The effect of screw-type agitators on powdered materials
Thread Content
The company uses a screw-type mixer in its production process; the upper part of the screw moves upward while the lower part moves downward. There is a star feeder at the discharge outlet, but it was found that this feeder often blocks the discharge outlet, resulting in uneven material flow. The material inside the star feeder also accumulates, and it is in powder form, similar to flour. Has anyone encountered this problem before? How can it be resolved to increase the material discharge rate?……
The upper part of the stirrer is raised while the lower part is pressed down in order to enhance backmixing and facilitate a better reaction. Perhaps the downward pressure on the lower part increased the bulk density of the powder, resulting in difficulties in discharging it. It could be considered that reducing the degree of downward pressure on the lower part during technical upgrades should solve the problem.
What was said downstairs makes sense, but it’s important to get the amount of force used to push downward just right
Pressing down on the discharge opening increases density, and the compacted material tends to form lumps; therefore, mixing must play a role in activating it. It is recommended that the lower part also be designed with an upward slope.
