Abstract

The utility model relates to a ball-shaped mill which can mill materials into thin and uniform granules. The utility model changes plane milling slices or conical milling slices of the existing powder and milk milling machine into the ball shapes, and besides, an annular tooth is added on the outer circumference. Gaps among the ball-shaped milling slices can be easily adjusted into conformity, and the ball-shaped teeth prevent the material granules which are not milled into thin granules falling out from positions between milling slices. The materials milled by ball-shaped mill are thin and uniform.

Description

Pot mill

It is sphere that the utility model relates to a kind of abrasive disc working face, and the teeth groove of abrasive disc is less than the material abrasive dust machinery on the external cylindrical surface of abrasive disc.

The present abrasive dust machinery of producing, be metal abrasive disc or emery wheel abrasive disc all be do tapered, also there is minority make the plane, the teeth groove of metal abrasive disc is on the external cylindrical surface of abrasive disc, the gap of each side just is not easy to adjust to unanimity between the sound abrasive disc, and the coarse granule of material will big direction drop out from the gap.Even each side is transferred in the gap equally size, because the teeth groove of abrasive disc is on external cylindrical surface, thick material of material still can drop out from teeth groove, so abrasive dust is very inhomogeneous.

In order to address this problem, normally many repeatedly mills several times.The DM150 type Multifunctional mill pulp grinder that the multi-functional machine for grinding and paste of DM-WE150 type that the hand strand grinding machine that agricultural machinery factory, county, Chongqing, Sichuan Province produces, Shishou City, Hubei Province powder technology Co., Ltd produce and Shishou City Agricultural and Animal Husbandry Machinery Plant, Hubei Prov. produce all is taper abrasive discs, is difficult to once levigate.In operation instructions, all advise the many repeatedly mills of user several times, reach the fineness that needs.Be unfavorable for like this increasing work efficiency with energy-conservation.In addition, gapped between the material-feeding plugboard of DM--WE150 and two kinds of flour mills of DM150 type and body, the hopper, when defibrination, adding water can flow out outside the machine, the spring of abrasive disc adjusting device is with in plane bearing is installed in the body that can contact with material, and material particles can be invaded bearing, accelerates bearing wear, water can be invaded bearing and spring during defibrination, Yin Qi Rust erosion.

The purpose of this utility model is that a kind of improved materials crusher tool will be provided, and a powder delivery of its energy is even, and the interpolation water of material can not flow out outside the machine, and the spring of abrasive disc governor motion and bearing and material are isolated, and can prolong the service life of bearing and governor motion.

A kind of pot mill, two abrasive discs are installed in respectively on internal body and the rotor, it above the body hopper, be material-feeding plugboard between hopper and the body, it on the cover of body front the adjusting device of regulating two refining plate intervals, the roll flute tooth top on two sides that it is characterized in that two abrasive discs is in the sphere of equal radii, on the maximum gauge of abrasive disc sphere, one circle and the contour annular tooth of roll flute arranged, material-feeding plugboard a rubber blanket respectively arranged up and down, adorning the compression spring that is enclosed within on the main shaft in the endoporus of rotor, the thrust bearing between adjusting handle and the rotor is contained in the centre bore of cover, change in and cover between sealing ring is arranged.Pot mill according to claim 1, the roll flute tooth top that it is characterized in that the two sides of two abrasive discs are in two spheres of equal radii, and a circle and the contour annular tooth of roll flute arranged on the maximum gauge of abrasive disc.Pot mill according to claim 1, what it is characterized in that material-feeding plugboard respectively has a rubber blanket up and down, above a rubber blanket be embedded in the rectangular channel of hopper, below a rubber blanket be embedded in the rectangular channel of body.Pot mill according to claim 1 is characterized in that the endoporus of rotor is being adorned the compression spring that is enclosed within on the main shaft, and the thrust bearing between adjusting handle and the rotor is contained in the centre bore of cover, between rotor and the cover sealing ring is arranged.

Make present widely used taper abrasive disc into spherical abrasive disc, and quiet abrasive disc is installed on the abrasive disc seat that can do plane adjustment campaign, can easily the gap of all directions between quiet abrasive disc and the moving abrasive disc be adjusted to equally size.The two sides of abrasive disc all is a spherical, some the teeth of opening along warp direction are arranged on the sphere, the largest circumference of abrasive disc has a circle and the contour annular tooth of roll flute, teeth groove is not on the external cylindrical surface of abrasive disc, so just stoped not levigate material from the big side of refining plate interval and teeth groove drop out may, guarantee that material behind the mill is thin and evenly.Outside the interpolation water outflow machine that prevents material, the rectangular rubber pad of square hole in the middle of respectively filling up lastblock, the upper and lower of material-feeding plugboard is arranged, and rubber blanket embeds in the square table annular groove of body and hopper.Contact with material for fear of the abrasive disc adjusting device, the compression spring is contained in the endoporus of rotor, the rotor that abrasive disc is installed is stretched in the hole of cover, bearing is not contacted with spring with material with sealing ring.

The concrete structure of utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is the profile according to the pot mill that the utility model proposes.

Fig. 2 is the structural map of spherical abrasive disc.

Describe details and working condition in detail below in conjunction with Fig. 1 according to the embodiment that the utility model proposes.

Rotor 7 with main shaft 11 rotations that can be in axial sliding is housed on the main shaft 11 that the motor 20 among this embodiment drives, and the end outer surface that rotor 7 stretches into crushing teeth cover 1 has two spiral helicine muscle.The endoporus of rotor 7 is equipped with a spring 9 that is enclosed within main shaft 11 front ends, fixing moving abrasive disc 6 with sunk screw on the spheric disk of rotor 7, pressing close to move being mounted in of abrasive disc 6 can make quiet abrasive disc 5 on the abrasive disc seat 4 of plane adjustment campaign with respect to body 15, and abrasive disc is adjusted the back and is fixed on the body 15 with bolt 2 and packing ring 3.The two sides of moving abrasive disc 6 and quiet abrasive disc 5 is the sphere of same radius, and sphere has some teeth along warp direction, and the tooth of the contour ring-type of a circle and roll flute is arranged on the greatest circle of sphere, and promptly teeth groove is not on the external cylindrical surface of abrasive disc.The top of body 15 is hoppers 16, is material-feeding plugboard 17 between body 15 and the hopper 16, and the upper and lower of plate 17 respectively has a centre that the embedding hopper 16 of square hole and the

interior rubber blanket

18,19 of rectangular channel of body 15 are arranged.Rotor 7 other ends stretch in the centre bore of cover 14; there is thrust bearing 13 end of rotor 7; pushing away square shaft, to hold 13 front be adjusting handle 10; after adjusting handle 10 regulates; be fixed on the cover 14 with locking nut 12, cover 14 and changeing has sealing ring 8 protection bearings not invaded by the interpolation water of material and material particles between 7.

During pot mill work, pour material into hopper, starting motor is opened material-feeding plugboard 17, material enters crushing teeth cover 1, carry out just brokenly, first material after broken is brought between the sound abrasive disc by the spiral of rotor 7, because the extruding of abrasive disc and rubbing, material is by levigate, flow out between the abrasive disc, be pooled to the grinding machine outlet, flow out outside the machine again.
