Description

hr

The invention relates to devices for the wet grinding of materials and may find application in the chemical, construction and other industries.

The known design of a mill for ultrafine grinding of bulk materials, comprising a body divided into cylindrical chambers by vertical partitions coaxial with central holes, a horizontal shaft with disks arranged in cylindrical chambers, plate-shaped swirlers mounted on radially concentric rows on opposite surfaces on one side. partitions and discs mounted on the ends of the disks of a rectangular shaft and reflective strips sorted on the housing.

The disadvantage of this device is the low efficiency of its operation due to the low speed of the crushed material in the axial direction.

The closest in technical essence to the proposed device is a mill, comprising a housing divided into working chambers by vertical partitions with coaxial central holes, and a horizontal shaft with disks mounted in the chambers.

A disadvantage of this device is that the movement of material in the axial direction is random. This leads to a decrease in the performance of the mill, increases the energy consumption caused by overgrinding of the material, reduces the efficiency of the mill.

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

The goal is achieved by the fact that in a disk mill containing a body divided into working chambers by vertical partitions with coaxial central holes, and a horizontal shaft with disks mounted in chambers, the vertical partitions are made in the form of disks with a central hole, which have an outer cylindrical surface - connected to the body by means of springs, and the surfaces of the central holes are made with wavy depressions, while the horizontal shaft is made with a hemispherical and recesses in the number of partitions, in each of which a ball is mounted with the possibility of its movement along a wavy depression, while the horizontal shaft is made hollow with a screw protrusion on the inner surface and with radial

openings extending between the baffles and the shaft disks.

FIG. 1 shows the device, general view, section; in fig. 2 - section AA on

FIG. one; in fig. 3 is a section BB in FIG. one; in fig. 4 shows a section B-B in FIG. one; in fig. 5 is a view of FIG. four.

The disk mill contains a horizontal hollow housing 1.

0 a shaft 2 with a screw protrusion 3 on the inner surface, as well as radial holes 4 and hemispherical depressions 5, in each of which a ball 6 is mounted. The body 1 is divided into cylindrical

5 chambers with vertical partitions 7 made in the form of discs with central apertures 8, while the vertical partitions are connected to the housing with their outer cylindrical surface

0 by means of springs 9. On the surfaces forming the central apertures 8 in partitions 7 there are wavy depressions 10.

On the shaft 2 rigidly fixed disks 11.

5The radial ribs 12 are installed along the disk 11, the latter in the course of the movement of the material. The device has an outlet 13.

The disk mill operates as follows.

The material prepared as a suspension, through a rotating hollow shaft 2 under the influence of a screw protrusion 3, through the radial holes 4 enters the working

5 the space between the vertical partitions 7 and the disks 1.

Vertical partitions 7, interacting through balls 6 with a rotating shaft 2 through wavy

0 holes 10, begin to perform swinging movements. This leads to more intense grinding of the material, as well as accelerated its progress in the axial direction.

5 The crushed material is captured by the fins 12 and is removed through the outlet 13 from the mill.

This disk mill will improve the efficiency of the grinding process.

Claims (2)

Claim 1. A disc mill comprising a body divided into working chambers by vertical partitions with coaxial 5 central holes and a horizontal shaft with discs mounted in chambers, characterized in that, in order to increase the efficiency of the grinding process, the vertical partitions are made in the form of discs with a central a hole, which with its outer cylindrical surface is connected to the housing by means of springs, and the surfaces of the central holes are made with wavy-shaped depressions, while the horizontal shaft is made with hemispherical depressions according to the number of partitions, in each of which are installed Flax ball with the possibility of its movement along a wavy depression. 2. A mill according to Claim 1, characterized in that the horizontal shaft is hollow with a screw lug on the inner surface and with radial holes extending into the space between the baffles and the shaft disks.  3 in Phie 4 - / 0 View C
