DEVICE FOR PRODUCTION OF TITANIUM PELLETS Russian patent published in 2023 - IPC C22B1/16 F27B21/06 G01N15/08 

FIELD: non-ferrous metallurgy.

SUBSTANCE: device for the production of titanium pellets includes a granulator 1, a screen 2 and a roasting machine containing heating and drying zones, a roasting zone and a cooling zone with the corresponding vacuum chambers 3, 4 and 5, as well as individual vacuum pumps 6, 7 and 8. The device is additionally equipped with a measuring vacuum chamber 9 connected to an individual vacuum pump 10 and installed on the roasting machine in front of the vacuum chamber 3 of the drying zone. Measuring vacuum chamber 9 is equipped with a vacuum stabilization system and an air flow control system. In this case, the vacuum stabilization system includes a vacuum control sensor 11, an actuator 12 and a damper 13 installed on the measuring vacuum chamber 9. The air flow control system includes an air flow control sensor 14 and an extreme regulator 15 connected through an actuator 16 with a damper 17 for regulating the water flow.

EFFECT: invention provides simplification of the control of the firing process, improvement of the quality of the finished product due to the operational control of the elements of the device and optimization of the gas permeability of the charge layer.
