[0002] Ceramic powder is a kind of fine powder material commonly used in the production of ceramic products. It is made of ceramic raw materials through crushing, grinding, screening and other processes, and has the characteristics of fine particles, uniform color and uniform particle size. Ceramic powder is widely used in the fields of ceramic tiles, porcelain, ceramic crafts, etc. To process ceramic powder, vibration motors are usually used as one of the ceramic powder equipment. Vibration motors are a commonly used mechanical equipment that uses its vibration power to vibrate the materials in the ceramic powder processing equipment, thereby achieving the functions of powder screening and grinding.

[0003] The vibration motor is mainly composed of motor, vibrator, bearing, drive device and other components. Its working principle is to drive the vibrator to generate vibration force through the rotation of the motor, and this force will be transmitted to the working device to generate vibration movement. A vibration motor with a reasonable structural design can provide a stable vibration frequency and amplitude to ensure that the ceramic powder can be effectively processed during the processing.

[0004] There are two main applications of vibration motors in ceramic powder equipment. First, it can be used in the powder screening process to separate ceramic powders of different particle sizes through vibration to obtain ceramic powders of the required particle size. Second, vibration motors can also be used in the grinding process of ceramic powders. Through the vibration force, the ceramic powders and the grinding media rub against each other to achieve the purpose of refining the powder particles.
