Abstract

The invention relates to the grinding of ores, materials by vibratory mills in the chemical, construction and other fields. The purpose of the invention is to increase the efficiency of process control. Each rus of obliquely mounted and rigidly connected grinding pipes rests elastically on a fixed frame and is equipped with an autonomous vibration exciter. Pipes are equipped with intermediate and end perforated partitions. At the nodes of elastic communication between the Rus, the geometric centers of the adjacent end partitions of the adjacent ends of the Rus are arranged vertically. The upper and lower additional Rus may have different vibration parameters. The tiers can be technologically articulated in parallel, serial or mixed circuits. 7 il.

Description

The invention relates to the grinding of ores, rocks, materials, namely, vibratory mills, and can be used in the mining, chemical, construction and other industries, in the processing and production of fertilizers and secondary resources.

The purpose of the invention is to increase the efficiency of process control.

FIG. shows the structural diagram of the proposed mill, front view; in fig. 2 - the same, side view; in fig. 3 - grinding pipe, longitudinal section; in fig. 4 — node I in FIG. one; Fig. 5 is a sequential pattern of pairing Rus; in fig. 6 - paraple-pipe scheme; in fig. 7 - mixed scheme.

The working body of the mill is a rus of predominantly identical cross-section tubes 2 rigidly connected by traverses 3, connected in block-modules 1, rigidly connected by cross-beams 3, and integrally with its elastic supports 4 on the supporting frame 5 (Fig. I). Between the pipe and 2, the pathogen 6 (Fig. 2) is circularly mounted, oscillating with a drive in the form of a transmission-7 and an engine 8. Box 9 combines the functions of the reception of preparatory grinding, mixing and distribution of raw materials.

In each pipe 2, chambers 10 (fig. 3) of shapes are formed by sleeves 11, lining J2, perforated partitions 13 and meyushml 14 behind, of this size, loading # 1m- {via lyut 1b. Pipes can have external

cover The geometric centers of the adjacent end partitions (Fig. 4) of the mating Kotzov Rus are located on the same vertical, so that the joint node 16 can be formed of structurally simple elements in the form of nozzles 17 with flanges 18 and an elastic or flexible sleeve 19.

The box 9 can also be elastically articulated with the loading chute 20. Technological studs 21 are convenient for mounting and dismounting the elements of chambers 10, The preferred angle of inclination of the drums to the horizon is about 30 °. In the mill in FIG. 1 and 2, an additional lower rus of the same grinding pipe with autonomous resilient supports and an autonomous pathogen, the characteristics of which may be different from that of the upper rus, is mounted under the upper blond. In general, the Rus may be somewhat about

In the course of work, each Russian oscillates in a circular trajectory, regardless of the other Rus. In particular, it is advisable that the oscillation frequency of the upper russa was lower, and the amplitude is greater than the lower one.

As material moves from chamber to chamber, the degree of change is increasing. In the zone of the joint node 16 (Fig. 4), pouring promotes the mixing of particles: coarse and fine fractions change places;

Co-structural-technological flexibility, modularity and autonomy of the Rus increase the efficiency of control of the grinding process.
