sheets, the size of shredding sheets, the continuous shredding time, the volume, and the shredding speed.
2.1 Standard of shredder
The requirements for shredder shredding vary depending on the industry. There are a total of 7 grades for shredders according to DIN 66399. Level 7 is the highest level of confidentiality. The status of shredded paper under specific criteria is as follows.
- P-1, the shape of shredded paper is mostly strip, the area of shredded paper is less than 2000m square meters, and the degree of confidentiality is 75%.
- P-2, the shape of shredded paper is mostly in strips, the area of shredded paper is less than 800m square meters, and the confidentiality level is 85%.
- P-3, the shape of shredded paper is mostly in strips, the area of shredded paper is less than 320m square meters, and the degree of confidentiality is 92%.
- P-4, the shape of shredded paper is mostly granular, the area of shredded paper is less than 160m square meters, and the degree of confidentiality is 98%.
- P-5, the shape of shredded paper is mostly granular, the area of shredded paper is less than 30m square meters, and the degree of confidentiality is 99.99%.
- P-6, the shape of shredded paper is mostly granular, the area of shredded paper is less than 10m square meters, and the confidentiality level is close to 100%.
- P-7, the shape of shredded paper is mostly granular, the area of shredded paper is less than 5m square meters, and the confidentiality level is close to 100%.
Among them, level 4 and level 5 are more common, and they are enough to cope with the needs of shredded paper in the normal office environment. The secrecy level can reach more than 98%.
If there is a high need for confidentiality, you can start a P-7 shredder. However, the price of the shredder with the confidentiality level to 7 is also expensive.
2.2 Shredding capability
Shredding capacity refers to the paper thickness and maximum number of paper that the shredder can handle at one time, and the amount of shredding paper is the throughput of the machine itself. The general shredder can break 13-15 pieces each time, and the large shredder can break 60-70 pieces each time. Generally, the better the shredding effect is, the shredding ability is relatively poor, such as the nominal shredding capacity of a brand shredder is A4, 70g, 7-9 sheets, which means that the shredder can handle seven to nine sheets of A4 paper with a thickness of 70g at a time. Ordinary office use A4, 70g, 3-4 sheets can meet the needs of daily work, if it is a large office, according to the need to choose the right format and faster shredder. The existing large paper shredder can generally reach 60-70 pieces each time.
Shredding paper must be used in accordance with the shredding capacity that the machine can withstand, so as not to cause the machine abnormal paper jam, motor load is too large to burn and so on.
2.3 Shredder entrance width
Since the area of the computer file is wider than the general office file, usually 9*11 or 11*15, the paper to be chopped must be entered vertically with the incision, otherwise the whole line of text may be intact and the data is exposed; If the opening is too thin, the paper will fold together, reducing the number of broken pieces each time, and easy to lead to the paper stopper, reducing work efficiency. Therefore, the use of special computer shredder, its entrance should be at least 385mm wide, is the minimum standard. The larger the width of the shredder entrance, the more convenient the operation.
2.4 Reverse paper return function
After all, the shredder is a destructive item, so what if you accidentally put the wrong document? In this case, the "reverse paper return" function can be a lifesaver. If it is used in the office, it is best to have this feature.
2.5 Carton Capacity
After increasing your productivity, take a look at how often you dump shredded paper. The size of the volume determines the frequency of the dumping shredder. If the shredder is often used in the office, the bigger the better, the less frequent dumping of waste cartons. If it is used in your own home, the frequency of shredding is low, then you do not need to care too much
At present, some paper shredders will alert when the wastebasket is full, or when the wastebasket is nearly full, and stop working.
2.6 Is it silent?
That's it, shredding efficiency and dumping efficiency. The quietness of our work environment directly affects our mood. In order to respond to environmental protection information, the general shredder department is higher than 62 decibels as the standard, the throughput of the larger shredder sound volume will be larger, but the new trend of design will focus on the low volume, so that office personnel can enjoy and quiet working environment if you shredder frequency is relatively low, the running volume is not particularly important. But if at the end of each month, you have to destroy a lot of retained documents. Choose one that is silent. For the good mood of your colleagues.
