Grinding is a crucial part of the processing of flame retardant materials, which directly determines the particle size, dispersion and final performance of the material. With its unique grinding principle, the vertical grinding machine has become a powerful tool for achieving ultra-fine flame retardant materials.
The vertical mill "Cell Mill" combines gravity and fluidization technology to work in a grinding chamber in which the material is placed together with the grinding medium. The grinding medium is usually ceramic beads with high hardness and strong wear resistance, such as zirconia beads, etc., which act as "micro tools" in the grinding process. The stirring shaft rotates at high speed under the drive of the motor, which generates strong kinetic energy to drive the grinding medium to do a violent circular motion, so that the media and the material collide frequently, and the material particles are crushed by the impact force; On the other hand, the centrifugal force generated by rotation causes the material and medium to move upwards to form a fluidized state. In this process, the material particles of different particle sizes are stratified due to gravity, the fine particles migrate upward, and the coarse particles fall back to continue to accept grinding, and so on, so as to achieve efficient ultra-fine grinding of materials.
In terms of particle size control, the nano mill can easily break through the micron boundary and achieve ultra-fine grinding below 100 nanometers with its precise design and advanced technology, which provides a particle size guarantee for the high performance of flame retardant materials. In terms of output and energy consumption, the fluidization and gravity collaborative grinding technology adopted by the nano mill greatly improves the grinding efficiency, and the output can be increased several times compared with the traditional equipment under the same energy consumption; From the perspective of environmental protection and quality control, the nano mill adopts a fully enclosed structure and cooperates with an efficient dust removal device to ensure that there is no dust leakage in the production process and achieve clean production. At the same time, its precise grinding control ability makes the product particle size distribution narrow and consistent, reduces the fluctuation of product performance caused by uneven particle size, and lays a solid foundation for the stable production of high-quality flame retardant materials. Whether it is dealing with inorganic flame retardants such as aluminum hydroxide and magnesium hydroxide, or organic flame retardants such as ammonium polyphosphate, melamine cyanurate, etc., the nano mill can accurately adjust the process parameters according to the characteristics of the material to ensure excellent grinding results
