Double axis mixer is suitable for continuous mixing of mixed fertilizer powder, generally after the automatic batching equipment of the fertilizer production process. The working principle is that the material enters the mixing tank, is uniformly stirred through a pair of spiral blades installed on a pair of oppositely rotating double shafts, and enters the next granulation process of the organic fertilizer and NPK fertilizer production line.
The double shaft mixer is mainly composed of the casing,the screw shaft assembly,the driving device,the piping,the cover plate,the chain cover and the like.The specific structural performance characteristics are as follows:
1.The shell is mainly composed of sheet metal and section steel.It is welded and formed in the factory and assembled with other components.It is the support of the double shaft mixer.The shell is tightly sealed and there will be no fly ash and ash leakage.
2.The screw shaft assembly is the main component of the double shaft mixer.Its components mainlt include left and rright sprial shafts,bearinng seats,bearing sleeves,bearin sleeves,bearing covvers,gears,sprockets,oil cups,blades and other components.
When the dry powder material enters the body evenly through the feed intake through the feed intake, the power drive machinery drives the spiral spindle with multiple groups of blades to rotate, and the passive spiral shaft is driven by the meshing transmission gear to rotate the main shaft at the same speed, so that the material is stirred and pushed to the humidifier section of the tank body. After the material is pushed to the humidifying section, the humidifier automatically sprays the material and then fully stirs up the mixing section after the tank. When the material reaches the controlled humidity, it is discharged from the discharge port and enters the next process.
