Abstract
Description
Technical Field
[0001] The invention relates to the technical field of crushing equipment, in particular to a high CTI plastic crusher. Background Art

[0003] Regarding the crushing of products made of PA66 and PBT materials, a crusher is usually used to put the products made of PA66 and PBT materials into the hopper of the crusher. The products made of PA66 and PBT materials in the hopper enter between two crushing rollers, and the two crushing rollers crush the products made of PA66 and PBT materials through the teeth on the circumferential surface; however, when crushed by two crushing rollers, due to the certain toughness of PA66 and PBT materials, the products made of PA66 and PBT materials enter between the two crushing rollers, and some waste products are not crushed. The waste products that are not crushed are transported to the heating tank used to melt PA66 and PBT through pipelines. The waste products that are not crushed are relatively long in size and are easily stuck on the inner wall of the pipeline to form a bridge. The waste products that enter later are easily accumulated on the bridge, causing pipeline blockage and affecting the normal transportation of the waste products. Summary of the invention
