The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment; technical scheme in the utility model embodiment is carried out to clear, complete description; obvious described embodiment is only a part of embodiment of the present utility model; not whole embodiment; embodiment based in the utility model; those of ordinary skills are not paying the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment
As Figure 1-3, the pan grinder device that the utility model provides, comprises upper millstone 1, lower millstone 2 and mine feeding bucket 3, and described lower millstone 2 is fixed in frame 4, and the upper surface circle centre position of lower millstone 2 is provided with square blind hole 21;
The lower surface circle centre position of described upper millstone 1 is provided with oval-shaped groove 11, and oval-shaped groove 11 centers offer and the adaptive bearing installing blind 12 of square blind hole 21, by embedded bearing, drives upper millstone 1 to rotate;
The center line two ends of oval-shaped groove 11 are respectively equipped with rough grain feed port 13 and the thin ore particle feed port 14 being connected with mine feeding bucket.
Further, the edge of described upper millstone 1 is gear-like, by motor 23 driving pinions 24, and then drives upper millstone 1 to rotate by the gear wheel 25 on upper millstone.
Further, the lower surface of described upper millstone 1 comprises outside circle 15 and root circle 16, circle centre position be provided with take the center of circle as summit outward extending a plurality of arc tongues 17, the nock of described arc tongue 17 is shaped as V-type, every adjacent two tongues are equidistant wide.
Further, the upper surface of described lower millstone 2 is provided with and take the center of circle a plurality of arc grooves 22 that with the arc tongue 17 of upper millstone 1 match outward extending as summit.
Further, the degree of depth of described arc groove 22 is no more than 7mm.
