A shredder is a device that is very common today not only in private homes, but also in offices. If you are thinking about purchasing this device, then initially you need to familiarize yourself with its characteristics in more detail.
general description
A shredder is a paper shredder. Translated from English, the word sounds like a shredder, or chopper. Depending on the variety, such devices are capable of cutting paper into pieces or strips. Today, such devices are used by representatives of government organizations, as well as enterprises and individuals who need to destroy confidential or private documents, credit cards, accounts, bank statements and other papers that could be used to steal personal data or fraud.
History of creation
The first paper shredder was created by a New Yorker and was a waste paper vessel that improved the recycling method. August Low filed a patent application in February 1909. In August of the same year, a patent was received, but the invention at that time never saw the light of day. Another similar device was based on a hand -made noodle cutter and was made in Germany in 1935. The person who created the device was Adolf Ehinger. Presumably, he needed to get rid of secret documents, which would have avoided harassment by the authorities. After that, Adolf began selling his devices to state institutions and financial institutions, connecting an electric motor to the device. The company, owned by Ehingen, first manufactured the cutting shredder in 1959, and to this day it continues to engage in this activity.
Varieties of Shredders
A paper shredder can be represented by a device that has different sizes and costs. On sale you can find the simplest devices that are designed to destroy several pages. If necessary, you can purchase and quite large machines that are used by representatives of special destruction companies. Such devices can cost up to several hundred thousand dollars, their productivity is a million documents per hour. There are special truck shredders. If we are talking about a conventional device, then it is an electrical device. However, today you can find shredders of this purpose, which provide for manual control. Such units have many blades and special scissors. Machines are classified not only in shape, but also in size.
Shape separation
A shredder is a device that can make strips from a document. Such actions are carried out by means of rotating knives, strips can be restored, so this type of destruction is less safe. Among other things, this method creates the largest amount of waste. A paper shredder - a shredder - can also be represented by a confetti device, which has a pair of rotating drums in its design, they cut pieces that can take the form of rhombuses, parallelograms or rectangles. Chippers form round or rectangular pieces.
The most safe devices
A shredder is a device that is designed to destroy documents to those sizes that will not allow you to restore a sheet of paper. These include granulators and disintegrators. The principle of operation of such machines is based on repeatedly cutting the document until the elements are small enough to pass through the grid. Shredders can also be distinguished; they pass the paper through a special screen, producing shredding.
A paper shredder - a shredder - can also be represented by a cutter that rips a sheet of paper, using rotating knives in the process. Grinders will be cut using a rotating shaft equipped with knives.
Industrial appliances
They are intended for grinding magnetic media, plastic cards, which after the procedure have such a size that provides a third degree of secrecy. This type of device includes crushers that chop wood, waste paper, automotive rubber, leather in large volumes.
Security levels
Shredder - shredder - can provide a different degree of security. If we are talking about the first level, then the result is a strip whose size is 12 millimeters. At the second level, the stripes are 2 times smaller. The next level allows you to get a strip of 2 millimeters, which is already considered confidential. The fourth level is particles whose dimensions are 2x15 millimeters. The highest secrecy is provided by the fifth level, at which the particles have dimensions equal to 0.8x12 mm. Maximum secrecy is the sixth level at which particles have dimensions equal to 0.8x4 mm.
For reference
The shredder, a photo of which is presented in the article, can be made in an alternative embodiment. A similar device uses the method of arson, composting and chemical decomposition in its work.
Varieties by area of use
For use in the home or office, personal shredders are used that are designed to destroy paper in small volumes. This ensures a low level of secrecy. Due to the small size, such devices can even be located next to the desk. You can also find such models that are installed on the trash. Repair of shredders is not needed if they are used correctly. Most often, office appliances, which are used very often, fail. They are intended for collective operation and destroy a large number of documents, providing an average level of secrecy. Archival devices are intended for the destruction on an industrial scale of a large number of documents, magazines and floppy disks, as well as folders and disks, together with internal contents and metal inserts.
Data recovery
Shredders are repaired by specialists; it is best to entrust this matter to professionals. Since in some cases it is not possible to return the equipment to working condition on its own. Manufacturers emphasize that after data destruction, it may be necessary to restore them. If the elements were not mixed, then the remains of the document are close to each other. Recovery can even be done manually. After 1979, US manufacturers added the ability to destroy documents by spraying and chemical decomposition to their devices. It is worth considering that such devices will cost more compared to those that ensure the destruction of not so high secrecy.
Conclusion
An interesting fact is that some companies today offer their services for the restoration of documents. The cost of restoring one sheet that has undergone cross-cutting with blades is $ 100,000. In order to ensure maximum safety, it is necessary to check that the document enters the device perpendicular to the knives.
