Specific implementation mode
The present invention will be further described in conjunction with the embodiment in attached drawing below：
As shown in Figure 1, the invention mainly comprises ball milling staving 1, the both ends of ball milling staving 1 are separately connected a hollow rotating shaft
2, bearing block 3 is connected on the hollow rotating shaft 2 at 1 both ends of ball milling staving, bearing block 3 is fixed in ball milling rack 4.
Ball milling staving 1 drives the hollow rotating shaft 2 at end to be equipped with transmission gear 5, transmission gear 5 and 6 output end of speed reducer
Drive the engagement connection of gear 7.5 outer ring of the transmission gear is equipped with protective cover 8, and transmission gear 5 is protected by protective cover 8.
It is respectively equipped with helical blade 9 in the hollow rotating shaft 2 at 1 both ends of ball milling staving, when ball milling staving 1 rotates clockwise,
Helical blade 9 can stop that the abrasive material in ball milling staving 1 enters in hollow rotating shaft 2；When ball milling staving 1 rotates counterclockwise, mill
Abrasive material in staving 1 can enter in helical blade 9 in the case where the gas with pressure is blown.
2 outer end of hollow rotating shaft at 1 both ends of ball milling staving connects air valve 11 by rotatory sealing 10 respectively, passes through 11 energy of air valve
Enough control the closing and unlatching of 2 internal channel of hollow rotating shaft.
As shown in Fig. 2, 1 both ends of ball milling staving are equipped with guide cone circle 13, multiple spiral disturb is equipped in guide cone circle 13
Flowing plate 14, multiple spoilers 14 are circumferentially uniformly distributed.Material can enter guiding by pellet separating plate when because of ball milling
In cone circle and hollow rotating shaft, Gu Daoxiangzhuiquan is mounted with spoiler, and material is prevented to enter in hollow rotating shaft.
As shown in figure 3, being equipped with pellet separating plate 12 on the inside of 1 both ends of ball milling staving, pellet separating plate 12 is equipped with multiple equal
The separating tank of even distribution.The inner wall of ball milling staving 1 is equipped with ball milling liner 15, and ball milling liner 15 is equipped with multiple baffles 16, more
A baffle 16 is uniformly distributed along 1 circumferencial direction of ball milling staving.Multiple baffles 16 are arranged in ball milling staving 1 to mention sphere more
Eminence falls, and increases the dynamics that sphere hits material, to improve the efficiency of ball milling.
The ball milling staving 1 is equipped with feed inlet 17 and service hatch 18, and feed inlet 17 and service hatch 18 are setting up and down.
The present invention operation principle be：When ball milling works, ball milling bucket, ball is added by the charge door of ball milling staving in material
Grinding barrel body both ends air valve is closed, and ball milling staving makees 360 ° of continuous rotation movements and carries out ball milling operation in an axial direction.Due to ball milling staving

Rate.Material can be entered in guide cone circle and hollow shaft by pellet separating plate when because of ball milling, and Gu Daoxiangzhuiquan is mounted with spoiler,
There are also installed helical blades for hollow rotating shaft, and when ball milling bucket rotates in the forward direction, spoiler and helical blade will produce one to ball milling bucket
Interior thrust, thrust returns to material in ball milling bucket across pellet separating plate, so not will produce ball milling dead angle；When discharging
Air valve is opened, and ball milling staving is with direction of rotation when ball milling on the contrary, the suction generated by high pressure positive blower, makes entire unit generate negative
Pressure condition.Air outside ball milling bucket body is entered by ball milling staving one end hollow rotating shaft in ball milling bucket body due to pressure difference, from another
End takes the powder of milled in ball milling bucket body into deduster out of, powder since gravity is moved to deduster bin bottom,
It being discharged by Star-like unloader, filtering of the gas through filter bag is discharged by wind turbine mouth, since wind turbine is continuous work, while ball milling
Bucket is ceaselessly to rotate in an axial direction, finally all goes out the powder in ball milling bucket to the greatest extent；In addition, baffle carries material when due to discharging
It falls to eminence, generates airborne dust and be easy to be taken out of by air-flow, accelerate discharging speed, and go out very clean；Guide cone circle simultaneously
The spoiler of installation so that air enters ball milling staving and generates revolving dispersion, and material in ball milling bucket is driven to rapidly flow toward ball
The grinding barrel other end after material enters the guide cone circle of the other end, accelerates flow direction of material hollow shaft by the effect that above carries of spoiler,
To improve discharging efficiency.
The present invention improves the working efficiency of discharging and ball milling, and easy to operate, rationally distributed, reduction labor intensity passes through
Powder is sucked out in blower negative pressure, and discharging speed is fast and clean, avoids powder and goes out not cause totally the intersection of different batches of product dirty
Dye；Spoiler and helical blade prevent material from entering in hollow rotating shaft；Mill inner wall of barrel is mounted with baffle, can mention sphere more
Eminence falls, and increases the dynamics that sphere hits material, to improve the efficiency of ball milling；Pellet separating plate is directly installed on ball milling bucket
Interior, ball milling need not exchange for when discharging, easy to operate, reduction labor intensity.
