Introduction to plastic recycling and washing line

The characteristics of PE film/agricultural film, PP woven bag/ton bag/baling bag recycling and washing line are that it can effectively remove plastic film containing sediment.

With the continuous development of agricultural technology and the improvement of people's living standards, agricultural film and greenhouse film have been widely used in agricultural technology, bringing huge benefits to the great development of agriculture and the improvement of crop varieties. However, the large-scale application of agricultural film also brings huge problems to land pollution and recycling. In addition, due to the application characteristics of agricultural film, there is a lot of sediment; it also brings huge problems to the recycling process. In view of this situation and the characteristics of agricultural film. Zhangjiagang Kangju Machinery Co., Ltd. has developed a professional agricultural film cleaning, recycling and granulation production line to solve the problems of sediment and water use in agricultural film recycling. At the same time, it solves the technical difficulties of dehydration, drying, granulation and high yield. At present, it has been well applied in China. The specific process route is as follows:

Cleaning process: belt feeding-film crushing-high-speed spiral cleaning-pre-cleaning-low-speed cleaning-film desanding machine-rinsing-film squeezer-silo

Due to the high content of mud and debris (50-60%), there are many difficulties in recycling. The wear problem is very serious, especially the wear of crushing tools and equipment is very large, which seriously affects the output. According to its characteristics, the first pass uses a hydraulic baling and shearing integrated machine to pack the messy ground film, install 150-200MM shears, cut each block 5-7 times, and first carry out magnetic separation through the belt conveyor to select the magnetic metal, and then enter the drum screen. The material is loosened in the drum screen and the mud and sand are initially discharged through the mesh. Then it enters the crushing machine. At this time, the material contains about 10% sediment, which greatly reduces the wear of the crusher and cutters. The crushed material is cleaned by a high-speed spiral and desander, and then enters the beating and washing separator. The material stretches in the water, and the double-axis beating further removes sand and sedimentation. Then it enters the low-speed friction washing for further cleaning, and enters the next level rinsing tank for cleaning and separation. The spiral feeding plastic enters the squeezer. The extruded material is in a semi-plasticized state with a water content of about 7-8%. It is blown into the storage room for natural evaporation of water, and then granulated. Side feeding forced feeding and two-stage filtration and water ring granulation are adopted.
