About this machine
The Leistritz LSM-30 34 GG is a used twin-screw extruder — sometimes referred to as a co-rotating or counter-rotating extruder depending on configuration — built for processing plastics and similar polymer materials. Twin-screw extruders are widely used in compounding, blending, devolatilisation, and profile extrusion across the plastics processing industry. Leistritz is a well-established German manufacturer with a long history in precision screw technology, producing extruders and related equipment for the plastics, pharmaceutical, and food industries.
This particular machine is a counter-rotating, vented double-screw extruder with a screw diameter of 34 mm, a centre distance of 30 mm, and a screw thread depth of 4 mm. The length-to-diameter ratio stands at 30, and the inlet diameter is 65 mm. The machine bears serial number and was manufactured in 1990. It is currently located in Barneveld, Netherlands.
Drive power is provided by a 3 kW DC motor running on 380 V, with a screw speed of up to 110 rpm. The gearbox operates at 2,200 rpm with a reduction ratio yielding 20 rpm output, and the unit is identified as a Resotec-type gear configuration. The extruder features six electric heating zones and seven cooling zones, giving a total of thirteen thermal control zones along the barrel — a configuration that allows precise temperature management across the processing length.
The machine is equipped with a feed hopper and features exchangeable screw segments, offering flexibility for different processing requirements. All wetted parts are constructed in stainless steel. A vacuum pump is included, supporting the vented barrel design for effective devolatilisation during processing. The unit comes complete with its own switchgear cabinet, which measures 700 × 500 × 450 mm.
The overall machine height is 2 metres, with a floor footprint of 2.75 × 0.91 metres, making it a relatively compact unit suitable for laboratory-scale or small-volume production environments.
