Adapter is connected with reductor, reductor and motor connection.
The agitator is semicircle agitator, and its one end is connected by bearing with reactor shell, the other end and air inlet
Mouth connection；The position of the agitator is fixed.When reactor shell is rotated, internal agitator is fixed, and inwall, which is slipped over, to be stirred
Device edge is mixed, by under the powder band on wall.
Manhole is additionally provided with below the reactor shell.
Chuck is additionally provided with outside the reactor shell.Chuck can lead to organic heat carrier or steam, to provide reaction
Required heat.Reactor wall mirror finish.
