Abstract
The invention discloses a kind of efficient hard alloy agitating ball mill, include mixing drum and rotating shaft and mixing arm on support body, the rotating shaft is connected with actuating unit and engine, the grommet of multiple unitary circulars is installed on the mixing drum inwall, the grommet and the rotating shaft and the mixing arm are made by Hardmetal materials, the multiple vertical arc grooves in grommet inner side.The present invention causes because of hardness, intensity, wearability deficiency easy to wear compared with prior art, when can solve existing hard alloy agitating ball mill grinding hard alloy powder, and service life is short, influences the problem of powder quality.Grinding efficiency, reducing energy consumption can also be significantly improved.
Description
Technical field
Cemented carbide powder powder material is ground the present invention relates to machining technology field, especially a kind of agitating mode
Efficient ball mill.
Background technology
At present, the domestic existing means of abrasion for grinding the ball mill of cemented carbide powder powder material still uses stainless steel
Material makes, and because its hardness is low, wears no resistance, thus when cemented carbide powder powder material is ground, not only the interior bucket of ball mill
Wall part is easily worn and torn, and influences the service life of ball mill；Meanwhile, what ball mill fell when inner barrel wall weares and teares in process of lapping
Carefully cut powder to be doped into hard alloy powder, reduce the purity of hard alloy powder, significantly impact the items of powder
Energy.
In addition, the structure of existing hard alloy stirring ball mill is existed typically using the agitating mode for rotating vertically
Hold in the mixing drum of hard alloy powder, the rotating shaft of rotation is erect and along rotating shaft to surrounding hair using stainless steel mixing drum middle part
Multiple mixing arms of distribution are dissipated, in grinding, this structure can cause hard alloy powder directly serious with stainless steel mixing drum
Friction, due to the hardness of stainless steel mixing drum, intensity, wearability is not enough and it is easy to wear to cause, and the effect of grinding is poor, uses
Life-span is shorter.
And, the grinding drum inner barrel wall of existing stirring ball mill is cylindrical surface structure, when grinding is rotated, due to
Mixing drum inwall is smooth, cylindrical peripheral surface, and ball milling powder is focused mostly in mixing arm mixing drum due to the effect of centrifugal force, ball milling powder
Inwall is rolled and rushes down motion, it is difficult to form convection current collision, and this structure can cause alloyed powder abrasive lapping efficiency low, and the effect ground
It is really poor, generally by grinding to reach a good grinding effect for a long time, making for ball mill is reduced indirectly
Use the life-span.
The content of the invention
The present invention provides a kind of efficient hard alloy agitating ball mill, can solve existing hard alloy agitating ball mill
Grinding hard alloy powder when because hardness, intensity, wearability deficiency cause it is easy to wear, service life it is short and influence powder quality
Problem, grinding efficiency, reducing energy consumption can also be significantly improved.
In order to solve the above problems, the technical scheme is that：Include the mixing drum on support body and rotating shaft
And mixing arm, the rotating shaft is connected with actuating unit and engine, and multiple overall circles are provided with the mixing drum inwall
There is more than 1 mill ball in the grommet of shape, mixing drum, the grommet, rotating shaft, mixing arm and the mill ball are closed by hard
Golden material is made, it is characterised in that：The grommet inner side has on the inside of grommet multiple vertical arc grooves, vertical arc groove
Radian of the radian more than the mill ball.
In above-mentioned technical proposal, more specifically scheme can be：The installation of every grommet and the inner wall of rotary drum
Bonded by adhesive seal at thin seam.
Know-why of the invention, rotating shaft drives mixing arm circular-rotation, drives ball milling material along an inwall movement is mixed, and passes through
The vertical arc groove in grommet inner side is crossed, changes motion track, ball milling material is got rid of into the middle part to mixing drum, with other ball milling things
Material forms effective collision, improves the grinding efficiency of ball milling material.In addition, mill ball and ball milling powder under mixing arm shock to stirring
A liner collision is mixed, ball milling material forms impact, can improve mill ball with mill ball to the arc-shaped groove bottom of mixing drum liner
With effective contact area of ball milling powder, grinding efficiency is improved.
By adopting the above-described technical solution, the present invention has the advantages that compared with prior art：
1st, the inner barrel wall position of this hard alloy agitating ball mill uses and is made with hard alloy powder identical material, both
Severity of grind is improve, the service life of equipment is improved, operating efficiency is improve, the equipment powder for being worn is turn avoid
It is different from powder and influence the performance quality of powder；
2nd, the special construction design inside the mixing drum of this hard alloy agitating ball mill, by original stainless steel inner barrel wall
Change the inner barrel wall for inlaying integrally-built grommet into, such as under identical load, use the ball mill two or three of prior art
Year is changed once, and uses this technology estimated replacement cycle more than 15 years.
3rd, grommet is designed to unitary circular by this hard alloy agitating ball mill, and it is recessed to set vertical arc on the inside of benefit ring
Groove, significantly improves grinding efficiency, relative to ordinary rigid alloy agitating ball mill, in the identical powder of grinding, and reaches expection
The time of effect shortens more than one times.
