Abstract
The utility model provides a two-storehouse lifting circular trench classification liner plate which comprises an installation screw hole; a circular arc-shaped groove is arranged on the surface of the liner plate; the circular arc-shaped groove is provided with a circular trench for a steel ball to drop in; and the radius of the circular arc-shaped groove is 1.2 times to 1.5 times of that of the steel ball. The two-storehouse lifting circular trench classification liner plate prolongs the service life of the liner plate and saves the equipment repair cost, so that the steel ball grading capability can be improved and the production efficiency is improved.
Description
Technical field
The utility model relates to a kind of two storehouse classifying lining boards, relates in particular to a kind of two storehouses that are used for ball mill and promotes the circular groove classifying lining board.
Background technology
Two storehouse ball mills require liner plate that enough service life and higher classifying capability will be arranged.During ball mill work, steel ball rotates with the ball ball grinding cylinder, and when rotating to certain angle, steel ball separates with ball grinding cylinder, and steel ball is done projectile motion, and last steel ball is pounded to liner plate; Liner plate design commonly used has arc groove, liner plate arc groove radius and the design of steel ball radius ratio are unreasonable, steel ball and liner plate single-point contact phenomena can appear, cause the impulsive force of contact point very big, liner plate very easily weares and teares and will often change, the service life of liner plate is not long, has increased maintenance of equipment expense and operating cost.General liner plate surface outline curves does not have high low head, and the steel ball classifying capability is not high, and ball mill production efficiency is not high.
Summary of the invention
The purpose of this utility model provides a kind of two storehouses and promotes the circular groove classifying lining board, can solve ball grinding machine lining board and need the often technical problem of replacing because of wearing and tearing.
The purpose of this utility model realizes as follows: a kind of two storehouses promote the circular groove classifying lining board, comprise the installation screw, it is characterized in that: the liner plate surface is provided with arc groove, and arc groove forms the circular groove that steel ball is fallen into, and the arc groove radius is 1.2-1.5 a times of steel ball radius.A kind of two storehouses described in the utility model promote the circular groove classifying lining board, it is characterized in that: the contour curve radius on liner plate surface is 2-2.3 a times of steel ball size.
The structure that the utility model adopts, liner plate surface design arc groove formation circular groove increases steel ball and liner plate contact area, reduces the suffered impulsive force in liner plate surface, in the service life of protection liner plate, prolongation liner plate, saves the maintenance of equipment cost; Liner plate surface profile line is designed to high harmonic curve, promotes the steel ball classifying capability, has improved production efficiency.
Description of drawings
Content of the present utility model is easier to be expressly understood in order to make, and according to specific embodiment also in conjunction with the accompanying drawings, the utility model is described in further detail below:
Figure 1 shows that lining plate structure schematic diagram of the present utility model,
Figure 2 shows that liner plate contour curve structural representation of the present utility model,
1, steel ball 2, arc groove 3, contour curve
The specific embodiment:
With reference to accompanying drawing, a kind of two storehouses promote the circular groove classifying lining board, comprise the installation screw, and the liner plate surface is provided with arc groove 2, and arc groove 2 forms the circular groove that steel ball 1 is fallen into, and arc groove 2 radiuses are 1.2-1.5 times of steel ball 1 radius.As another kind of embodiment of the present utility model, contour curve 3 radiuses on liner plate surface are 2-2.3 times of steel ball 1 diameter.
The surface of two storehouses lifting circular groove classifying lining board has been designed some roads arc groove 2 and has been formed circular grooves through calculating meticulously, and the radius of arc groove 2 is 1.2-1.5 a times of steel ball 1 radius; Because the assurance of arc groove 2 sizes, guarantee that the steel ball 1 and the contact point of liner plate become two point from single-point, the increase of contact point, every average stamping press that bears of liner plate has just tailed off, the noise that pit on the liner plate also reduces thereupon, collides is step-down also, prolonged the service life of liner plate like this, reduced the maintenance cost and the operating cost of equipment.The liner plate surface is provided with height contour curve 3, and sweep is 2-2.3 a times of steel ball size, and the classifying capability of steel ball 1 promotes like this, has improved the production efficiency of ball mill.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the above only is a specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of being made, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
Claims (2)
1. a storehouse promotes the circular groove classifying lining board, comprises the installation screw, and it is characterized in that: the liner plate surface is provided with arc groove, and arc groove forms the circular groove that steel ball is fallen into, and the arc groove radius is 1.2-1.5 a times of steel ball radius.
2. a kind of two storehouses according to claim 1 promote the circular groove classifying lining board, it is characterized in that: the contour curve radius on liner plate surface is 2-2.3 a times of steel ball size.
