1. High particle quality：
   • Beautiful and uniform appearanceThe cut particles have regular shapes and good appearance quality. For example, in HDPE pipe material water ring cutting, the particles are comparable to new materials and can meet the production needs with high requirements for product appearance.
   • Not easy to bondThe particles are not easily adhered to each other, ensuring their independence and good fluidity, which facilitates subsequent storage, transportation, and use.
2. high yield：
   • Cutting blade rotates at high speedThe machine head template has a large number of holes, and the cutting blade can rotate at high speed, which can quickly cut the extruded melt into particles, greatly improving production efficiency. For example, using a screw with a diameter of 480mm, a speed of 110r/min, and an extruder with a motor power of 2200kW to manufacture polyethylene pellets, the maximum production rate can reach 15t/h.
3. Good operating environment：
   • Closed operationThe entire cutting process is carried out in a relatively enclosed environment, and the cut particles are transported by water to the designated location, reducing the possibility of dust and debris mixing in, ensuring the cleanliness of the production environment, and also reducing the impact on the health of operators.
   • Operation without noiseWater acts as a sound barrier during the grain cutting process, effectively reducing the emission of noise and providing a relatively quiet working environment for operators.
4. Compact equipment with small footprintThe integration of cutting tools and the coaxial arrangement of water jackets around the mouth template make the equipment structure compact, occupy a small area, and suitable for use in production sites with limited space, saving space costs.
5. Good adaptability to materials：
   • Suitable for various materialsSuitable for granulation of various materials such as EVA hot melt adhesive, TPU elastomer, cable material, etc., it can meet the production needs of different industries and products.
   • reduce wearWhen cutting unfilled materials into pellets, a thin layer of polymer will form on the hot mouth template, which can effectively reduce the wear of cutting tools and mouth templates, extend the service life of equipment, and reduce equipment maintenance costs.

Disadvantages of water ring hot cutting machine：

1. The ancillary equipment is huge and complex：
   • Multiple system componentsThe water ring hot cutting machine is usually composed of a water ring granulator head, a warm water circulation system, a separation system, a screening system, and other parts, with many auxiliary equipment and a complex structure.
   • Difficulty in maintenanceThe large auxiliary equipment increases the difficulty and cost of equipment maintenance, requiring professional technicians to perform regular maintenance and upkeep to ensure the normal operation of the equipment.
2. High energy consumption：
   • Maintain the temperature of the machine headDue to the contact between the machine head and warm water, a large amount of heat is required to maintain the temperature of the machine head during operation, which increases energy consumption and production costs.
3. High requirements for operating conditions：
   • The gap between the cutting blade and the template is smallThe gap between the rotating cutter and the porous template surface is small, requiring high operating conditions. If the operation is improper, such as inaccurate installation of the cutting blade, unstable material melt pressure, etc., it is easy to cause blockage of the mold hole, affecting the continuity and stability of production.
4. Strict requirements for extrusion process：
   • High requirements for parameter controlHigh requirements have been put forward for the temperature of the extruder, extrusion speed, temperature of the connecting body, melt pressure, temperature of the discharge template, number of holes in the discharge template, temperature and pressure of the cooling water, as well as the uniformity of the raw material mixing ratio. Only when these conditions are suitable can the normal cutting and particle quality of the water ring granulator be guaranteed.
