Abstract
The invention discloses a rolling ball mill for hard alloy. The rolling ball mill comprises a drum mounted on a frame. The drum is connected with a power unit through a power transmission device, a plurality of balls are disposed in the drum, a plurality of lining rings formed integrally are mounted on the inner wall of the drum, and the lining rings and the balls are all made of hard alloy materials. Compared with the prior art, the rolling ball mill for hard alloy can overcome problems that when used for grinding hard alloy powder, existing rolling ball mills for hard alloy, which are low in hardness and poor in wear resistance, are easy to wear, low in operation reliability and short in service lives, while quantity of powder is affected.
Description
Technical field
The present invention relates to the Machining Technology field, especially a kind of ball mill that grinds the cemented carbide powder powder material with roll mode.
Background technology
At present, the means of abrasion of domestic existing ball mill for grinding the cemented carbide powder powder material still uses stainless steel material to make, because its hardness is low, wear no resistance, thereby when grinding the cemented carbide powder powder material, not only the inner barrel wall of ball mill part is is very easily worn and torn, and affects the service life of ball mill; Simultaneously, the powder of carefully cutting that ball mill falls when inner barrel wall weares and teares in process of lapping is doped in the carbide alloy powder, has reduced the purity of carbide alloy powder, has greatly affected the properties of powder.
In addition, the general cylinder that adopts non-setting to rotate of the structure of existing carbide alloy rotary mill has carbide alloy liner plate annular to be spliced on this inner wall of rotary drum, certain gap is arranged between the liner plate, when grinding, tiny powder very easily falls into gap location, the reliability of impact processing; This connected mode of backing plate, liner plate is easily loosening and drop in the course of work, and then whole row's liner plate can't be supported and drop when having a liner plate to come off; If there is a liner plate to be worn and need to reinstall or change, strike easily loose whole row's liner plate during replacing, therefore difficult replacing, functional reliability is lower.
Summary of the invention
The invention provides a kind of carbide alloy rotary mill, hardness was low, easy to wear when it can solve existing rotary mill grinding carbide alloy powder, and functional reliability is poor, the problem that service life is short.
In order to address the above problem, technical scheme of the present invention is: this carbide alloy rotary mill includes the cylinder that is installed on the support body, described cylinder connects engine by actuating unit, the a plurality of balls of configuration in the described cylinder, grommet by a plurality of unitary circular on the described cylinder inner barrel wall forms, and described grommet and described ball are made by Hardmetal materials.
In the technique scheme, more specifically scheme can be: the installation finedraw place of every described each carbide alloy grommet and described inner wall of rotary drum is bonding by adhesive seal.
Further: described Hardmetal materials is made by the percentage by weight of following component: the cobalt powder 6%～8% of 1～1.5 μ m, surplus are the tungsten carbide of 1～2 μ m.
Further: described Hardmetal materials is made by the percentage by weight of following component: the cobalt powder 7.8% of 1～1.5 μ m, surplus are the tungsten carbide of 1～2 μ m.
Further: described Hardmetal materials is made by the percentage by weight of following component: the cobalt powder 9%～12% of 1～1.5 μ m, surplus are the tungsten carbide of 2～4 μ m.
Further: described Hardmetal materials is made by the percentage by weight of following component: the cobalt powder 11% of 1～1.5 μ m, surplus are the tungsten carbide of 2～4 μ m.
Further: described Hardmetal materials is made by the percentage by weight of following component: the cobalt powder 12.5%～15% of 1～1.5 μ m, surplus are the tungsten carbide of 2～4 μ m.
Further: described Hardmetal materials is made by the percentage by weight of following component: the cobalt powder 15% of 1～1.5 μ m, surplus are the tungsten carbide of 2～4 μ m.
Further: described Hardmetal materials is made by the percentage by weight of following component: the nickel powder 12%～15% of 2.5～3 μ m, surplus are the tungsten carbide of 3～5 μ m.
Further: described Hardmetal materials is made by the percentage by weight of following component: the nickel powder 13% of 2.5～3 μ m, surplus are the tungsten carbide of 3～5 μ m.
Owing to adopted technique scheme, the present invention compared with prior art has following beneficial effect:
1, effective grinding part of this carbide alloy rotary mill (grommet and ball) adopts with the material of the close trade mark of carbide alloy powder and makes, both improved severity of grind, the service life of raising equipment, improved operating efficiency, the bucket wall powder that having avoided again is worn gets off is different from powder and affect the performance quality of powder;
2, the special construction design of the cylinder inside of this carbide alloy rotary mill, with original grommet that has been changed into unitary circular by the annular array alloy lining, bonding strength increases, can be because an abrading block comes off yet so that whole grommet all come off, the functional reliability of whole ball mill is greatly improved, the replacement cycle of grommet prolongs greatly, for example under identical load, use the ball grinding machine lining board of prior art to take replacing in eight to ten months, install once, and use the grommet three and half of the unitary circular of this carbide alloy rotary mill, grommet did not come off and changed, and the grommet wear extent is minimum, calculate by above-mentioned analysis, estimate that the replacement cycle was above 10 years;
3, this carbide alloy rotary mill uses the structure of grommet, effectively reducing powder falls between the existing ball mill barreling bar splicing liner plate and the drawback in the slit between pad plate and the barrel, the functional reliability of whole ball mill improves greatly, and it is also very convenient to change maintenance.
