A shredder is what? Shredder paper shredder

A shredder is a device that is very common today not only in private homes, but also in offices. If you are thinking about buying this device, you should first become more familiar with its characteristics.

general description

A shredder is a device for grinding paper. Translated from English, the word sounds like a chopper, or chopper. Depending on the variety, similar devices can cut paper into pieces or strips. Today, such devices are used by representatives of government organizations, as well as businesses and individuals who have the 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 shredder for paper was created by a resident of New York and was a container for waste paper, which improved the method of disposal. The application for patent August Lowe filed in February 1909. In August of the same year, the patent was received, but the invention at that time did not see the light. Another similar device was based on hand- type lap-shirts and manufactured in 1935 in Germany. The person who created the device was Adolf Ehinger. Presumably, he needed to get rid of secret documents, which would avoid persecution by the authorities. After that, Adolf began to sell his devices to state institutions and financial institutions by connecting an electric motor to the device. The company, which owns Ehingen, first produced a 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 most simple devices that are designed to destroy several pages. If necessary, you can buy and large enough machines that are used by representatives of special destruction enterprises. Such devices can cost up to several hundred thousand dollars, their productivity is one million documents per hour. There are special shredders and trucks. If it is a conventional device, it is an electrical device. However, today it is possible to meet shredders of such designation, which provide for manual control. Such aggregates have a lot of blades and special scissors. Machines are classified not only in shape, but also in size.

Separation by the form of elements

The shredder is the device that can make strips from the document. Such actions are performed by rotating knives, the strips can be restored, so this type of destruction is less secure. Among other things, this method creates the largest amount of waste. Paper shredder - a shredder - can also be represented by a confetti device that has in its design a pair of rotating drums, they cut pieces that can look like diamonds, parallelograms or rectangles. Devices-crushers form round or rectangular pieces.

Maximum safety devices

A shredder is a device that is designed to destroy documents to the extent that they can not restore a piece of paper. This includes pelletizers and disintegrators. The principle of operation of such machines is based on multiple cutting of the document until the elements are small enough to go through the grid. You can also select grinder-shredders, they pass the paper through a special screen, producing grinding.

Paper shredder - a shredder - can also be represented by a cutter, which tears a piece of paper, using rotating knives during this process. The grinders will be cut using a rotating shaft equipped with knives.

Industrial Appliances

They are intended for grinding magnetic carriers, plastic cards, which possess after the procedure such a size that provides a third degree of secrecy. To this variety of devices can be attributed to crushers, which crush wood, waste paper, automotive rubber, leather in large volumes.

Safety Levels

Shredder shredder can provide a different degree of security. If it is a question of the first level, then, as a result, bands are obtained, the size of which is 12 millimeters. At the second level, the bands are 2 times smaller. The next level allows you to get a 2 millimeter strip, which is already considered confidential. The fourth level is particles, the dimensions of which are 2-15 millimeters. The greatest secrecy is provided by the fifth level, in which the particles have dimensions equal to 0.8 × 12 mm. The maximum secrecy is the sixth level, at which the particles have dimensions equal to 0.8x4 millimeter.

For reference

Schroeder, whose photo is presented in the article, can be performed in an alternative version. Such a device uses in its work the method of arson, composting and chemical decomposition.

Variety in the field of use

For use in a home or office environment, 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 be located even next to the desk. You can also find such models that are installed on the wastebasket. Repair of shredders will not be necessary if it is properly operated. The most often fail is the office equipment, which is used very often. They are designed for collective exploitation and destroy a large number of documents, providing an average level of secrecy. Archival devices are designed to destroy on an industrial scale a large number of documents, magazines and floppy disks, as well as folders and disks along with internal contents and metal inserts.

Data recovery

Repair of shredders is made by specialists, it is best to entrust this business to professionals. Since in some cases, the technique itself can not be returned to the working state by own strength. Manufacturers emphasize that after data destruction, it may be necessary to restore them. If the elements were not mixed, then the remainders of the document are close to each other. You can restore it even manually. After 1979, US manufacturers added to their devices the possibility of destroying documents by spraying and chemical decomposition. 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 to restore documents. The cost of recovering one sheet that has been cross-processed 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.
