The embodiment of the application solves the problem of low discharge rate of the mill by providing the liner plate of the mill cylinder body with high discharge rate.
In order to solve the technical problems, the general idea of the embodiment of the application is as follows:
in the embodiment of the utility model provides an in, the backing plate includes: a lifting section; the promotion section sets up to the echelonment, and the cooperation promotes the strip and carries out two rounds to ore and steel ball in the mill barrel and promote, and it is higher to promote the height, and the height that falls of ore and steel ball is high to increase the effective work area who grinds the ore, effectively promoted the crushing efficiency of ore, makeed the ejection of compact rate of mill higher.
In order to better understand the technical solution, the technical solution will be described in detail with reference to the drawings and the specific embodiments.
Example (b):
as shown in fig. 1, the utility model provides a mill barrel welt of high discharge rate, the barrel welt includes: a backing plate 10 and a lifting strip 20; the lifting strip 20 presses and fixes the backing plate 10 on the inner wall of the mill cylinder, and the lifting strip 20 is connected with the mill cylinder through bolts; the pad plate 10 includes: a lifting section 11; the lifting section 11 is arranged to be in a step shape, and is matched with the lifting strip 20 to lift two wheels of ore and steel balls in the cylinder body of the mill, so that the lifting height is higher, the falling height of the ore and the steel balls is high, the effective working area of the mill (namely the area of the cylinder liner plate contacted with the ore and the steel balls) is increased, the crushing efficiency of the ore is effectively improved, and the discharging rate of the mill is higher.
