Abstract
The utility model discloses a partition panel for overflowball mill, the partition panel comprises the fan -shaped comb board of a plurality of pieces, opens the rectangular shape comb hole that has along comb board width direction distributes on every block of comb board, and the width in comb hole enlarges to the exit end from the entrance point gradually, the comb hole is equipped with the aequilate section that one section width equals at the entrance point. Set up the aequilate section that the width equals through the comb hole at the comb board at the entrance point for partition panel comb hole width when wearing and tearing remains unchanged, has improved partition panel comb hole sizer branch effect, can improve the grainding capacity of ball mill, can reduce the use amount of front compartment steel ball and back storehouse steel section moreover, reduces the artifical work load that adds the ball.
Description
Technical field
The utility model relates to the ball mill that ore grinding is used, specifically a kind of for overflowball millPartition panel.
Background technology
The partition panel of overflowball mill is generally made up of some fan-shaped grate plates, and large end is fixed with boltOn grinding mill barrel, small end links together by center plectane and other grate plates. In every grate plate, haveThe strip comb hole distributing along grate plate width, the width in comb hole expands to Way out gradually from importGreatly. Be milled to the material that is less than comb hole, under the promotion of new feeding material, entered next through comb holeStorehouse is until overflow. Partition panel attenuation under the long-term impact of steel ball and friction, comb hole width can increase graduallyGreatly. When comb hole width changes the control that can have influence on ball mill fineness index when serious, be to ensure to produceIndex is stable, needs to improve the use amount of front storehouse steel ball and rear storehouse steel section; The timesharing of comb hole sizer due to exist everyStifled aniseed phenomenon between the board plane of storehouse, causes fineness screening inhomogeneous, causes grinding machine fineness and produces negativeLotus declines.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, provides a kind of for overflow type ball millingThe partition panel of machine, can prevent from, because the wear and tear sieving capacity that causes of partition panel declines, improving ball millGrainding capacity.
For achieving the above object, the utility model has adopted following technical scheme: if described partition panel hasThe fan-shaped grate plate composition of dry piece, has the strip comb hole distributing along grate plate width in every grate plate,The width in comb hole expands to port of export direction gradually from entrance point; Comb hole is provided with one section of width at entrance pointEquate wide section.
Further, the length in wide section of comb hole is at 7～8mm.
The beneficial effects of the utility model are: at entrance point, width phase is set by the comb hole in grate plateDeng wide section, make partition panel whens wearing and tearing the hole width of combing remain unchanged, improved partition panel comb holeScreening effect, can stablize for a long time slurry fineness and produce load, can improve the grinding energy of ball millPower, and can reduce the use amount of front storehouse steel ball and rear storehouse steel section, reduce the workload that manually adds ball,Thereby can make system reach steady production index, and improve system driving rate. With 80 tons/hourOverflowball mill is example, and manually adding ball workload can be reduced to three times by a Thursday time, and 1 year reducesMore than 100 tons of steel ball use amounts.

Detailed description of the invention
Below in conjunction with accompanying drawing, the technical scheme in the utility model embodiment is carried out clearly and completelyDescribe.
Fig. 1,2 is depicted as a fan-shaped grate plate 1 of composition partition panel. The large end 11 use bolts of grate plate are solidFix on grinding mill barrel, small end 12Yong center plectane and other grate plates link together. In grate plate 1, openThere is the strip comb hole 2 distributing along grate plate width.
As shown in Figure 3, the width in comb hole 2 expands to the port of export 22 gradually from entrance point 21; Comb hole2 are provided with wide section 23 that one section of width equates at entrance point 21.
The shifting board of this routine overflow type grinding machine is made up of 28 fan-shaped grate plates 1. Grate plate 1 thickness 70mm,The width of comb hole 2 entrance points 21 is 8mm, and the width of the port of export 22 is 18mm.
Wide section of 23 length in comb hole 2 are too small, and the hole 2 width sizes that make to comb easy to wear become large;Wide section of 23 length are excessive, are unfavorable for improving the production load of grinding machine. Therefore, wide section of 23 lengthL is preferably in 7～8mm.
Claims (2)
1. for the partition panel of overflowball mill, described partition panel has some fan-shaped grate plates (1) composition,In every grate plate (1), have the strip comb hole (2) distributing along grate plate width, the width of comb hole (2) certainlyEntrance point (21) expands gradually to the port of export (22); It is characterized in that: comb hole (2) are provided with one at entrance point (21)Wide section (23) that Duan Kuandu equates.
2. the partition panel for overflowball mill according to claim 1, is characterized in that: combThe length L in hole wide section (23) is at 7～8mm.
