rial with 1P; 1Lew and crumbs. At the end of the selection, the arbes serve the hawk into the chamber of B. Pneumatic cylinder 12 to close the upper flap 11.

EU cyclcl is the volumetric determination of a non-left component in a granular material. From the software unit 16 through the rod 10 to the piston-sprayer 4, air, which worms constantly drog;: epr 5 blows the sample of granulated material from pypi and chips through calibrated holes, for example, shaft E, measuring vessel 1. At the same time, air is blown into the chamber In the pneumatic probe 6 and as the fine component is blown from the target component, the piston-sprayer 4 moves along the length of the measuring vessel 1 up to which the spring 8 of the pneumatic probe is designed. In this case, the piston 7 compresses the spring 8, and the valve 9 opens the flow of air from chamber B to chamber D, which is in common with the atmosphere, through program unit 16. Movement of the pistons 7 and the piston of the atomizer 4 is stopped. The linear displacement of the rod 10 is converted into a proportional signal by a pneumatic converter 14, the output being coherently connected with the recording device 15.

After the time specified by software block 16, the second cycle is over and the third one begins — the ejection of the target sample. From the programs a lot of unit 16 injects air into chamber D of the pneumatic probe 6 to retract the piston-dissolver 4 to the initial position and at the same time move the air into the piston-dissolve 4. Then, from the programmer 16, air 8 chamber D of the pneumatic cylinder 13 is opened to open the lower valve 2 measuring vessel 1 for discarding the target sample. After the target sample is ejected, air from the programmable unit 16 is fed into the chamber E of the pneumatic cylinder 13 to close the HHxaiefi valve 2, the device is ready to take the next sample of granular material, which is carried out automatically after the intervals set on the protramty unit 16.

The linear movement of the powder. Spray 4 is directly proportional to the volume of empty in measuring vessel 1 and characterizes the volume occupied by the direct target component of the granular material, which is recorded by the device 15.
