Higher performance requirements, new raw material properties, a modified process sequences or increasing quality demands there are numerous reasons for adjusting the parameter of a production line. Often the material preparation as first step in the process chain is not considered properly. However in particular an optimized mixture is the key to reproducible top level result. The function of these mixers is to distribute stabilizer, lubricants, fillers and modifiers homogeneously and economically and transform this mixture into a dust-free, dry and free flowing condition.

The heating mixer has the purpose to mix the material and all components between 5 to 8 minutes while heating them to a temperature of 100C to 300C. This process binds all compounds to the material particles. However, at this temperature the combining waxes are still slightly sticky and the compound tends to omit press compact. That is why the mixed compound will be discharged from the heating mixer to the cooling mixer, where it will be cooled down to approx. 400C. After preparation, the mixing material is cooled in the vertical cooling mixer. The mixing material can then be transported. In the next step, the mixing material can be ensiled and then stored.
