Plant for centrifugal spraying “Granule-2500”

Appointment


Plant for centrifugal spraying “Granule-2500” is designed to produce metal powders of highly reactive metals and titanium alloys by centrifugal spraying of workpieces, plasma melted by the heater in an inert gas medium with simultaneous transportation of the obtained powder materials in bulk airtight container without air contact.

 

Advantages of the model


Plant is equipped with universal drives block (diameters of loading electrodes - 50-60-70-80 mm...).
Wide range of the electrode feed significantly increases productivity.
Double-rod roller mechanism with buffer spring reduces vibration of the plant.
IIn the vacuum system are using quiet sliding vane rotary pumps and turbo-molecular pump, which reduces the pumping time.
Adjustment of the moving mechanism of the plasmatron is carried out by two coordinates.
