The underwater granulator is similar to the air flow granulator and the water jet granulator. The Beijing Zhongsu Lianfa Plastic Machinery Science Research Institute is headquartered in Beijing. The after-sales service system is distributed in Beijing, Shanghai, and Guangzhou. It is mainly engaged in plastic modification formulas. R&D independent development technology is highly targeted. The equipment part mainly covers: plastic granulators, single and twin screw plastic extruders, plastic film blowing machines, bag making machines, printing machines, coating machines, tape slitting machines, and strapping machines. In terms of modified formulas, plastic formulas such as plastic wrap and degradation film have been developed based on alloy materials. The difference is that it has a smooth flow of water flowing through the mold surface and in direct contact with the mold surface. The size of the pelletizing chamber is just enough to allow the pelletizing knife to rotate freely across the die surface without limiting the water flow temperature. The molten polymer is extruded from the die and cut into pellets by a rotating knife. The pellets are taken out of the pelletizing chamber by temperature-regulated water and enter the centrifugal dryer. The water is drained back to the storage tank to be cooled and recycled to use the pellets to remove the moisture through a centrifugal dryer. The strip production line is inexpensive, easy to operate and easy to clean. This has its advantages for color compounding because the changeover between two batches of different color materials requires a thorough cleaning of the equipment. However, the disadvantage of the strip making method is that the cooling section requires space and its length is determined according to the temperature requirements of the polymer.
