Abstract
A matching structure of a ball mill end liner and a feeding bush, comprising an end liner (3), a feeding bush (2), and an end cap (1). The end liner (3) is installed on the left of the end cap (1), and the feeding bush (2) is installed under the end cap (1). The utility model is characterized in that the end liner (3) is installed above the feeding bush (2).
Description
Technical field:
The utility model relates to the fit structure of end lining of a ball mill plate and charging lining.
Background technology:
φ 5.03 * 6.4m overflowball mill that operation is at present used be China in the eighties in last century, have a world-class at that time grinding attachment from what Canadian AC company introduced, the liner plate replacement cycle of this grinding machine was generally about 8 months.Wherein aside-liner is divided into two kinds of outer ring aside-liner and inner ring aside-liners.Even the new aside-liner of installing cooperates situation good with end cap, yet has arrived the middle and later periods of wear liner, find to have produced very big space between inner ring aside-liner and the end cap, and the inside, space has filled up the broken steel ball that differs in size.Since the abrasion of broken steel ball and ore pulp circulation is arranged, the wear of end cover aggravation, and this will cause quite serious consequence.The main cause that produces this phenomenon is: existing inner ring aside-liner and lining fit structure are unreasonable, mill diameter is big, liner plate is heavy, liner plate can produce very big centrifugal inertial force in the operation process, must cause bolt looseness like this, so produce the gap between aside-liner and the end cap.In a single day and having produced the gap, some less broken steel balls will be squeezed in; Along with the diameter of clamp-oning broken steel ball increases gradually, the gap between aside-liner and the end cap also constantly increases.Meanwhile, broken steel ball and ore pulp circulation are also aggravating the end cap of will having to change at last to the abrasion of end cap.
Summary of the invention:
The purpose of this utility model just provides the fit structure of a kind of end lining of a ball mill plate and charging lining, and this fit structure can prevent that broken steel ball from entering, and prolongs the service life of end cap.
In order to realize this purpose, the utility model adopts following technical scheme:
Comprise aside-liner, charging lining and end cap, described aside-liner is installed in the left side of end cap, and the charging lining is installed in the bottom of end cap, and the aside-liner bottom then is installed in the top of charging lining, and described aside-liner is made by rubber.
The utlity model has simple in structure, characteristics such as result of use is good.
Description of drawings: Fig. 1, existing aside-liner and charging lining fit structure schematic diagram
The state diagram that Fig. 2, broken steel ball enter end cap
Fig. 3, structural representation of the present utility model
1, end cap 2, charging lining 3, aside-liner
The specific embodiment:
Contrast Fig. 1 as can be known: the aside-liner 3 on the existing ball mill is installed in a side of charging lining 2; charging lining 2 does not form good protective action to aside-liner 3, causes between aside-liner and the end cap in case produced the situation that the gap will cause broken steel ball as described in Figure 2 to enter end cap.
Contrast Fig. 3 as can be known: the utility model aside-liner 3 is installed in the left side of end cap 1, charging lining 2 is installed in the bottom of end cap 1, aside-liner 3 bottoms are installed in the top of charging lining 2, form matched in clearance, this fit structure, even produce the gap between aside-liner and the end cap, broken steel ball does not advance end cap yet, and described aside-liner 3 is made by elastomeric material.
Claims (2)
1, the fit structure of a kind of end lining of a ball mill plate and charging lining, comprise aside-liner (3) and charging lining (2) and end cap (1), aside-liner (3) is installed in the left side of end cap (1), charging lining (2) is installed in the bottom of end cap (1), it is characterized in that aside-liner (3) bottom is installed in the top of charging lining (2).
2, fit structure according to claim 1 is characterized in that described aside-liner (3) made by elastomeric material.
