PA PP Pulverizer

For disc-type pulverizing of low-melting-point plastics such as PA and PP,Maoyue has enhanced the traditional water-cooling system by incorporating a low-temperature cold air unit,creating a combined water-and-air cooling solution.During high-speed operation,the disc temperature can rise rapidly,causing material softening,adhesion to blades,and issues such as stringing or agglomeration,which can affect powder quality and continuous operation.By continuously supplying low-temperature,high-velocity cold air to the grinding chamber and disc area,the system effectively removes heat generated during processing,significantly reducing the temperature of the disc and chamber,minimizing the risk of blade adhesion at the source,and enhancing operational stability.
In addition,the pulverizer features specially optimized disc teeth for low-melting-point materials,using a short-and-thick tooth design.Compared with traditional long,thin,or standard tooth profiles, this design shortens the cutting friction path and reduces contact area, thereby lowering heat accumulation per unit time and ensuring a more gradual and controllable rise in chamber temperature.
With these two core improvements,the machine demonstrates significant advantages when processing PA,PP,and related modified materials: most operations can be carried out without the need for liquid nitrogen deep-cooling;blade adhesion,material clumping,and stringing are substantially reduced;powder particle size distribution is more uniform,ensuring consistent product quality;continuous operation is enhanced,and downtime for cleaning is greatly minimized;additionally,costs related to liquid nitrogen procurement,storage,and safety management are significantly reduced.
This optimized solution not only improves equipment reliability and adaptability to materials but also enables higher production efficiency and lower operational costs,achieving a dual optimization of equipment performance and economic benefits.
