Abstract
The utility model is a pot mill scaleboard, the inner wall of the scaleboard's radial section takes on an outer convex surface of a wave shape, the radius of the wave gradually reduces from the center to both sides. The scaleboard whose inner wall takes on a wave shape structure has an obviously enhanced rigidity, is uneasy to deform or crack, and relative sliding is uneasy to happen between the scalboard's inner wall and a steel ball, material, thus the pot mill's work efficiency is improved, the scaleboard's inner wall wearing is reduced, the scaleboard's service life is lengthened. Due to a longer radius of the middle wave, the scaleboard's lifting effect increases, the pot mill's production efficiency is improved, the energy consumption is saved, and the material's crushing and grinding quality is improved.
Description
Technical field
The utility model relates to a kind of cartridge type, awl ball tube mill liner plate.
Background technology
The at present domestic liner plate that is used for cartridge type or awl ball tube mill, the structure of its liner plate cross section is to press entad calibration face design along circumferential two ends of ball mill, inner radial wall is an arc surface.Mainly there is following problem in this structure: 1, the poor structure rigidity of liner plate, yielding under the effect of external force in the use, cracking; 2, relative slips easily takes place between liner plate inwall and steel ball and the material, not only reduced the production efficiency of ball mill, and caused the liner plate inner wall abrasion to be aggravated, lack the service life of liner plate.
Summary of the invention
To be solved in the utility model is that above-mentioned liner plate poor rigidity, liner plate inwall are because of serious wear short problem in service life.
The utility model is to solve like this: the curved surface of the inwall undulate evagination of the radial section of liner plate.The liner plate rigidity of this inwall undulate structure obviously strengthens, not yielding and cracking under the effect of external force, and be difficult for taking place relative slip between liner plate inwall and steel ball, the material, both improved the operating efficiency of ball mill, the liner plate inner wall abrasion is reduced, can improve the service life of liner plate.
In order to improve liner plate service life better, the radius of described wave successively decreases to both sides from the centre, makes the liner plate interior thickness thicken, and can obviously improve its service life.Because middle wave radius is higher than both sides in the course of work of ball mill, liner plate is to abrading-ball and the material effect of haveing a certain upgrade, therefore improved the production efficiency of ball mill, reduced the power consumption of ball mill, and because the raising of castering action, cause the inertia of abrading-ball and material movement to strengthen, the broken mill quality of material is improved.
Description of drawings
Fig. 1 is the utility model liner plate radial section structural representation.
Fig. 2 is for being equipped with the utility model liner plate ball mill working state schematic representation.
The specific embodiment
By shown in Figure 1, the utility model ball grinding machine lining board, its circumferential two ends are for entad dividing angle faces, the curved surface of the inwall undulate evagination of the radial section of liner plate, the radius of each wave successively decreases to both sides from the centre, and the radius R 1 of middle wave is 1.0-1.3 a times of abrading-ball average diameter in the ball mill, R2=0.7, R1R3=0.7R2, by that analogy, the radius R n+1 of each wave of both sides is followed successively by 0.7 times of its adjacent inboard wave radius R n.By shown in Figure 2, the wave of liner plate intermediate projections such as radius are that the projection of R1 and R2 has tangible castering action to abrading-ball 1 and material 2.
Claims (3)
1, a kind of ball grinding machine lining board, its circumferential two ends be for entad dividing angle faces, it is characterized in that the curved surface of inwall undulate evagination of the radial section of liner plate.
2, liner plate according to claim 1 is characterized in that the radius of described wave successively decreases to both sides from the centre.
3, liner plate according to claim 2, the radius R 1 that it is characterized in that described middle wave is 1.0-1.3 a times of abrading-ball average diameter in the ball mill, the radius R n+1 of each wave of both sides is followed successively by 0.7 times of its adjacent inboard wave radius R n.
