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

Abstract

The invention discloses a device for circularly grinding and deironing reclaimed rubber powder. The device has the beneficial effects that firstly, tires coarsely ground into blocks are firstly ground into coarser particles by a rubber coarse grinder, and then magnetic separation is carried out. Compared with existing devices for directly grinding rubber into powder and then carrying out magnetic separation, the device has the advantages that steel wires are not completely ground into iron powder, the magnetic separation efficiency is high, and the iron removal rate is high; secondly, the coarse particles are subjected to magnetic separation in full-magnetic rollers before reaching a rubber powder grinder, the rubber particles containing iron are completely removed, and the rubber containing iron can return to the rubber coarse grinder to be ground. Therefore, through two-time magnetic separation in the full-magnetic rollers, the steel wire removal rate can be more than 99%; after the rubber particles enter the next procedure of finely grinding the rubber particles into rubber powder to be ground, little iron powder in the rubber powder is removed via an iron powder collecting box. The device greatly reduces the content of iron powder in the finished rubber powder product and has high production efficiency.

Description

technical field [0001] The invention relates to a reclaimed rubber powder circulation crushing iron removal device. 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] Therefore those skilled in the art are devoting themselves to finding a reclaimed rubber iron removal device that can improve the removal rate o...
