This Buss Ko-Kneter MDK 46 B is a mixer and blender — sometimes referred to as a mixing extruder or kneader-extruder — designed for the continuous compounding and homogenisation of polymers, rubber compounds, and other viscous materials. Buss is a well-established Swiss manufacturer with a long history of producing kneading and compounding machinery for the plastics, rubber, food, and chemical processing industries, and the Ko-Kneter line in particular is widely recognised as a specialist single-screw continuous kneader platform.
This machine was built in 1987, carries machine number 87/652482, and is located in Barneveld, Netherlands. It is configured as a single-screw mixing extruder with a screw diameter of 46 mm and an L/D ratio of 15, giving a processing length of approximately 690 mm. The inlet diameter is 50 mm, and material is fed via an integral hopper. The barrel is constructed from stainless steel and incorporates three heating zones, with a maximum operating temperature of 250 °C.
Drive power is provided by a DC motor rated at 0.710 to 21.5 kW, running on 380 V at 50 Hz, with a motor speed range of 50 to 1,520 rpm. The screw speed is rated at 300 rpm. The entire unit is frame-mounted, with a floor footprint of 2.70 × 0.55 m and a total height of 1.90 m.
The machine is offered with an additional two-roll cylinder unit, featuring rolls of 150 mm diameter and 400 mm length. This auxiliary unit is powered by a 0.55 kW motor suitable for 220/380 V supply at 1,400 rpm, and delivers a roll speed range of 3.6 to 18 rpm — suitable for sheeting or further working of the compounded material discharged from the extruder. The complete package is available in used condition.
