(54) BEETED MILL SEPARATOR (57) The invention relates to the technique of fine and ultrafine grinding and is intended to separate the suspension of the crushed material from the grinding bodies in bead mills. The purpose of the invention is to increase reliability and provide the ability to adjust the separation gap. The bead mill separator contains a body 1, equipped with a mounting flange 2 and a drain pipe 3, and a separating screening cartridge, made in the form of a cylindrical spring 4 and provided with a sucker mechanism, which allows changing the spring pitch of the coils. 1 il.

The invention relates to the technique of fine and ultrafine grinding, intended to separate the suspension of crushed material from the grinding bodies and can be used as a special unit of bead mills in the production of dyes, building materials, in the enrichment of ores and in other sectors of the industrial industry.

Mainly, two types of separators are used to separate the suspension of ground material from the grinding media in bead mills: dynamic or disk separators. Known sieve separators, in particular, the cartridge type. The advantages of these separators are that they can be quickly replaced with an in-stitch, without disassembling the mill and in their compactness.

A known mill with a mixing mechanism, equipped with one or more cartridge-type screening devices, comprising a housing equipped with means for fastening it to the grinding chamber, with a drainage nozzle and a separating screening cartridge fixed in the housing.

The disadvantage of the mill is the rapid wear of the screening cartridge, made of fine wire mesh, with bead particles.

A bead crusher separator is known, comprising a housing provided with a flange for fastening it to the grinding chamber and a drainage nozzle, and a separating screening cartridge fixed in the housing.

The disadvantages of the separator are low reliability due to the rapid deterioration of the filter cartridge made of wire sieve material, resulting in abrasion with its grinding bodies, and clogging of the screening surface with sediment of the material being crushed. These phenomena lead to frequent stops of the mill to replace or clean the separating device.

In addition, when replacing the bead loading in the mill with beads with a smaller particle size, it is necessary to replace the separator with another one with the corresponding cell size of the sieve sieve cartridge.

The purpose of the invention is to increase reliability, ensuring regulation of the separation gap.

This is achieved by the fact that the sifting cartridge fixed in the housing with the drainage pipe is made in the form of a cylindrical spring and a plug fixed to

the end of the spring opposite to the body, and in the case coaxially with the spring is mounted with the possibility of axial movement and fixation of the rod.

The drawing shows the proposed

separator, longitudinal section.

The bead mill separator consists of a body 1, made together with a flange 2 for attachment to the camera body

0 grinding and drain pipe 3, and the separating screening cartridge, made in the form of a cylindrical spring 4 with tightly fitting coils, provided with a stopper 5. The spring 4 is screwed with its extreme coils into a special helical groove of the separator housing. A rod 6 is screwed into the housing coaxially with the spring 4, abutting with its end into the plug of the separation cartridge.

0 Works separator as follows.

The screening cartridge is introduced into the discharge area of the ground material suspension of the grinding chamber and the separator at

5 using the flange 2 is attached to the chamber. The rotation of the rod 6 moves the plug 5 to the right by an amount that provides the necessary clearance between the turns of the spring, as a rule, it is 1/2 the size of a part of the grinding body.

The suspension of the crushed material passes between the coils of the spring 4 from the outside to the inside and through the annular space between the spring and the rod b passes

5 into the housing 1 and through the nozzle 3 is led out of the mill.

The advantages of the proposed separator are as follows: the spring is made of wire significantly

0 larger diameter, which provides increased durability and, consequently, the reliability of the separator; when the mill is in operation, the filter cartridge is in a highly turbulent suspension medium,

5 is subjected to numerous chaotic impacts of the grinding bodies, which ensures the vibration of the stretched spring and its self-cleaning of the surface of the gaps between the turns from the material being crushed, and also contributes to its passage between the turns; The separator has the ability to adjust the size of the screening gap and can be adjusted to work with virtually any size of grinding media.
