Top connect transmission device, bottom connector drum portion, the shell portion be epicoele and cavity of resorption, between by dividing plate split, every
The duct that material passes through is provided with plate, helical axis one end is connected on motor, and the other end is placed in the epicoele of barrel through dividing plate
In cavity of resorption, spiral and lower spiral are respectively equipped with the helical axis in epicoele and cavity of resorption；Barrel cavity of resorption downside be provided with to
Mine mouth, upside is provided with ball feeding mouth, and epicoele top side is provided with gape.
Further, the epicoele of the barrel and lower cavity wall are equipped with abrasion-proof backing block.
Further, different abrasive medias are filled in the epicoele and cavity of resorption of the barrel in grinding, cavity of resorption grinds
Abrasive media of the grinding media specification more than epicoele.
Further, it is equipped with abrasion-proof backing block on the upper and lower helical blade surface.
Further, the duct that the dividing plate is provided with that material passes through is multiple, and the duct is strip hole arranged in parallel,
The strip hole of adjacent two row is staggered, and material enters epicoele by duct from cavity of resorption.
Further, more than the helical pitch of upper spiral, lower helical pitch is 1.1-1.5 times of upper helical pitch to the helical pitch of the lower spiral.
Beneficial effects of the present invention are：
1. the present invention is existed after reductor by the power that the motor in transmission device is exported by axle supporting drive spire
Rotation in barrel.Milling medium has upward movement tendency under spiral drive, is rotated under Action of Gravity Field and frictional force, and
Spire agitation is lower to be produced along cylinder circumference and diametric multi-dimensional movement, so as to produce abrasive action to material.
2. the present invention is provided with abrasion-proof backing block in barrel inwall, is partitioned into epicoele and cavity of resorption, the spiral of spire
Also two sections are partitioned into, the spiral in cavity of resorption is big compared with the lead of screw in epicoele.Using structure of the present invention, grinding efficiency
Height, saves energy consumption.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Fig. 2 is the half sectional view of Fig. 1 median septums.
In figure：1. transmission device is connected, 2. axle support, 3. barrel, 4. epicoele, 5. dividing plate, 6. spire, 7. cavity of resorption,
8. helical axis, 9. plays spiral, 10. goes up spiral, 11. feed ports, 12. ball feeding mouths, 13. gapes, 14. motors, 15. ducts.
Specific embodiment
The present invention will be described in detail with reference to the accompanying drawings and examples.
Embodiment：As shown in figure 1, the tower vertical mill of a kind of two-chamber of the invention, including motor 14, connection transmission device 1, axle
Support 2 and barrel 3, axle support 2 tops connection transmission device 1, and bottom connector drum portion 3,3 points of the barrel is epicoele 4
With cavity of resorption 7, between split by dividing plate 5, the duct that material passes through is provided with dividing plate 5, the one end of helical axis 8 is connected to motor 14
On, the other end is placed in the epicoele 4 and cavity of resorption 7 of barrel 3 through dividing plate 5, is set respectively on the helical axis in epicoele 4 and cavity of resorption 7
There are upper spiral 10 and lower spiral 9；The downside of cavity of resorption 7 of barrel 3 is provided with feed port 11, and upside is provided with ball feeding mouth 12, the top of epicoele 4
Side is provided with gape.The epicoele 4 and the inwall of cavity of resorption 7 of the barrel 3 are equipped with abrasion-proof backing block.The upper spiral 10, lower spiral shell
Abrasion-proof backing block is equipped with the blade surface of rotation 9.Play a part of to protect inwall and blade, and increasing friction force, beneficial to material
Grinding.
In the epicoele 4 and cavity of resorption 7 of the barrel 3 different abrasive medias, the abrasive media of cavity of resorption 7 are filled in grinding
Abrasive media of the specification more than epicoele.As shown in Fig. 2 the dividing plate 5 is provided with the duct 15 that multiple materials pass through, the duct 15
It is strip hole arranged in parallel, the strip hole of adjacent two row is staggered, material can enter epicoele by duct from cavity of resorption 7
