AI Technical Summary

Problems solved by technology

In practice, however, achieving the desired grading effect in this manner is difficult and often by chance
These plates are also relatively very heavy and as the corrugations wear down, the grading effect is reduced
These ripples must not be too pronounced, or a discontinuous lift occurs, that is, when the outer layer of the milled packing is lifted into the top area of ​​the mill and falls back into the liner instead of falling and along the milling liner. This discontinuous lift is severe when the base of the packing rolls

Embodiment Construction

[0024] [24] According to the present invention, a certain number of liners are shaped in the form of a deflector 20 as shown in FIGS. 1 and 2, wherein FIG. 1 is a top view of the deflector 20, and FIG. Outline drawing seen in the direction of , which also indicates the direction of rotation of the mill. Each deflector comprises a base plate 22 with a central hole 24, which is to be fixed to the inner wall of the shell-like barrel section of the mill.

[0025] [25] In the embodiment shown in Figures 1 and 2, on the plate 22, there is a wing 26 formed (cast) as an integral part therewith, standing at one end of the plate 22, preferably perpendicular to the twenty two. The thickness of this wing 26 is between 25 and 50 mm and the height (with respect to the radial height of the mill) is preferably between 100 and 350 mm.

[0026] [26] According to an important feature of the invention, each wing 26 is inclined at an angle α, α Less than 25°, preferably between 5° and 25°.

Abstract

The invention concerns a liner consisting of juxtaposed individual rings of lining plates forming the cover of the cylindrical housing of a rotary mill. The liner consists of a number of lining plates located at selected sites and configured in the form of deflectors ( 20, 30 ) comprising a fin ( 26, 36 ) arranged on edge on a base plate ( 22, 32 ) fixed to the housing and forming an angle less than 25° relative to a diametral plane of the mill.

Description

technical field [0001] [1] The present invention relates to a liner for a rotary tubular mill comprising a cylindrical shell-shaped barrel section for accommodating material to be ground and a grinding body packing, Wherein the liner is composed of a ring formed by juxtaposed independent liners. Background technique [0002] [2] The object of the present invention is particularly to provide a mill for grinding cement (sintered body) in a dry process and coal, limestone and ore in a wet or dry process. These mills consist of a metal cylindrical shell-like section that rotates about its longitudinal axis and contains a grinding filler consisting of grinding bodies, usually spherical or cylindrical stones of different sizes, Spherical stones etc. The materials to be milled are introduced from one side of the mill, and as they run towards the outlet on the opposite side, they collide and mill between the milling bodies. [0003] [3] Conventional mills are generally divided in...
