Getting in the mix
Batch and continuous mixers play a key role in the plastics sector as they are vital in the creation of blends, compounds and masterbatch for a range of applications
Mixing is the special sauce that helps create unique plastic blends and compounds – which could be used in applications as different as high-pressure pipe, medical tubing or a new formulation of PVC for a window frame. Equipment suppliers are looking to provide more
effective mixing with improved plant utilisation – and, since the emergence of the Covid pandemic, improved remote access and monitoring. MTI Mischtechnik of Germany offers a range of
laboratory mixers, which have heatable and coolable mixing vessels. The all-round machines are suitable for the
scope of bulk material processing tasks including the production of trial mixtures and small-scale production batches in laboratories and technology centres, says the company. Applications include masterbatches and compounds for the plastics and rubber industry – including the production of natural fibre compounds. The laboratory mixer range includes the type M
vertical high-speed mixers (which have a working volume up to 28 litres), heating/cooling mixer combinations from the M/KMV series (working cooling mixer volume up to 51 litres) and the Uni tec type UT vertical universal mixers (working volume up to 51 litres). On a small scale, they cover the range of conventional industrial applications from homog-

enisation via friction mixing, coating, agglomera- tion and granulation to drying. All MTI laboratory mixers share the same Plug-&-Play layout, ensuring immediate usability and convenient handling – together with easy cleaning, to enable rapid formulation changes and good emptying characteristics, to maximise product yields. Various add-ons – such as liquid addition lances, choppers or the newly developed aspiration systems – expand the range of applica- tions and enable reliable process design. The company R&D centre in Detmold gives customers the chance to test laboratory mixers equipped in line with their requirements. Whether the mixer is operated in manual or fully
automatic mode, the electronics acquire any desired measurement data which can be securely stored on local and cloud-based media and allow in-process and subsequent analysis – including on mobile devices. The ability to store numerous mixing programs means processes can be reliably and reproducibly repeated at any time. “Our laboratory mixers are in use worldwide for trialling formulations and manufacturing small batches,” said Ulrich Schär, general manager at MTI. “Our customers appreciate their versatility – without the modifications often required for other systems – and the ability to acquire all process and machine parameters for use in reliable process scale-up.”
