During material so that the inner barrel wall part of ball mill is easily worn and torn, the service life of ball mill is influenceed；Meanwhile, when inner barrel wall weares and teares
The powder of stainless steel for falling, is doped into hard alloy powder, reduces the purity of hard alloy powder, significantly impacts powder
Processing performance.
The content of the invention
Problem to be solved by this invention is to provide a kind of efficient, reliability, can be good at ensureing hard alloy powder again
The grinding method of processing performance.
In order to solve the above problems, the technical scheme is that：The efficient ball grinding method of this hard alloy powder is：Will
After cemented carbide powder powder stock is sufficiently mixed, feeding hard alloy rotary mill is ground；The hard alloy roller ball
Grinding machine includes the roller on support body, and the roller connects configuration in engine, the roller by actuating unit
There are the balls of multiple, be embedded with the grommet of multiple unitary circulars on the inner wall of rotary drum, in every grommet and the mixing drum
The installation of wall is carefully bonded at seam by adhesive seal；There is an arc groove grommet inner side, and the radian of arc groove is big
In the radian of mill ball；The grommet and the ball are Hardmetal materials and are made.
Preferably, the installation of the grommet and the inner wall of rotary drum is carefully bonded at seam by adhesive seal.
Preferably, the hard alloy rotary mill, also including lid, lid is used to seal balling drum, covers
Air inlet and bleeding point are provided with body, after cemented carbide powder is put into balling drum, ball mill are rolled by bleeding point
Cylinder is vacuumized, then the one kind in argon gas or nitrogen is input in balling drum by air inlet, by controlling ball milling
Atmosphere in machine cylinder, it is to avoid alloy powder is aoxidized, influences powder product quality.
Preferably, the hard alloy rotary mill, also including cooling water recirculation system, cooling water recirculation system bag
Include water pump, water leg, nozzle.Water pump and water leg, nozzle are connected by conduit, and arrangement of nozzles is led in cylinder outer wall surrounding
Cross water pump to extract the water of water leg out, sprayed in cylinder outer wall by nozzle, for cooling down balling drum.
Operation principle of the invention：The present invention by by the grommet and mill ball of hard alloy rotary mill use with it is hard
The material of the close trade mark of matter alloy powder is made so that does not have impurity during ball milling and is doped into hard alloy powder, reduces
The purity of hard alloy powder, and influence the properties of powder.In addition, grommet is designed into unitary circular, and mending in ring
Side sets arc groove so that when rotary mill works, alloy powder is concentrated in bottom portion of groove, and grinds spheroid also in arc
Circumference rolling is carried out in connected in star, effective milling area of mill ball and alloy powder is improve.
By adopting the above-described technical solution, the present invention has the advantages that compared with prior art：
1st, effective grinding part of the grinding method of this hard alloy powder is used and hard alloy powder identical material
It is made, has both improved the service life of equipment, improves operating efficiency, the thin powder and mixed cut that turn avoid that inner barrel wall weares and teares
Close powder different and influence the properties of mixed powder；
2nd, the special construction design of the drums inside in the ball mill that the grinding method of this hard alloy powder is used, by original
The mosaic mode arranged by polylith liner plate having has been changed into be inlayed by the grommet of unitary circular structure, and bonding strength increases, also not
Can be because one block of liner plate comes off so that entire row liner plate all comes off, the functional reliability of whole ball mill is greatly improved, interior
The replacement cycle of grommet greatly prolongs；
3rd, grommet is designed to unitary circular by the ball mill that the grinding method of this hard alloy powder is used, and is being mended in ring
Side sets arc groove so that when rotary mill works, alloy powder is concentrated in bottom portion of groove, and grinds spheroid also in arc
Circumference rolling is carried out in connected in star, effective milling area of mill ball and alloy powder is improve.

Specific embodiment
Implement to be described in further detail embodiment one below in conjunction with the accompanying drawings：
The grinding method of this hard alloy powder includes operating according to the following steps：After hard alloy powder is sufficiently mixed,
Feeding hard alloy rotary mill is ground；
Hard alloy rotary mill shown in Fig. 1, Fig. 2 includes the roller 4 on support body 1, one end of roller 4
Bottom is provided with, one end is provided with lid, covers and offer a feeding and discharging mouthful；Roller 4 is rack-mounted on four rolling, and roller 4 passes through power
Transmission device 3 connects engine 2, and actuating unit 3 herein is gear drive, and engine 2 herein is speed governing electricity
Machine.
As shown in Fig. 3, Fig. 4, Fig. 5, the grommet 5 of multiple unitary circulars is installed on the inwall of the roller 4 of ball mill, each
