Whether the screw mixer has any effect on the powder with different fluidity. Here, the spiral belt mixer is taken as the mixing experiment object.
The working principle of screw belt mixer is mainly under the action of diffusion and agitation, the material is mixed evenly. Its structure features are: screw belt mixer is composed of screw belt, mixer, driving device and frame. The mixer is a half cylinder or a cylinder closed at both ends. The upper part of the mixing barrel is provided with an open cover and feed port to facilitate the entry and exit of materials. The spiral belt mixer has some characteristics that make it may have different mixing results in the face of powder with different fluidity.
The fluidity of powder determines the mixing difficulty of materials, and is also the fundamental reason for all kinds of materials in the existing industry to use efficient mixing equipment to mix evenly.
In this experiment, three kinds of materials were mixed with three sets of screw belt mixer of the same size and power.
1. Experiment 1 is food particles and powdery solids with poor fluidity and mutual adhesion. This kind of powder has certain viscosity and requires sufficient power in mixing. Therefore, it is often necessary to use the mixing equipment with mechanical flipping, pressing, rolling and other actions. After a long time of mixing, the screw belt mixer basically achieves uniformity. However, the food additive industry which requires higher mixing accuracy may not meet the mixing demand.
2, experiment two is the general liquidity, the proportion difference is relatively large metal materials, this kind of material by the simple rotary effect is not enough, because it participates in the mixing of various materials is greater than, and the addition of trace special powder, then it needs the multi-directional and multi-angle role to be able to do full mixing, this situation screw belt mixer simply rely on stirring power has been very laborious, And there are mixed dead ends. Generally use three - dimensional powder mixer or multi - dimensional dual power mixer.
3, Experiment 3 in the material difference is not big, good liquidity granular chemical industry with solid mainly rely on the container itself, or by the container installed in the moving parts of the role, repeatedly turned, mixed and mixed, this situation screw belt mixer mixing basic uniform.
Screw belt mixer for powder mixing, if the uniformity requirement is not high, powder material difference is not big, uniform mixing is not a problem. But no matter what kind of powder state, which industry powder mixing, the selection of efficient dual-power mixing equipment is able to achieve the high efficiency and uniform mixing of the industry needs, but also the needs of The Times of high-end mixing.
