Abstract
The invention discloses a method for preparing regenerated rubber powder. Equipment for crushing and magnetic separation comprises a mixture conveying belt, a rubber granule discharging hopper, a first fully-magnetic roller, a driven roller, a steel wire separating and conveying belt, a steel wire recovering and conveying belt, a steel wire discharging hopper, a rubber granule conveying belt, a rubber discharging hopper, a circulatory conveying belt, a second fully-magnetic roller, a baffle, a rubber coarse-crushing crushing machine, a first vibrating sieve, a first conveying belt, a recovery conveying belt, a rubber powder crushing machine, a second conveying belt, a second vibrating sieve, a ferriferous rubber granule receiving hopper and an iron powder collection box. A process for crushing and magnetic separation comprises the steps of crushing lumpy tires by a coarse crusher, sieving, so as to obtain coarse granules, carrying out first-time magnetic separation and second-time magnetic separation, so as to obtain pure coarse rubber granules and recovered steel wires, crushing the pure coarse rubber granules by a crushing machine, and then, sieving, thereby obtaining rubber powder. According to the method, iron wires can be effectively separated, so that the wear to the equipment is reduced, and the service life of the equipment is long.
Description
technical field [0001] The invention relates to a preparation method of regenerated rubber powder. Background technique [0002] At present, the preparation method of regenerated rubber powder includes separating the waste tires from the mouth ring, cutting into strips and dicing, and then directly crushing the diced tires into fine powders of 30-32 meshes, and then magnetically separating the fine powders to obtain 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 preparation method that can not only effectively separate iron wire, but also reduce the wear and tea...
