Abstract

The invention relates to powder metallurgy, in particular, to installations for mechanical alloying. The purpose of the invention is to increase the service life. Through the neck 13, the material to be processed is loaded into the chamber 1 and the drive is turned on. The platform begins to rotate and the grinding bodies 2 are pressed to the bottom by the action of centrifugal force. The working bodies 4, rotating together with the rotor 3 inside chambers 1, mix the grinding bodies 2, which process the material between them, which then flows through the discharge channels in the bottom part of the chamber into the receiving area of the elevator 6. The elevator rotates from the gear 7. This material returns to the chamber through the receiving bin 9, ensuring a constant circulation of the material being processed. After the required processing time has passed, the rotary valve 10 is transferred to the unloading position in the storage bin 11. The circulation of the material eliminates the formation of "dead zones" and, consequently, rotor wear. 1 il.

Target1 invention - increased service life,

The drawing shows the proposed device

Device containing; 1 horizontal CASE and 1st rotary driven platform (not shown). On the platform, a radar is mounted around its axis. Its directional axes of the camera 1 are directed by their axes. Each chamber 1 is filled with grinding bodies 2 and located in it) Um with rotor 3 connected to the drive and equipped with a working machine —ra 4 and bottom 5; Around each camera 1 is mounted a RING fan 6, connected to the drive through testein 7, hard :; mounted on the rotor 3.

In the bottom part of the chamber, chambers 1 are made on less than one loading channel with a cross-sectional size of no more than half of the small meter 2 meter. bottom 5.

which intensively process the material between them, which then flows through the discharge channels in the bottom of the chambers 1 to the receiving zones of the elevators 6, which, rotating from gear 7, continuously return this material to the chambers 1 through the receiving bunker 9, ensuring constant the circulation of the material being processed in these chambers. After the required processing time has expired, the rotary valve 10 is converted into 1T by means of the rod 12 (application for unloading and the processed material coming from the elevators 6 is discharged into storage bins 11, which are periodically removed to unload the material.

The advantage of the proposed device is that it is the first to solve the problem of ensuring the complete circulation of the material being processed in the field of action of centrifugal forces that exist. It reduces the wear rate of the mixing rotor, where the scraper blade of the rotor is subject to the most wear due to its friction against the material pressed in the dead zone. This wear can only be avoided if the dead zones are eliminated,
