The ‘gentle touch’ mixing principle of Lindor mixers ensures that the quality of the components is preserved. There is hardly any product breakage, dust formation or heating. Thanks to the operating characteristics of plastics are usually good, mixing times can be short, they say from the company. Thanks to these characteristics, large volumes can be obtained, especially if the mixing process is continuous.
From Lindor they point out that capacities “from 5 to 15 (and up to 20) tons / hour” can be reached. An innovative option that simplifies the production process in a batch mixer is the incorporation of a mixing drum as a ‘cyclone’. By creating the vacuum in the tunnel, the granulate can be drawn into the mixer directly from the silo. For this reason, drum mixers are suitable for many applications in the plastics industry.
An important application of Lindor mixers is the homogenization of quality differences in a granulate caused by variations in the extrusion process. Thus, a drum mixer with a capacity of 30 tons can assume the production that an extruder generates in a period of 8 hours. By homogenizing this batch, a granulate of constant quality is achieved.
Some plastics (LDPE, HDPE, PU, PET) undergo a by-product process after extrusion, for example heat treatment, or soaking in an organic liquid (such as a peroxide). These processes are carried out in Lindor double-shell mixers that precisely control conditions, such as temperature. Sometimes these applications are so critical that mixers are applied with special gaskets to reduce product contamination to less than 1 ppm (1 part per million).
