Extrusion International 6-2017

35 Extrusion International 6/2017 Leistritz: the Masterbatch XXperience The Leistritz booth at FAKUMA The Leistritz Extrusion Technology team has been pre- sented its range of products. This time the focus would be set on the ZSE 35 iMAXX, a twin screw extruder that is especially suited for the use in masterbatch produc- tion. In this field of application, efficient product changes are as important as attaining very good quality and high throughputs. Therefore, the machine was designed to be quite flexible. It has closed, and thus easy-to-clean sur- faces. A stainless steel cover protects the entire process- ing unit and drive unit against accidental contact or con- tamination. The cooling/heating device is fully integraed in the frame. One central water connection is all that is needed for the entire machine. The temperature control, heating and cooling elements are very well positioned. Since they are easy to access they can easily be exchanged or cleaned. A further feature is the adaptable frame length. The stan- dard frame length is designed for process lengths of at least 24 L/D up to maximum of 48 L/D. With a change of formulation, the processing unit can thus be extrended or shortened. Futhermore, a synchronous drive is used in this extruder. This way, Leistritz contributes to an im- proved energy efficiency. Also a torque measurement is installed.
