The dry powder mixer uses a pair of intermeshing and rotating blades to produce a strong shearing action that allows the semi-dry or rubbery viscous plastic material to react quickly to obtain a homogeneous mixing device. The speed of the two blades is different, depending on the process can set a different speed, the most common speed is 42/28 per minute. So the dry powder mixer for the pressure requirements is very high. When the pressure is insufficient, the following questions arise:

1, the motor coupling wear, need to check or replace the coupling.

2, hydraulic pump or motor steering is wrong, need to check processing.

3, shock devices have problems, need to be checked to tighten or replace the new shock absorption.

4, the motor or hydraulic pump shaft on the drive is cut, you need to check processing.

Hope that the above problems, we can pay attention to it, once the dry powder mixer pressure, will affect the dry powder mixer running, will lose a certain interest, how can not taste ah!

The smaller the mixing gap value, the more the mixing paddle wall and the mixing pot pot wall, the more obvious the dragging effect on the material, the stronger the mixing ability of the equipment. When the gap is equal, the dry powder mixer has better mixing performance; The smaller the ratio of revolution and rotation angular velocity, the better the mixing performance of the equipment. When the spiral angle of the hollow blade is in the range of 42 ~ 48 °, the dry powder mixer has better mixing performance.

Then, changing the parameters of steering, rotational speed and solid content, the numerical simulation and analysis of the mixing process of dry powder mixer were carried out. The relationship between them and the mixing performance of the equipment was studied. The mixing process parameters were compared with the mixed materials And the simulation results are verified, and the solutions to the problems in the design and manufacturing process are proposed.

The results show that the higher the rotational speed of the stirring blade, the stronger the mixing ability of the equipment, the higher the mixing efficiency, the better the mixing uniformity of the product, but the higher the equipment working ability; the non-periodic adjustment of the stirring blade , Which helps to improve the mixing efficiency of the dry powder mixer and improve the mixing uniformity of the mixed material.
