Extruder barrels

Listing ID #3461212

The Pin Barrel Rubber Extruder consists of motor, reduction gear box, feed device, screw, barrel, extrusion head, temperature control unit, electric control device and frame, and so on.
Main motor is a DC motor with DC speed adjuster, gear reducer is multi-step tooth surface hardened type, and immersion lubricationoil pump are adopted.
Feed device is double-walled design for water cooling, and feed roll is designed for water cooling with a rotary joint and adjustable scraper knife for continuous cleaning and is driven by splined coupling ring.
screw is made of nitrided steel 38CrMoAIA, surface hardened by nitriding, nitriding depth 0.5~0.7mm, and surface hardness 900HV, extrusion barrel is drilled for water cooling and heating with 7~12 pin rows, each have 6~12pins and is made of nitrided steel 38CrMoAIA in bore surface hardened by nitriding, nitriding depth 0.5~0.7mm, and surface hardness approx.950HV.
Temperature control unit (TCU) for the cooling of screw, pin barrel, feed barrel, feed roll, and extrusion head.
Frame is welded by steel profiles.
