Abstract
The utility model discloses a lining plate for a ball mill. The lining plate is connected with a cylinder body of the ball mill, comprises at least two fixing holes and is fixed on the cylinder body through at least two bolts. A single-hole lining plate is replaced by a double-hole lining plate, and the lining plate is fastened by double elliptical bolts and is prevented from being loosened, so that the connection rigidity of the lining plate is improved, and sudden dropping of the lining plate due to cut-off of the bolts is avoided; the contact area between the lining plate and the cylinder body is increased, so that the situations of abrasion and pressing mark extension of the cylinder body are suppressed and eliminated, the service lives of the lining plate and the bolts are prolonged, and an unplanned stopping event is avoided.
Description
Technical field
The utility model relates to a kind of ball grinding machine lining board.
Background technology
Ball grinding machine lining board is for protecting cylindrical shell; make cylindrical shell avoid abrasive body and directly impact and friction of material; also can utilize multi-form liner plate to adjust the motion state of abrasive body simultaneously; to strengthen the pulverization of abrasive body to material; contribute to improve the mill efficiency of grinding machine; increase output, reduce metal consumption.
Ball grinding machine lining board has the various ways such as corrugated liner and ladder lining board.Wherein, corrugated liner has the fin of mildization, and as shown in Figure 3, in a node, rising part is effectively to promoting abrasive body to cutaway view, and some disadvantageous effect of sloping portion.The ladder lining board surface is an inclination angle, makes it synthetic with original angle of friction, becomes many ladders after installation, as shown in Figure 1, can strengthen the thrust of liner plate to abrasive body.
Existing ball grinding machine lining board is the single hole liner plate, as shown in Figure 2 and Figure 4, only establish a fixing hole (fixing hole 11 in Fig. 2, the fixing hole 42 in Fig. 4) on a liner plate, use a set bolt (the oval bolt 12 in Fig. 2 and the oval bolt 41 in Fig. 4) to be fixed.In the single hole liner plate, the ball storehouse is 10 rows, and 24 of every rows deduct 10 of manholes, count 230; Forging storehouse is 17 rows, and 24 of every rows, deduct 10 of manholes, counts 398.In use, the contact area of single hole liner plate and cylindrical shell is little, causes the wearing and tearing of cylindrical shell and impression large, and every block of liner plate only has an oval bolt to fix, liner plate is loosening displacement easily, causes the oval bolt be fixed on cylindrical shell to be cut off, and liner plate comes off, for fear of damaging cylindrical shell, must stop in time and install or change liner plate, greatly limit and produced load, approximately stagnant driving rate, increased maintenance and production cost, urgently improved.
The utility model content
The problem existed for prior art, the purpose of this utility model is to propose a kind of ball grinding machine lining board, by enforcement of the present utility model, improves connection rigidity and the service life of liner plate.
For reaching this purpose, the utility model by the following technical solutions:
A kind of ball grinding machine lining board, be connected with ball mill barrel, and described ball grinding machine lining board has at least two fixing holes, and described liner plate is bolted on cylindrical shell by least two.
Preferably, there are two fixing holes.
Preferably, described ball grinding machine lining board is corrugated liner or ladder lining board.
Preferably, described bolt is oval bolt.
Based on disclosing of above technical scheme, the utility model possesses following beneficial effect:
The utility model, adopt the diplopore liner plate to replace the single hole liner plate, with bielliptic(al) bolted liner plate, prevent that liner plate is loosening, increased the connection rigidity of liner plate, avoided bolt to cut off the generation again that liner plate comes off suddenly, and because the contact area of liner plate and cylindrical shell increases, state of development to cylindrical shell wearing and tearing and impression is controlled and is eliminated, and has improved the service life of liner plate and bolt, has also avoided the generation of unplanned property Parking.
The accompanying drawing explanation
The ladder lining board cutaway view that Fig. 1 is prior art;
The ladder lining board front view that Fig. 2 is prior art;
The corrugated liner cutaway view that Fig. 3 is prior art;
The corrugated liner front view that Fig. 4 is prior art;
The stepped liner plate for ball mill front view that Fig. 5 is the utility model embodiment 1;
The ball mill corrugated liner front view that Fig. 6 is the utility model embodiment 2.
Wherein: 11,42,52,54,62 and 64, fixing hole;
12,41,51,53,61 and 63, set bolt.
The specific embodiment
Further illustrate the technical solution of the utility model below in conjunction with accompanying drawing and by the specific embodiment:
Embodiment 1 provides a kind of ball grinding machine lining board, with ball mill barrel, is connected, and described ball grinding machine lining board has at least two fixing holes, and described liner plate is bolted on cylindrical shell by least two.For ladder lining board, as shown in Figure 5, should there are two fixing holes 52 and 54, can use set bolt 51 and 53 that liner plate is fixed on cylindrical shell.For corrugated liner, as shown in Figure 6, should there are two fixing holes 62 and 64, can use set bolt 61 and 63 that liner plate is fixed on cylindrical shell.
Although in figure, the signal set bolt is oval bolt, reality also can be used the other forms of bolts such as hex bolts.
In the utility model, adopt the diplopore liner plate to replace the single hole liner plate, with bielliptic(al) bolted liner plate, prevent that liner plate is loosening, increased the connection rigidity of liner plate, avoided bolt to cut off the generation again that liner plate comes off suddenly, and because the contact area of liner plate and cylindrical shell increases, state of development to cylindrical shell wearing and tearing and impression is controlled and is eliminated, and has improved the service life of liner plate and bolt, has also avoided the generation of unplanned property Parking.
The above; it is only the preferably specific embodiment of the utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to replacement or changed according to the technical solution of the utility model and utility model design thereof, within all should being encompassed in protection domain of the present utility model.
