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

Deironing apparatus is pulverized in a kind of ground rubber circulation
Technical field
The present invention relates to a kind of ground rubber circulation and pulverize deironing apparatus.
Background technology
At present, the technique of utilizing junked tire to produce rubber rubber powder comprises carries out the separation of mouth circle by junked tire, and slitting, stripping and slicing, be then directly ground into the tire after stripping and slicing 30-32 object fine powder, then this fine powder is obtained to iron end and rubber powder through magnetic separation.Like this, because iron wire is directly ground into iron end, on the one hand large to the wearing and tearing of equipment, on the other hand, iron end is difficult for removing completely in magnetic separation, causes in final product iron end content large, affects the quality of last reclaimed rubber.
Therefore those skilled in the art are devoted to find a kind of deironing apparatus of the reclaimed rubber that the clearance rate at iron end in rubber powder can be improved.
