Description

Technical Field

[0001] The present invention relates to the technical field of reclaimed rubber production, and in particular to a natural reclaimed rubber production device and method. Background Art

[0002] Reclaimed rubber is rubber processed from vulcanized scrap materials in rubber product production, with a certain plasticity and the ability to be reused. Abbreviated as reclaimed rubber, it is divided into types such as outer tire type, inner tire type, and rubber shoe type according to the used waste rubber. Reclaimed rubber can partially replace raw rubber in rubber products, saving raw rubber and carbon black, and is also beneficial to improving processing performance and certain properties of rubber products.

[0003] In the process of processing rubber particles into reclaimed rubber, a certain amount of activator and softener need to be added to the rubber particles to ensure the forming effect after desulfurization treatment. The existing reclaimed rubber production devices often adopt the method of manual addition when adding the activator and softener. This method usually has great uncertainty, and the addition amounts of the activator and softener cannot be accurately controlled, resulting in over-addition or insufficient addition of the activator and softener, leading to waste of additives or affecting the production quality of reclaimed rubber.
