Production device of rubber powder

Abstract

The invention discloses a production device of rubber powder. Tires which are cut into blocks by coarse crushing are firstly ground into coarse particles by a rubber coarse crusher, and then magnetic separation is carried out on the coarse particles. Compared with an existing device which directly grinds the rubber into powder before magnetic separation, the production device of the rubber powder is capable of grinding a steel wire which is incompletely ground into powder, so that the magnetic separation efficiency is high, and iron removal rate is high. Furthermore, before reaching the rubber crusher, the coarse particles are subjected to magnetic separation through an all-magnetic drum, so that the iron-containing rubber particles are thoroughly removed and can return to the rubber coarse crusher to be crushed. After the magnetic separation is carried out by the all-magnetic drum for twice, the steel wire removal rate reaches up to more than 99%. After the rubber particles are ground into the rubber powder in the next step, little iron powder in the rubber powder is removed by an iron powder collection box, so that the content of the iron powder in the finished rubber powder product is greatly reduced, and the production efficiency is high. An elastic part in a second movable screen is replaced by a swing type structure formed by a swing arm and a portal frame, so that the screening efficiency is high, and the service life is greatly prolonged.

Description

technical field [0001] The invention relates to a production equipment of rubber powder. Background technique [0002] At present, the process of using waste tires to produce rubber powder includes separating the waste tires from the ring, cutting them into strips and dicing, and then directly crushing the diced tires into fine powders of 30-32 meshes, and then passing the fine powders through magnetic Iron powder and rubber powder are selected. In this way, since the iron wire is directly crushed into iron powder, on the one hand, the wear and tear on the equipment is great; on the other hand, the iron powder is not easy to be completely removed in the magnetic separation, resulting in a large content of iron powder in the final product, which affects the quality of the final regenerated rubber. [0003] Secondly, at present, rubber particles are generally realized by vibrating screens during screening. Current vibrating screens, such as Chinese patents CN202061199U and CN...

Problems solved by technology

In this way, since the iron wire is directly crushed into iron powder, on the one hand, the wear and tear on the equipment is great; on the other hand, the iron powder is not easy to be completely removed in the magnetic separation, resulting in a large content of iron powder in the final product, which affects the quality of the final regenerated rubber

[0003] Secondly, at present, rubber particles are generally realized by vibrating screens during screening. Current vibrating screens, such as Chinese patents CN202061199U and CN202539070U, are mainly composed of a frame, a screening motor (or motor), a screen box and a screen mesh. The screen box is fixed on the top of the frame, and the two are connected by an elastic support, so there is a problem that after a period of use, the elastic support needs to be replaced, and the elastic support has a short service life
