centring rails on the floor are required. Zeppelin has also developed what Kreis describes as a special multiple round bar-profile style tool to achieve best mixing quality based on the vertical mixing position. He says this significantly improves homogeni- sation and dispersion. “The quite common build-ups and caking [that can occur with] difficult materials are minimised or even eliminated,” he says.

(Container Mixer Series) for compounds and master- batches. These are exchangeable, static, non-rotating high-intensity mixing containers with tip speeds of 10 to 60 m/s. R&D manager Henning Kreis says the series has been designed for very easy handling and gives “excellent” dispersing results. “The outstanding container handling is a real novelty on the market,” claims Kreis. “By using the latest design of tilting brackets, the container docking is very easy, even with larger machines,” he says. “The container clamping to the mixing head is carried out by a centring fork and spindle stroke gear at the container head. This leads to very high tensioning forces and additional safety by means of self-retention of the spindle stroke gear and motor brake.” Container movement, driving-in and centring into the
mixer is carried out by this automatic centring fork. “No matter which position the container is entered, it will be centred automatically to the precise position for lifting,” Kreis says. He adds that no additional guidance units or

turbomixer, in single configuration or combined with its CMX horizontal cooler, for the production of products such as PVC dry-blend, wood-plastics composites, masterbatch and various powders. The company, which also offers the TRX high speed container mixer, claims to have delivered 80 mixing plants in the two years since it was founded. Sales this year are likely to be double those of 2014, according to a representative. Promixon recently inaugurated a new 1,500 m2 building, which includes a test room for customers to try out materials and equipment. Major developments at the company have focused on mixing tools with enhanced performance, increased cooling efficiency, energy savings, and an extended range of mixing devices designed to cope with the wide variety of mixing demands by its customers. Promixon cites its recent supply of a Problend-
