从各个地方收集到的废旧塑料，需要经过分类清洗才能造粒使用。废塑料品种太

Waste plastics collected from various places need to be sorted and washed before they can be granulated. There are too many types of waste plastics, different melting temperatures, can not be sent to the extruder for granulation, and other impurities need to be sorted out. To this end, we have done hundreds of experiments, from sorting, removing impurities to the purification process have done a lot of research and development, we first use wind to sort according to different uses of plastic products, and then use the magnetic field to filter. The cleaning process is to first separate paper scraps, weeds, food and plastic by wind, then use a round broom to physically remove, and finally use a small amount of circulating water for cleaning. It can be used after drying. In doing so, it is reduced by labor, the workload is reduced, and the equipment investment is greatly reduced, which is beneficial to popularization.

Waste plastics collected from various locations need to be sorted and cleaned before granulation can be used. There are too many varieties of waste plastic, different melting temperatures, can not be fed into the extruder at the same time for granulation, there are other impurities to be picked out. To this end, we have done hundreds of experiments, from sorting, removal of impurities to purification process have done a lot of research and development work, we according to the different uses of plastic products first with wind sorting, and then using magnetic fields for screening. The process of cleaning is to separate the confetti, weeds, food and plastic by wind, then physically remove them using a round crucin, and finally with a small amount of recycled water. After drying, it can be used. This has been done with less labour, less work, and a significant decline in equipment investment is conducive to universal ization.

The waste plastics collected from various places can only be used by granulation after classified cleaning. There are too many kinds of waste plastics and different melting temperatures, so they can not be sent to the extruder for granulation at the same time. In addition, other impurities need to be picked out. For this reason, we have done hundreds of experiments, and have done a lot of research and development work from sorting, impurity removal to purification process. According to different uses of plastic products, we first use wind to sort, and then use magnetic field to screen. The cleaning process is to separate the paper scraps, weeds, food and plastic by the wind first, then use the circular broom for physical removal, and finally use a small amount of circulating water for cleaning. After drying, it can be used. In this way, the use of labor is reduced, the workload is also reduced, and the equipment investment is greatly reduced, which is conducive to popularization.
