Production process of recycled tread rubber powder

Abstract

The invention discloses a production process of reclaimed tread rubber powder. Grinding and magnetic separation equipment comprises a mixture conveyor belt, a rubber particle discharge hopper, a first full magnetic roller, a driven roller, a steel wire separation conveyor belt, a steel wire recovery conveyor belt, a steel wire discharge hopper, a rubber particle conveyor belt, a rubber discharge hopper, a circulating conveyor belt, a second full magnetic roller, a baffle, a rubber coarse grinder, a first vibrating screen, a first conveyor belt, a recovery conveyor belt, a rubber powder grinder, a second conveyor belt, a second vibrating screen and an iron-containing rubber particle receiving hopper. A grinding and magnetic separation process comprises the following steps: grinding and screening a blocky tire via a coarse grinder to obtain coarse particles, obtaining pure coarse rubber particles and recovered steel wires through first magnetic separation and second magnetic separation and grinding the pure coarse rubber particles via the grinder and then screening the powder, thus obtaining the rubber powder. The production process has the beneficial effects that the iron wires can be effectively separated; wear of the equipment can be reduced; and the service life of the equipment is long.

Description

technical field [0001] The invention relates to a production process of regenerated tread rubber powder. Background technique [0002] At present, the production process of recycled tread rubber powder includes separating the waste tires from the mouth, cutting them into strips, cutting them into pieces, and then directly crushing the cut tires into fine powders of 30-32 mesh, and then magnetically separating the fine powders. Get Iron Shavings and Rubber Powder. 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 completely remove during 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 devoted to developing a kind of production technology of the regenerated tread rubber powder that can effectively sepa...
