For rotating joints and swiffels you have come to the right place!
Conventional solution: stirring arms and screws The dry substances you work with, sometimes don’t have a natural flow. The accurate dosing of these substances is therefore often a challenge. In conventional machines screws and stirring arms are applied to dose the dry substances. The substance is in motion, but there is a risk of damage, segregation, ratholing, bridging and compacting of your dry material. As a result the dosing is not accurate, material is lost and the continuous flow of your production process is at risk.
In addition, the many moving components and contact parts require extra maintenance, so there is a relatively large risk of damage.
The Hethon solution: Flexible Wall Hopper
Hethon dosing machines are equipped with a Flexible Wall Hopper: a wall hopper with a flexible exterior of sustainable Polyurethane. By externally, mechanically and evenly massaging the wall hopper walls, by use of paddles, the dry substances continuously keep in motion. Thus the material is transported smoothly towards the dosing screw. As the mechanical paddles are not inside the wall hopper, as opposed to the stirring arms and screws, the dry material will not get damaged and ratholing or bridging is prevented. Therefore even poorly flowing and compacting raw materials are easily and accurately dosed. It is also possible to have the screw and the paddles move quicker or more slowly, independently. This way one can fiddle with the proper settings.
