Reciprocating Kneading and Extruding System (Co-Kneader) Cascade Type

Reciprocating Kneading and Extruding System (Co-Kneader)Cascade Type

1. Application

Reciprocating Kneading and Extruding System (Co-Kneader)Cascade Type for Masterbatch, wire/cable compounds, thermosets, heat-senive material etc, like PE, PP, EVA+CACO3, PS,PA, ABS, PBT, PET, EVA+CARBON, EPDM, NBR, SILASTIC, HDPE, LDPE, LLDPE, MDPE, ETC, HFFR ETC.

2. Main Feature

• Lower energy input, lower melt temperatures.
• Extremely homogenous mixing, no shear spikes, equal treatment of polymer matrix.
• High degree of self-wiping and have no dead spot.
• Dispersive mixing without destroying delicate fillers.
• High volumetric loadings of fillers and additives.
• Efficient blending of liquid components.
• Broad application for compounding without changing hardware.
• Axially opened split barrel guarantees ease of cleaning and fast maintenance.
• Replacement parts, such as screws, barrel lining and pins can be changed individually.

3. Specification

Material silos--gravimetric feeders (4 sets: 1 for PE/EVA, 2 for ATH and 1 for additives) ---vertical feeder (1st& 3rdbarrel sections) + liquid injection system (if required) -- SJW-140 Co-kneader --- cascade extruder --- Eccentric fog cutting system with 2 stage of cooling --- packing

1. 20 L/D. with five-barrel segments.
2. Single screw extruder (cascade type): 200mm 7L/D.
3. Vertical forcing feeder: 2 sets, special design, with higher feeding capacity.
