Abstract

The invention relates to linings of drum mills for the wet grinding of various materials, and can be used in the mining, chemical, building materials industry and other industries. The purpose of the invention is to improve the reliability of the mills due to the unification of lining plates. To do this, on the bottom and side surfaces of the plates 1 in the plane perpendicular to the axis of the mill drum, there are recesses 5.6 in the corner configuration, and in the middle part of the bottom surface of the plate - recess 7 of the T-shaped configuration. During the installation of the lining, sections of the corners are inserted into these recesses, which allows the shelves of these corners to divide the channels between the plates into sections whose length does not exceed half the width of the plate, and also to use for the lining of the drum mills slabs of the same size. 6 Il.

Description

FIG. 2

The invention relates to linings of drum mills for the wet grinding of various materials, and can be used in the mining, chemical, industrial materials and other industries.

The purpose of the invention is to improve the reliability of the mills due to the unification of lining plates.

02, the corners 9 are installed in the T-shaped recess 7 of the plate 02 on the side of the plate 03 (Fig. 4) and the corners 9 on the side of the opposite end cover of the drum, after which the plate 0z is installed and all the plates of this row are bolted (not indicated) . Then the corners 9 are installed in the depressions 5 on the side of the next row of plates: C |, Cr, C3 (Fig. 4) and their installation is made

FIG. 1 shows the liner Yu in the same way as the plates of row Yes 0. The installer is a top view; in fig. 2 is a section through the subsequent rows of plates produced AA in FIG. one; in fig. 3 - view

in fig. one; in fig. 4 - part of the drum shell, top view, on which the burners of a large unit capacity. In addition, the corners 9 overlap and a continuous channel of width H (Fig. 4), formed by 6oj forged walls of plates and lined with one

the same way. Thus, the length of the channels formed by the side walls of the plates does not exceed half the width

lining plates lined with lining, which is especially important for the corners between them; in fig. 5 - wide plates that use the drum shell with the lining mounted on it, cross section; in fig. 6 - the nature of filling the channels between the lining plates of the material to be crushed and scrap when the angles are set - 20 end covers of the drum, like. Dimensions of metal angles sizing Lining the grinder mill will vary depending on the geometric

the dimensions of the lining plates used can be in the range from 50X50 mm to 100X100 mm.

25 For the first time after re-furnishing, the channels formed by plates and lining of the end covers of the drum, the width of which can reach iO-20 mm, will not be a continuous zinc-shaped cavity in the form of a rectangular plate 1 with holes 2 for fastening the lining to the mill drum with bolts. On the side surfaces 3 and 4, the recesses 5 and 6 are made, which have the angle configuration, and the recess 7, which has a T-shaped configuration, is made in the middle part of the lower surface 8.

The dimensions of the depressions 5-7 are performed by a pulping flow, which abrades

the inner surface of the shell of the drum. The latter is due to the fact that along their entire length, these channels are divided into sections by corners of the corners 9, the length of which does not exceed half the width of the legs, so that when lining plates are mounted when metal corners 9 are installed between them, the gap between all recess walls and the surface

metal corner allowed free- ...., "-"

Placement of the corner in the recess. Thermo plate. In the process of further In practice, it is advisable to install the operation of a canal mill in its futher gap of at least 5–8 mm. The height HI of the hammer is clogged with scrap and particles (Fig. 1) and the width H2 (Figs. 1 and 2) of the material to be ground (Fig. 6).

the grooves must match the width. Thus, the proposed lining

corner shelf 8 and plus 5-8 mm. The length of the grind mills not only prevents the dimples Nz (Fig. 3) is taken as 40 rotates the wear of the drum shell, but also 1.5-2 heights of the angle, and the length of the angle 9 allows to make all lining

plates of one standard size instead of three or four, and in some cases of a larger number of standard sizes of lining plates.

Claims (1)

Invention Formula there should be no more than two lengths of holes Nz. Such a length is determined by the fact that even with a minimum gap between the side walls, it is possible to establish corners. The installation of the lining plates is as follows. First, the installation of the first row of linings in the drum, for example the row in FIG. 4, indicated. 0. For this The lining of an ore grinding mill containing plates fixed on the inner surface of the drum of the mill is of FIG. h, and aachennigi. and. Jiuiu is made of bolt fasteners, on the side of the end cover of the drum, which is characterized by the fact that the corners 9 are laid in order to increase, after which the reliability of the mills is maintained due to the unification of the lining plates on the bottom and side surfaces of the plates in the plane perpendicular to axis of the mill drum. plate 0i (Fig. 4) is set so that the corners 9 enter the T-shaped recess 7, and the holes 2 for the bolts coincide with holes in the shell of the drum. Then 55 are made indentations on the configuration the corners 9 are installed in the T-shaped corner, and in the middle part of the lower surface, the 7-plate 0i is deepened on the plate-side of the plate - a T-shaped depression You are 02 (Fig. 4), the plate is set. 02, the corners 9 are installed in the T-shaped recess 7 of the plate 02 on the side of the plate 03 (Fig. 4) and the corners 9 on the side of the opposite end cover of the drum, after which the plate 0z is installed and all the plates of this row are bolted (not indicated) . Then the corners 9 are installed in the depressions 5 on the side of the next row of plates: C |, Cr, C3 (Fig. 4) and their installation is made as well as slabs of row 0. Installation of the subsequent rows of slabs is carried out flax large unit of power. In addition, the corners 9 overlap and a continuous channel of width H (Fig. 4), formed by 6oj forged walls of plates and lined with one  lining plates, which is especially important for wide plates that are used on the drum middle covers, the dimensions of the metal corners of the knocking out flow of pulp g u l g g g o LJ ti 1 g iTi gtg P (P v.
