Description

Technical Field

[0001] The utility model relates to the field of rubber production, in particular to a raw material crushing device for rubber production. Background Art

[0002] Rubber refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature and can produce large deformation under very small external force. It can return to its original state after the external force is removed. The rubber industry is one of the important basic industries of the national economy. It not only provides people with daily necessities, medical and other light industrial rubber products that are indispensable in daily life, but also provides various rubber production equipment or rubber parts to heavy industries and emerging industries such as mining, transportation, construction, machinery, and electronics. In the process of rubber production and processing, in order to improve production efficiency, the raw materials are crushed, and a crushing device is needed for crushing.

[0003] The existing device usually includes a feed port, a crushing chamber, a blade, a screen and a discharge port. When working, the rubber raw material enters the crushing chamber from the feed port, is cut and ground by the high-speed rotating blade, and the crushed rubber particles are screened by the screen. The particles reaching the required particle size are discharged from the discharge port for subsequent rubber processing steps. However, crushing the rubber raw material will generate dust, which pollutes the environment and dust removal measures need to be taken. To this end, we propose a raw material crushing device for rubber production to solve the above problems. Utility Model Content
