Description
Technical field
The utility model relates to engineering mechanical device accessory field, is specially a kind of ball mill wearing chamber wall assembly.
Background technology
In existing ball tube mill, ball milling cylinder is to be all directly sleeved in ball mill rotating shaft by rigid thread structure, and its mechanical milling process is to drive ball milling cylinder to rotate by rotating shaft, thereby drives the ball-milling medium motion of the inside to realize the grinding operation to raw material.In this process, because material and ball-milling medium are relative sliding state and have certain impulsive force in ball milling cylinder, thereby itself and ball milling cylinder have wearing and tearing in normal operation, its more serious position of wearing and tearing comprises ball milling inner wall of rotary drum, the inwall seam crossing of access hole and ball milling cylinder, the inhomogeneities of this wearing and tearing often can cause ball milling cylinder normally to use, and the axial seam place attenuation of ball milling cylinder, lost efficacy, and then cause the wearing plate slippage in the wall of chamber to be lost efficacy, shorten the service life of whole ball milling cylinder, and cross quick-wearing and also can increase the iron-holder in material, affect end product quality.
Utility model content
The technical problem that the utility model solves is to provide a kind of ball mill wearing chamber wall assembly,, to solve the defect in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of ball mill wearing chamber wall assembly, comprise ball milling cylinder and interior wall embeded, this interior wall embeded is embedded in the barrel inner side of ball milling cylinder and goes up and be connected by spot welding mode, described interior wall embeded comprises some lining body units, its each lining body unit is independent moulding, it comprises the base plate of laminating ball milling cylinder, protruding and panel, described panel is that wear-resistant ceramic is made, be molded directly within base plate inner surface, and described protruding be molded on base plate, top extending panel is also provided with " ∠ " type projection in position, panel top layer one side, the extreme higher position side of this " ∠ " type projection is positioned at lining body unit edge, and the acute angle of whole " ∠ " type projection points to consistent with the rotating direction of ball milling cylinder.
In the utility model, the thickness of described wear-resistant ceramic panel is 50 ~ 80mm.
In the utility model, the angle angle of described " ∠ " type projection is 15 ~ 20 °, and its protruding extreme lower position is consistent with the height of the upper surface of panel.
In the utility model, the base plate shape of described liner plate unit and the shape of cylinder inboard wall adapt, preferably curved plate.
In the utility model, for improving the bonding strength of panel and base plate, between panel and base plate, be connected by dormant bolt, in order to ensure that ball milling cylinder chamber wall is an integral planar after installation, without interstitial hole, increased the abrasionproof of chamber wall entirety.
Beneficial effect: the utility model compact conformation, safe and reliable, good integral strength, working surface hardness are high, easy installation and removal, long service life, that potassium steel, rich chromium cast iron are more than 3～4 times, can effectively reduce material and the wearing and tearing of ball-milling medium to inwall seam crossing simultaneously, reduce the iron content in finished product, improve the end product quality of ball milling material, and can extend the service life of ball milling cylinder, thereby improved economic benefit.
Brief description of the drawings
Fig. 1 is the schematic diagram of the utility model preferred embodiment.
Wherein: protruding of 1-ball milling cylinder, 2-base plate, 3-panel, 4-.
Detailed description of the invention
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to the preferred embodiment of a kind of ball mill wearing chamber wall assembly of Fig. 1, in the present embodiment, in the present embodiment, ball mill wearing chamber wall assembly comprises ball milling cylinder 1 and interior wall embeded, and the rotation direction of whole ball milling cylinder 1 is for rotating counterclockwise, and interior wall embeded comprises that being array-like is arranged in the lining body unit on ball milling cylinder 1 inwall, the moulding of each lining body unit independence is connected on the inwall of ball milling cylinder 1 by spot welding mode.
In the present embodiment, each lining body unit includes base plate 2, panel 3 and protruding 4, the arc high manganese steel sheet that its base plate 2 adapts for the shape of base plate shape and ball milling cylinder 1 cylinder inboard wall, the wear-resistant ceramic panel that panel 3 is 80mm for thickness, between panel 3 and base plate 2, be connected by dormant bolt, in order to ensure that ball milling cylinder chamber wall is an integral planar after installation; And protruding 4 be molded over the marginal position of base plate 2, its top is " ∠ " type projection, this " ∠ " type projection towards as shown in the figure, and angle angle is 20 °, extreme higher position side is positioned at lining body unit edge, and extreme lower position is consistent with the height of the upper surface of panel 3.
More than show and described general principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
