The colloid grinder of the utility model, as shown in figure 1, comprises a driving motor, a rotating shaft 1 and a grinding head, wherein the grinding head comprises the rotor and the stator.

The grinding head of the colloid mill of the present invention, as shown in fig. 1 to 4, comprises a rotor 2 mounted on a rotating shaft 1 and a stator 3 disposed outside the rotor 2, and the rotor 2 is provided with elongated rotor grinding teeth 4 on a circumferential surface 7 thereof. A groove 5 is formed between adjacent rotor grinding teeth 4, each rotor grinding tooth comprises a first inclined surface a and a second inclined surface b, and the first inclined surface a and the second inclined surface b form a rotor grinding tooth tip 41; the circumferential surface 8 of the stator 3 is provided with elongated stator grinding teeth 6, which comprise a first bevel a and a second bevel b, which form a stator grinding tooth tip 61.

That is, the rotor grinding teeth and the stator grinding teeth are inclined triangles in cross section, and the projection of the first slope a on the cross section is shorter than the projection of the second section b on the interface, so that the grinding tooth tips 41 and the stator grinding tooth tips 61 are clearly inclined toward one side. Obviously, in the above-described triangle, as shown in fig. 7, the angle β between the second slope b and the circumferential surface is acute.

The rotor grinding teeth 41 face the stator grinding teeth 61 in the direction of inclination, and the rotor 2 rotates in the direction opposite to the direction of inclination of the rotor grinding teeth 41.

For example, if the rotor grinding tooth tips 41 are directed clockwise in fig. 4 and 5, the stator grinding tooth tips 61 are counterclockwise and the direction of rotation of the rotor 2 is counterclockwise.
