With so many different materials being used these days for building purposes, users are becoming increasingly aware of how important it is to prepare the materials correctly. The wrong choice of mixing paddle for mixing materials can later result in expensive repairs to buildings, or at least longer mixing times and unnecessary physical strain. Collomix offers a wide range of professional mixing paddles where you are certain to find exactly the help you need.
For optimum mixing results it is very important to choose the right mixing paddle. Your decision should be based on two factors: Mixing volume and type of material. Mixing volume will determine the diameter (size) of the mixing paddle, while the kind of material will determine its geometry, i.e. the mixing method or mixing action.
Below are three categories of mixing actions:
1. From the bottom up (positive action)
The material is conveyed upwards through the middle of the mixing paddle from the bottom of the bucket and flows down again at the sides. This method should be used for powdery and dry mixtures such as mortar, plaster, grout, cement, and quartz- and pebble-filled materials. The mixing paddle works into the mixing material easily. ### 2. From the top down (negative action) The material is forced down from the top and then flows back up again at the sides. Any lumps are broken up by the high force generated by the drive and the user, without splashing. This method is ideal for thin-bodied materials such as paints, dispersions, materials containing fibers, and gypsum plaster. It involves greater strain on the drive unit and user. ### 3. Parallel mixing action The material is swirled on a single plane, the components only flow up or down when the mixing tool is moved accordingly. The suction effect results in optimal mixing results, according to the consistency of the material. This method is ideal for fillers. Fewer air inclusions in the material and, as a rule, higher shear forces, prevent the formation of lumps.
