Embodiment Construction

[0008] The present invention will be further described below in conjunction with the accompanying drawings.

[0009] As shown in Fig. 1 and Fig. 2, the present invention comprises plate body 1; The surface of described plate body 1 is provided with convex hemispheroid 2 and concave hemispheroid 3 by rows and columns; radius r 1 , the radius of concave hemispheroid 3 is r 2 .

[0010] The plate body 1 is provided with convex hemispheroids 2 at odd rows, odd columns and even rows and even columns, and concave hemispheroids 3 at odd rows, even columns, and even rows and columns of the plate body 1 .

[0011] The radius r of the convex hemispheroid 2 1 and the radius r of the concave hemispheroid 3 2 Both are greater than or equal to the radius of the grinding media.

[0012] The radius r of the convex hemispheroid 2 1 Greater than, equal to or less than the radius r of the concave hemispherical body 3 2 , namely r 1 > r 2 , r 1 = r 2 or r 1 2 .

Abstract

The present invention relates to ball mill, and is especially lining plate of mill. The lining plate includes plates with convex semi-spheres and concave semi-spheres on the surface. The present invention has reasonable and simple design, and can raise the capacity of ball mill and lower the power consumption of ball mill.

Description

technical field [0001] The invention relates to a grinding device, in particular to a mill liner for a ball mill, an autogenous mill or a rod mill. Background technique [0002] Most of the currently used mill liners have a flat, convex-convex or stepped surface. The use of the above-mentioned liners makes the mill low in productivity and high in energy consumption. Utility model content [0003] The object of the present invention is to provide a mill liner for ball mills, autogenous mills or rod mills with reasonable design, simple structure, high mill productivity and low energy consumption. [0004] In order to achieve the above object, the technical solution adopted by the present invention is: a mill liner, including a plate body 1, characterized in that: the surface of the plate body 1 is provided with a convex hemispherical body 2 and a concave hemispherical body 3 . [0005] Compared with the prior art, the present invention has the following advantages: the pre...
