Description

technical field [0001] The invention provides an elastic body fine crushing combination device capable of adding auxiliary materials before and after fine crushing, and capable of stably feeding materials and its configuration method, and relates to the technical category of the process combination of elastomer material fine crushing equipment or the configuration method of a complete set of equipment for the whole process. Background technique [0002] Waste elastomer materials are regenerated through the process of fine crushing, which can not only avoid waste gas and waste water pollution caused by the high-temperature regeneration process, but also the obtained materials do not have the toxic and foul smell of traditional reclaimed rubber; but the current implementation of fine crushing of elastomer materials The integrated combination of equipment also has defects at runtime. Specifically, there are mainly: [0003] 1. In order to obtain elastomer powder with high fine ...

AI Technical Summary

Problems solved by technology

[0003] 1. In order to obtain elastomer powder with high fine powder content, the normal temperature fine crushing process is usually to add an appropriate amount of crushing aid to the elastomer coarse-grained material to be fed into the fine grinder, and because the current integrated combination equipment does not have a corresponding The airtight implementation device, causing the auxiliary materials to pollute the production environment;

[0004] 2. The current integrated combination equipment is not equipped with a corresponding airtight device for adding crushing aids, and without adding crushing aids, the elastomer material is finely pulverized at room temperature. The material that can pass through the 90-mesh sieve in the fine pulverizer will never exceed 40%. Usually, the material that can pass through the 90-mesh sieve in the material processed by the grinding wheel fine pulverizer will never exceed 50%. Among the materials processed by the pulverizer, the materials that can pass through the 90-mesh sieve are only between 5 and 10%; but the coarser elastomer powder that does not pass the 90-mesh sieve, because there is obvious old and new rubber between the coarse powder and the new rubber. The interface is less able to form a uniform phase with the new rubber, so their performance is poor when mixed in the new material;

[0005] 3. In the current so-called vulcanized rubber fine powder complete set or integrated combination equipment unit, each single fine pulverizer is connected in parallel to form a group, and then connected in series in the pulverization integrated combination unit. The imported uplink combination unit of the fine pulverizer unit In the 5-30 mesh coarse material bin, the outlet of the fine crushing unit passes through the cyclone separator, and then it is sent to the rubber powder classifier or screening machine, and the separated fine material enters the storage bin and the coarse material returns to the coarse material bin; Such a combination of equipment and process configuration, because the particle size of the incoming material and the content of the crushing aid in the feed cannot be kept constant, the coarse material in the finely crushed material increases, and the return of the coarse powder after sieving increases, and finally the 5 The feed flow rate of ~30 mesh coarse material decreases or stops, which causes the production capacity of the whole unit to fluctuate;

[0006] 4. After the elastomer material is finely crushed to 90 meshes or less, the specific surface area and flyability of the material increase rapidly. Compared with the traditional reclaimed rubber, the ultra-fine elastomer rubber powder product is more difficult to mix and fuse with the rubber material. Defects such as slowness and dust flying; because there is no requirement in the industry for ultra-fine elastomer rubber powder products to implement quality indicators such as fineness and no noise, and there is no such relevant enterprise, industry, and national standards at present, so the current fine Complete sets of rubber powder or integrated combination equipment are not equipped with mechanical devices that can implement dust removal and plasticization processes such as adding and mixing auxiliary materials
