[0003] The current existing patent (Announcement No.: CN208407186U) discloses a basket-type fine grinding machine. This device includes a base, a grinding barrel is arranged on the upper plate surface of the base, and a grinding head is arranged just above the grinding barrel. The grinding head relies on a lifting assembly to make a vertical lifting motion relative to the grinding barrel; the grinding head includes a rotating shaft, a power motor and a basket body, an extension shaft coaxially extending downward from the basket body and a dispersion disk fixed on the extension shaft, the dispersion disk is in the shape of a wheel sheet and a pump blade-shaped stirring tooth for dispersing and stirring is arranged at the rim; a sealing cover is also coaxially sleeved outside the rotating shaft, and a through hole is provided on the sealing cover, one end of the negative pressure tube is connected to the barrel cavity of the grinding barrel through the through hole, and the other end of the negative pressure tube is connected to an external negative pressure device. The utility model can achieve the purpose of fine stirring of medium and low viscosity materials in a short time, and is particularly suitable for efficient mixing, homogenization, dispersion and grinding operations of micron-level or even nano-level materials.
