What type of mixing machine should be used for powdery materials with a high specific gravity that tend to clump together?
Thread Content
The materials need to be mixed together; the main component is ferrous sulfate with 5 molecules of water of crystallization, having a specific gravity of 1.897. The additional ingredients are very fine dry powders, with the proportion of these ingredients being less than 1%. The mixer currently in use is a 10-cubic-meter horizontal screw mixer, and it seems difficult to achieve uniform mixing. (Perhaps a mixer with a smaller volume would be better.) I did some research online, and the commonly used powder mixing equipment available on the market includes twin-screw conical mixers, horizontal gravity-free mixers, horizontal plow-type mixers, and horizontal screw ribbon mixers. Personally, the most suitable mixer might be a twin-screw conical mixer. Please let experienced sea friends discuss this.
Same question: the balling of the spiral ribbon is quite severe. Does the original poster have any information on this?
