The specific embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, below in conjunction with specific embodiment, and with reference to accompanying drawing, the present invention is described in more detail.
With reference to figure 1 and Fig. 2, be respectively the B place partial enlarged drawing of the structural representation of embodiment of the present invention grinding roller and millstone sheet and Fig. 1.
During work, described grinding roller 5 is placed on millstone sheet 6, and the wear surface 1 of described grinding roller 5 and the wear surface 7 of millstone sheet 6 are in contact with one another, and described grinding roller grinds along millstone sheet.
Described grinding roller 5 and millstone sheet 6 comprise matrix 3 and the castingin many ceramic rods 2 in matrix 3, described ceramic rod 2 respectively along wear surface 7 castingins of the wear surface 1 of grinding roller and millstone sheet in matrix 3, the length direction of described ceramic rod 2 keeps substantially vertical with described wear surface 1 with wear surface 7 respectively.An end face of described ceramic rod 2 is embedded in described matrix 3 inside, and the other end of described ceramic rod 2 overlaps with wear surface 7 surfaces of the wear surface 1 of described grinding roller and millstone sheet respectively.
With reference to figure 3 and Fig. 4, it is the cutaway view of the structural representation of embodiment of the present invention grinding roller and the A-A in Fig. 3.As one embodiment of the present of invention, ceramic rod 2 length of castingin in grinding roller are 0.3～0.6 times of grinding roller wall thickness.The complete castingin of described ceramic rod 2 can reduce the vibration of grinding roller in running in matrix 3.
Need to prove, described wear surface (1 and 7) is exactly outer surface or the processing work face of grinding roller and millstone sheet, and described grinding roller wall thickness is grinding roller wear surface 1 to the distance of grinding roller inwall 4.
As an alternative embodiment of the invention, the length of the ceramic rod 2 of castingin in millstone sheet can be also 0.3～0.6 times of millstone sheet wall thickness.Described millstone sheet wall thickness is millstone sheet wear surface 7 to the distance of millstone sheet inwall 8.
Preferably, the length of described ceramic rod 2 and grinding roller and the millstone sheet degree of wear are preferably corresponding, i.e. the large position of the degree of wear, and ceramic rod is longer, the position that the degree of wear is little, ceramic rod is shorter.
Alternatively, described matrix 3 is selected from any one in medium managese steel, low-alloy steel, ni-hard cast iron and rich chromium cast iron.Utilize its performance to improve the service life of grinding roller.
