Pengyi Sanding Machine | Read This Article To Know More About Ceramic Powder Grinding

The rapid development of 5G communications, automotive electronics, semiconductors and other industries has also driven the development of the ceramic industry.

Whether it is electronic ceramics, microwave ceramics or ceramic substrate, the raw material preparation process, it is necessary to grind the powder. From a larger perspective, most powder materials need to be ground before entering the next process, such as lithium battery cathode materials, coatings, and even the food industry.

Whether the material is fully mixed and ground in place has a significant impact on the performance of ceramic powder, so it is necessary to pay attention to the mixing and grinding of the material. If you want to obtain a good performance of the grinding material, you need a suitable grinding equipment and the corresponding grinding process. Sand mill is the most suitable equipment to deal with ceramic powder grinding.

Large Flow High Efficient Sand Mill

◎ The mixing shaft with grinding disc is installed horizontally in the grinding cylinder.

◎ The grinding bead in the grinding cylinder is activated by a rotating grinding disc.

◎ The material flows axially from the feed to the discharge, and is struck by grinding beads during the process.

◎ The material is separated from the grinding bead at the exit.

The energy density and flow rate are moderate, the bead filling amount is large, and the particles can be ground to the micron range.

Pin Type Nano Sand Mill

◎ Rod pin type sand mill grinding cylinder is short, the top of the rod pin is close to the wall of the grinding cylinder, and the bead line speed is large.

◎ The cylindrical gap separator has a large volume, occupying nearly two-thirds of the grinding shaft cavity.

◎ The power of the main motor is large, about 3 times that of the same volume disk sander.

The material is ground to sub-micron or nanometer level by means of large flow cycle grinding.

The grinding method of the sander

Sand mill is an effective wet grinding and dispersing equipment. The working principle is that the slurry enters the closed grinding chamber and contacts with the high-speed rotating grinding medium, and the solid particles in the material and the grinding medium collide, friction and shear each other, thus dispersing, crushing, grinding, homogenizing and depolymerizing the slurry flowing through the chamber.

The consistency of ceramic powder is the current technical difficulty in the production of 5G ceramic filter, and the consistency of the powder determines the subsequent production process and affects the performance of the filter. In the process of ceramic powder grinding, the Peng wing sand mill plays a very important role. Through the cycle of mixed pre-dispersion, coarse grinding and fine grinding, the densification, electrical properties and reliability of ceramic powder are improved, and the problem of uneven density caused by large particles, hard agglomeration or hollow particles in the powder is solved.
