Product description
Product parameters

  Main features:

  1) The item is suitable for powder materials.

  2)310S high temp.-resistant S.S. tube put in the middle of furnace, one end sealed by magnetic fluid, the other end uses clamp-joint rotating seal elements, in order to move materials in and out easier, also monitor the pressure inside tube.

  3) When tube rotating, powder materials can be evenly stirred, not piled up, moreover, when powder discharging, completely auto-discharging in one way, no remains at all.

  4)Widely used to calcine and dry for battery material, non-strong alkali powder material ,granular material

  5)can supply vacuum or gas protection experiment environment.
