Why choose water ring granulating?

String granulating line components

➢ Extruder LB Machinery offers single screw extruder for the PE or PPR strand cutting pelltizing as well as twin screw extruder for PVC strand pelletizing line. We pull off the raw material into the feeder and extrude plasticizing stand.

➢ Water Bath Cooling In the water bath, the raw material strand was cooled and moving forward together with the flowing water. During the forward movement, the plasticizing strand harden and cooling.

➢ Air Knief Drying Getting through the water bath cooling, the plasticizing strand are dried by the air knief. The blowing wind takes away the excess moisture that is the preparation for the pelletizing.

➢ Rotor of Pelletizer Our pelletizer utilize the helical blades of bolt-on blades. The blade runs at a high speed continuously to cut out the uniform-sized granules.

➢ Vibrating Sieve The granules out the pelletizer go through the vibrating sieve. Under the high frequency vibrating, the granules can be figure out into big, medium and small. Through processing, we can get particles of uniform size.

Optional

➢ Screen Changer It is optional. The screen changer is used to filter the impurities. If the granulated material is purity, the screen changer is unnecessary.

➢ Equipment Color We offer customized equipment color. Plenty of machine color is available.

Water ring granulating process

Totally understanding the strand pelletizing process is conducive to figuring out whether the process fits the production condition or not. As a universal granulating method, the strand pelletizing has following advantages:

➢  Low equipment cost ➢ Easy maintenance ➢ Suitable for most of the materials

Disadvantages are listed in comparison with other pelletizing methods such as water ring or under water pelletizing:

➢ Relatively low automation grad ➢ High energy consumption ➢ More Labor cost needed
