Scientific novelty

The extraction grab allows for the extraction of raw materials in the form of peat fibrous material without disturbing its structure, which provides the opportunity to fully utilize the beneficial properties of the upper layer of peat deposits.

Advantages

The device for extracting fibrous material with side cutting pairs is equipped with a bayonet that allows processing a portion of fibrous material across the entire side surface and, together with the knives, implements inclined fiber cutting when the jaws close. This eliminates the possibility of untreated side zones in the material portion and ensures an even cut along the entire contour of the side surface.

Commercial implementation

It can be used both in the development of mineral deposits to obtain a by-product, and for the targeted extraction of the fibrous layer of peat deposits with subsequent regeneration within 2 years. Natural fibrous raw materials are used for the production of filter elements for the treatment of surface runoff from mining operations.
