Types of High-Speed Shredders

A shredder machine, also known as a shredder, is a large-scale industrial crushing equipment primarily used to reduce solid waste into smaller pieces. An essential component of waste recycling and management systems, Shredder machines have a wide range of applications, from cardboard shredders to high-speed shredders. High-speed shredders offer the benefit of high throughput for various materials and are ideal for use in large recycling facilities and waste management operations.

According to reports, the global shredder machines market was valued at USD 168.38 million in 2022 and is expected to reach USD 239.00 million by 2028, with a CAGR of 6.38 percent during 2022-2028. This indicates that the types of high-speed shredders continue to grow, as do their applications.

Broadly speaking, high-speed shredders can be categorized into the following three main types:

• High-Speed Jaw Crushers:

  A high-speed jaw shredder operates by using immense plates to crush the material. It creates rapid back-and-forth motions to pulverize the waste. High-speed jaw crushers can process bulky waste efficiently and are suitable for diverse applications. They have relatively lower maintenance requirements compared to other types of high-speed shredders.

• High-Speed Impact Shredder Machines:

  High-speed impact shredders function by fracturing the waste through high-speed rotational movements. They are suitable for processing rigid to medium-hard materials, such as plastic bottles, containers, and film. Furthermore, impact shredders have the advantage of being easily configured to obtain various output sizes to suit specific recycling requirements.

  The design of high-speed impact shredders also allows for rapid separation and extraction of diverse materials. Many of them can be integrated with additional separation technologies, such as air classification, magnetic separation, and optical sorting, to achieve a more thorough purification of the final recycled product.

• High-Speed Hammer Mill Shredders:

  Hammer mills differ from impact shredders in that they use hammers mounted on a rotating disc to smash the material. High-speed hammer mills operate at high speeds to crush, shred and pulverize various types of materials, such as plastic, fiber, film, wood, and paper. They are also suitable for processing light and soft materials. The design is compact, and the machines can be installed in different facilities to save space.

In addition to the ones mentioned above, other types of high-speed shredders include paddle mixers and granulators. Granulators are often used at the end of a product's life cycle to produce smaller pellet-like forms. They are easier to handle and can be reused to create new products.
