The invention relates to evmatics-6 for adjusting the amount of fine

and annealing for the separation of a material-inclined perforated bottom 7,

sizes of more than 10 mm for two products. Under the bottom there are nozzles 8 for

that on the boundary grain 50.02 mm, the supply of air, in the lower part of the lattice

Known pneumatic classification-installed discharge device

a torus comprising a hull with a perforated large fraction 9; the classifier has

The varnish fixture is L-il; as follows.

The disadvantage is the low effective Source material by the loading of separation, by the manual 16 is fed to the lower part:

The closest to the technical dry- 15 first separashunnaya column 3, and n. the achieved "result" is pre-inflated with air and swayed properly; the pneumatic class-e "is introduced into the second separation column, a sifter that includes the body, vertical-Under the second column part of the material, the drinking stacks that form the separation column go upwards into its inner the cavity, the noHiibi with the convertible adapters, 20 is divided into a small and crusty perforated inclined bottom, patra-product. A small piece of air by the air inlet for air supply, the charging device is discharged into the discharging device of the fine-tuning device and the loading device fraction 4, the large one is lowered onto the lens of the large and small fraction 127.; the bottom and with the remaining mass of material

The disadvantage is the low quality moves under the third column, where

in class}) jacin, the separation process is repeated. Pass

The chain of inventiveness is an increase in the quality of all steps of the enumeration, the large class 1 coarse: fications, are removed from the bottom to the unloading

The goal is achieved by the adaptation of the coarse fraction 9, and the small pneumatic classifier, the JQj fraction by air flies into the unloading body, the vertical stacks, the cutting device 4, inside of which are separate separation columns with overloaded screw 5, Air with particles, joint devices mi, perforated passage 5 of the tunnel 5, twisted, in the face of the shodntshe, the pipe for supplying permeable particles (maloduha, boot device and unloading gpjjjjjjjjjj j dvigakugs with air flow large and finely dispersed in a cyclone, and, incidentally by: fractional, supplied with fixed, large particles are thrown out in the discharge device by means of centrifugal vultures to the walls of the scraper chain with a screw and slide, set the discharge tool and unload the tool, and unload the tool, and unload the tool, and unload the tool, and unload the tool, and unload the tool, and unload the device and unload the tool, and unload the device, and unload the device and unload the tool, and unload the tool, and unload the tool, and unload the tool, and unload the tool, and unload the device, and unload the tool, and unload the device, and unload the tool, and unload the device, and unload the device, and unload the device, and unload the tool, and unload the device, and unload the device, and unload the device and unload the tool, and unload the tool, and unload the device, and unload the device, and unload the device, and unload the device and unload the tool, and unload the device. separation columns, fine fraction 4, and return to the oblique sides of the unloading unit, the machine, thus, occurs between the passage with the possibility of vertical-add to the clean-up of the small product, scheni, wherein step vintaVrem residence particles in the apparatus is equal to the width of the separation uveshiezsa onnoy kolonshllichivaets that advantageously skazyvaets and unloading schiyuthyubpetie Meleki FrvK | The destruction of conglomerates, Shnberamn Ch1Sh, is complete with cylindrical forips, 6 determines the amount of material,

FIG. 1 shows the class chator) about-ipsyupayuyu to clean up, and thus

Backwards in FIG. 2 is a section (Go1 | fine adjustment of the arcshaft; Pneumatic classifices are contained according to a given separation limit and the housing C t class}) of the catcher; There are three semi-columns, above which the Schleshoi are clean, small fine large products, and the fixture is installed. Past 1 Classification of the thin 1 Food of the Fine fraction 4, which has a colored air separation from the cyclone II, and which form. Inside the remote-accessory device — it comes from the bottom of a small fraction — installed on the sub-device of the large fraction 9, the lower screw 5 (vshggova: surface),

having a screw pitch equal to the width of the shafts. The cylindrical shape of the discharge

Upper honor is provided by fitting the gaps of the interfacial section to the auger with a screw-screw screw surface, which ensures an inertial effect in the automatic splitting stage and improved the fine-tuning of the fine product, by improving the separation pattern and improving the screw surface.

The presence of fine cleaning of the product makes it possible to increase the time spent by the particles in the apparatus, which also has a positive effect on the quality of separation and increases the brittleness of the destruction of xsglomlate ;.

the installation in the upper part of the nepjaropoIIOK gates makes it possible to adjust the amount of small product entering the list into the channel from the previous one; This allows; more precisely tune shsarag to depois along a given ravdvesh border and autonomously regulate the end of the grace of the material in each mine.

The application of the proposed viral chifter allows for better quality split | III by 1.5.2%.% And increasing the productivity is 112-1 fS times.
