Used Leistritz 60mm ZSE MAXX Twin Screw Extruder – High-Performance Industrial Extruder

Manufacturer’s Info:

• Manufacturer: Leistritz
• Model: ZSE60MAXX-20D
• Serial #: 04144
• Order #: 310.1121.01

Description:
The Leistritz ZSE60MAXX-20D is a high-performance twin screw extruder designed for industrial-scale processing. Featuring two co-rotating screws with an approximate 2.44" diameter and 62" length, this unit operates at 400 rpm and has a 20:1 L/D ratio. Equipped with 4 barrel sections and 1 feed section, it supports both liquid heating and cooling with 4 cooling zones for precise temperature management.

This extruder is powered by a 121 kW (160 HP) motor running at 1600 rpm, driving the screws through a robust gearbox. It includes a Leistritz LSB 56 twin screw side feeder, which is driven by a 3.45 kW, 1700 rpm gear motor with a 5.3:1 ratio. A Rickmeier pump, coupled with a 1.4 kW motor, manages fluid circulation through a Funke plate heat exchanger for efficient temperature control.

The unit includes a drive panel with a Siemens Sinamics controller, though it does not include the main control panel. It is mounted on a frame with wheels and adjustable feet for mobility and easy installation.
