Abstract

The present invention is a method for producing crushed elastomer consisting of steps for delivering The liquid is sprayed from one or more nozzles onto a flexible, rubber-like material that moves in The cross-sectional direction is at least partially as viewed from the discharge direction of at least one nozzle. In such a method according to the invention a liquid is sprayed directly onto a flexible rubber-like material. A pressure of 650-1350 bar and a flexible rubber-like material are moved in relation to the At least one nozzle in such a manner that the first stage is adapted for surface decomposition. of elastomeric materials. elastomeric materials have a feed advance rate of First at 10 to 20 mm/s at the point of impact the liquid is sprayed in a direction opposite to the direction released and in the second phase after the surface of the material is broken down, it is said that the material has similar elasticity. The rubber has a second pre-fill rate that is reduced by 3565% compared to the feed rate. Moreover, this invention is a tool for producing crushed elastomers.
