The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings and embodiments:

the application discloses novel wear-resisting wet-type lattice ball mill, including end lining board, feeding bush and end cover, as shown in fig. 1, for the structure chart of present end lining board, for solving the problem in the background art, the technical scheme that this application embodiment provided is as shown in fig. 2 to fig. 10.

The first embodiment:

as shown in fig. 2 and 3, the end liner 10 is provided with wear-resistant members, the wear-resistant members are disposed in the range from 1/2 to 3/4 of the lower portion of the end liner 10, and the wear-resistant members are the first reinforcing ribs 20 and the second reinforcing ribs 30 which are symmetrically disposed. As shown in fig. 2, the first reinforcing rib 20 and the second reinforcing rib 30 are parallel to the inclined edge of the end lining plate 10 and extend from the middle to the bottom in the length direction, the first reinforcing rib 20 and the second reinforcing rib 30 are in a step shape, and transition arcs are arranged at the positions connected by the step shape, so that the outer edge of the step shape is in a streamline shape, in the rotation process of the cylinder, a steel ball or fluid in the cylinder can fall along the outer edge of the arc shape, direct impact on the end lining plate 10 is reduced, the smooth edge can facilitate the flow of materials, and the abrasion of the materials on the end lining plate 10 is reduced. The surfaces of the first reinforcing rib 20 and the second reinforcing rib 30 are arc-shaped, the highest point of the first reinforcing rib and the second reinforcing rib protrudes out of the surface of the end lining plate 10 by 2cm, the heights of the two ends of the first reinforcing rib and the second reinforcing rib are gradually reduced, and the first reinforcing rib and the second reinforcing rib extend in the length direction to be fused with the surface of the end lining plate 10.

The applicant finds through experiments that the optimal length of the first reinforcing rib 20 and the second reinforcing rib 30 is 30cm, and the width of the first reinforcing rib and the second reinforcing rib 30 is 4cm, so that the overall added weight is minimized, and the best wear-resisting effect is achieved. The person skilled in the art can also adjust the corresponding dimensions of the reinforcing ribs according to the actual size of the actual ball mill, and the related technical solutions can all be derived from the present application.

Second embodiment

As shown in fig. 4 to 6, the wear-resistant member in the first embodiment may also be a wear-resistant boss 40, the surface of the wear-resistant boss 40 is arc-shaped, a plurality of guide grooves 41 are arranged on the wear-resistant boss 40 in parallel along the width direction, and the plurality of guide grooves 41 extend along the length direction of the wear-resistant boss 40. The width of the guide groove 41 is larger than the diameter of a steel ball used by the ball mill, the spacing distance between every two adjacent guide grooves 41 is smaller than the diameter of the steel ball used by the ball mill, and the edge and the bottom surface of each groove are in a connected arc shape. The guide grooves 41 can reduce the weight of the wear-resistant boss 40, and can guide the steel balls and materials which are in contact with the end lining plate 10, and as the distance between the guide grooves 41 is smaller than the diameter of the steel balls, most of the steel balls which are in contact with the end lining plate 10 move along the guide grooves 41, even if the steel balls are worn, the part between the grooves can play the effect of reinforcing ribs, and therefore the service life of the end lining plate 10 is prolonged.

The highest point of the wear-resistant boss 40 protrudes out of the surface of the end lining plate 10 by 2cm, the length of the wear-resistant boss 40 is 30cm, and the width of the wear-resistant boss is matched with the width of the position where the wear-resistant boss is installed on the end lining plate 10.
