Extrusion International 6-2019

59 Extrusion International 6/2019 The Erlenmeyer flask of the 21st Century The family firm ENTEX Rust &Mitschke from Bochum, Germany is once again represented this year with a stand in the German pavilion at the interplas- tica fair in Moscow (28-31 January 2020). The main attraction at the ex- hibition stand will be the new L-WE 30 laboratory roller extruder. This new development supplements the ENTEX construction kit and can be used for example in the plastics, chemical, food, pharmaceutical or cosmetics industries. Laboratory roller die extruders offer everything that the “big” planetary roller extruders can, just in smaller and more compact sizes. As a result of their versatile fields of application, they are mostly used as test extruders in labora- tories or for producing small quantities. Some industrial production plants with an output capacity of several tonnes per hour have startedon a smaller scale as laboratory roller extruders. For the particular field of application, the materials used in laboratory roller extruders are individually tailored to the customer’s specific process require- ments. The size, processing section length and configuration of a labo- ratory roller extruder have been de- signed on the basis of calculations and decades of experience. What is more, special solutions are nearly always possible. With the new L-WE, the benefits of the planetary roller extruder – abso- lute temperature control and mixing that is appropriate to the active sub- stance, low-shearing thin-layer rolling- efficient andmoreprecise temperature control in different temperature zones. Considerably shorter heating times and thus a much lower loss of energy are another advantage of the modular construction kit, along with the possi- bility of efficient cooling. The new planetary roller extruder by ENTEX combines economy and ecol- ogy, making it the most energy-effi- cient procedure construction kit of the future. The ENTEX team will be happy to pro- vide further more detailed information at the exhibition stand inMoscow. ENTEX Rust & Mitschke GmbH www.entex.de Universal Construction Kit of the Future out, large surface exchange – can now also be used in material-critical areas. ENTEX thus now also covers material quantities of several hundred grams per hour. The liquid-based temperature control systems newly developed by ENTEX, which are also being exhibited, ensure Gravimetric metering unit Temperature control unit L-WE 30 Planetary feed cylinder Roller cylinder The trade fair exhibit, the L-WE 30 laboratory roller extruder: The height of the lavishly designed base frame can be adjusted to the local conditions with the press of a button. In order to achieve high effectiveness and very short reaction times for tempering, it is possible to integrate heat exchangers that can be supplied with primary energy such as pre-heated water into the base frame. Depending on the conveyedmaterial and process parameters, the throughput rate is about 1-10 kg/h.
