Additive blends must be pure and homogenous because we have multiple products, we have to ensure the highest quality possible with absolutely no contamination between product runs.

One polymer manufacturer in UK request vortex mixing technology to design a suitable ribbon blender which can easily take ribbon shaft out to fully clean inside part of it because they need often changeover product and clean inside part thoroughly to avoid cross-pollution. “Additive blends must be pure and homogenous because we have multiple products, we have to ensure the highest quality possible with absolutely no contamination between product runs.” says the product manager Mr. William. So, it means that they need to do thorough cleaning between each batch and this need take much time on blender cleaning. Furthermore, this company also needs to avoid the risk of worker climbing into the blender for cleaning and maintenance. Mr. William told Vortex Company that safety is the life for their company and they want to avoid any risk of people hurting during blender operation.
After gathered information on what drawbacks the company was experiencing with its other production line’s blender during product changeovers and what capacity the company was hoping to achieve, Vortex start to design a suitable solution for William and also make some customize design.
Firstly, the ribbon blender must be placed under the platform but not be put too low which will make operator difficult to lift the ribbon shaft. The top of cover shall beyond the platform. The removable ribbon is hoisted out using an overhead crane so operators can quickly and easily clean both the ribbon and the inside of blender.
Secondly and the most important is how to design ribbon agitator shaft. To keep and ensure working efficiency of ribbon mixer, Vortex Company design a flat-flange, clamshell coupling which allows operator to lift ribbon agitator shaft out of the blender without moving two end plates and seal assembly.
The final custom-designed ribbon mixer with an agitator ribbon that can be easily and quickly removed without moving any of the drive parts and seal parts, saving much time of changeover and cleaning at every batch. “Since…
