What is Schroeder: purpose and principle of work

Schroeder (from English. Shred -Grind)-this is a mechanical or electrical device designed to grind paper documents, plastic cards, CD/DVDs and other materials in small parts that make it difficult to restore information.

The principle of operation is based on the passage of paper between knives or shafts, which cut the sheets along, across or in the cross -drawn direction. The result is paper chips or confetti — depending on the type of cutting.

By type of cutting

• Longitudinal cutting: paper cut into long strips with a width of 2 to 12 mm. This is the easiest and most affordable option. Suitable for the destruction of general documents without critical information.
• Transverse-proper cutting (Cross Cut): Sheets are cut along and across, turning into small rectangular pieces. Provides a higher level of security.
• Micro cutter (Micro Cut): The paper turns into tiny fragments in size about 2 × 10 mm. It is used to destroy confidential data, for example, in legal or financial organizations.
• Nanoism (Nano Cut): The highest level of security. Particles are so small that restoration is impossible even with special equipment.

By the type of carriers

• Only paper. Standard models designed for cutting A4 or A3 format sheets.
• Paper + plastic cards. Equipped with more durable knives.
• Multifunctional (universal). They can cut paper, disks, CD/DVD, cards and even paper clips.

By performance

• Personal shreders. Up to 10 sheets per run, a small volume of the basket (up to 20 liters).

• Industrial. Up to several hundred sheets at the same time, continuous work, powerful motors, capacity of up to 200 liters and higher.

• P-1: stripes up to 12 mm. Suitable for public data.
• P-2: stripes up to 6 mm.
• P-3: particles up to 320 mm². Commercial documentation.
• P-4: particles up to 160 mm². Confidential documents.
• P-5: particles up to 30 mm². Very important documents.
• P-6: particles up to 10 mm². Critically important information.
• P-7: particles up to 5 mm². Secret and state data.
