Abstract
The utility model discloses a wear-resisting compound welt of bimetal of ball mill, including arc welt and wave welt, the trough tip of wave welt with the arc welt welds together mutually, the arc welt is close to wave welt one side be provided with the fixed lug of wave welt wave form looks adaptation, the arc recess has been seted up on fixed lug top the utility model discloses in, the arc welt closely laminates with the barrel inner wall, and the wave design of wave welt has improved the area of contact of ball and welt, has reduced the consumption of the mill body with the welt, and after the wearing and tearing of wave welt crest consumed, the arc recess contacted with the ball simultaneously, the arc recess formed new wave form contact surface with wave welt trough, has improved the wear resistance of welt greatly, has increased life.
Description
Technical Field
The utility model relates to a welt technical field specifically is a wear-resisting compound welt of bimetal of ball mill.
Background
The main part of the ball mill is a low-speed rotary cylinder body arranged on two large bearings, a lining plate is arranged on the inner wall of the cylinder body, when the ball mill rotates, a grinding body is attached to the lining plate on the inner wall of the cylinder body of the mill under the action of centrifugal force, rotates together with the cylinder body and is taken to a certain height, and under the action of gravity, a free parabola falls down to crush materials in the cylinder body. On the cross section of the mill, about 54 percent of steel balls are lifted and thrown out; 46 percent of the steel balls slide and roll while sliding downwards, so that grinding action is generated among the grinding body, the lining plate and the materials, and the materials are ground. The abrasion of the lining plate mainly comprises abrasive abrasion, corrosion abrasion and impact fracture, the contact area of the traditional lining plate structure is smaller, the action efficiency of the ball mill is low, and the grinding quality is influenced.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a wear-resisting compound welt of bimetal of ball mill to solve the problem that proposes in the above-mentioned background art.
In order to solve the technical problem, the utility model provides a following technical scheme:
the utility model provides a wear-resisting compound welt of bimetal of ball mill, includes arc welt and wave welt, the trough tip of wave welt with the arc welt welds mutually together, the arc welt is close to wave welt one side be provided with the fixed lug of wave welt wave form looks adaptation, the arc recess has been seted up on fixed lug top.
As an optimized scheme of the utility model, arc recess radian is less than wave welt wave form radian.
As a preferred scheme of the utility model, arc welt is made by the chromium carbide alloy material.
As a preferred scheme of the utility model, the wave welt is made by tungsten carbide alloy material.
To sum up, the utility model discloses following beneficial effect has: the arc liner plate is tightly attached to the inner wall of the barrel, the contact area between the grinding balls and the liner plate is increased due to the wavy design of the wavy liner plate, consumption of the grinding body and the liner plate is reduced, and meanwhile, after wave crests of the wavy liner plate are worn and consumed and the arc grooves are contacted with the grinding balls, the arc grooves and wave troughs of the wavy liner plate form new wavy contact surfaces, so that the wear resistance of the liner plate is greatly improved, and the service life of the liner plate is prolonged.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Examples
Referring to fig. 1, the utility model provides a wear-resisting compound welt of bimetal of ball mill, including arc welt 1 and wave welt 2, the trough tip of wave welt 2 welds with arc welt 1 mutually together, and arc welt 1 is close to wave welt 2 one side and is provided with the fixed lug 3 with wave welt 2 wave form looks adaptation, and arc recess 4 has been seted up on fixed lug 3 tops.
Preferably, the arc of the arc-shaped groove 4 is less than the wave-shaped arc of the waved lining plate 2.
Preferably, the arc-shaped liner plate 1 is made of a chromium carbide alloy material.
Preferably, the waved backing plate 2 is made of a tungsten carbide alloy material.
The embodiment of the utility model provides an in, arc welt 1 closely laminates with the barrel inner wall, and the wave design of wave welt 2 has improved the area of contact of ball and welt, has reduced the consumption of mill body and welt, and after 2 peak wear of wave welt consumed simultaneously, arc recess 4 and ball contact back, arc recess 4 forms new wave form contact surface with 2 troughs of wave welt, has improved the wear resistance of welt greatly, has increased life.
It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
