Shredders are slow-running crushing machines (approx. up to 80 revolutions per minute) and are used to crush unsorted and bulky waste (plastic, rubber, tyres, wood, paper, municipal waste, baling from presses (so-called lumps), etc.).
The Terier company produces single-shaft crushers, double-shaft crushers, and four-shaft crushers. There is a detailed description for the individual categories.
